* CLOUDSTACK-10160: Fix typo in Libvirt XML definition for Virtio-SCSI
The attribute for the XML element 'controller' should be 'model' and
not 'mode'.
Source: https://libvirt.org/formatdomain.html#elementsControllers
A scsi controller has an optional attribute model, which is one of
'auto', 'buslogic', 'ibmvscsi', 'lsilogic', 'lsisas1068', 'lsisas1078',
'virtio-scsi' or 'vmpvscsi'.
In the current state a regular SCSI device is attached and not a Virtio-SCSI
device.

Allow security policies to apply on port groups:
- Accepts security policies while creating network offering
- Deployed network will have security policies from the network offering
applied on the port group (in vmware environment)
- Global settings as fallback when security policies are not defined for a network

- Default promiscuous mode security policy set to REJECT as it's the default

Portgroup vlan-trunking options for dvswitch: This allows admins to define
a network with comma separated vlan id and vlan
range such as vlan://200-400,21,30-50 and use the provided vlan range to
configure vlan-trunking for a portgroup in dvswitch based environment.
VLAN overlap checks are performed for:
- isolated network against existing shared and isolated networks
- dedicated vlan ranges for the physical/public network for the zone
- shared network against existing isolated network
Allow shared networks to bypass vlan overlap checks: This allows admins
to create shared networks with a `bypassvlanoverlapcheck` API flag
which when set to 'true' will create a shared network without
performing vlan overlap checks against isolated network and against
the vlans allocated to the datacenter's physical network (vlan ranges).
Notes:
- No vlan-range overlap checks are performed when creating shared networks
- Multiple vlan id/ranges should include the vlan:// scheme prefix

Host-HA offers investigation, fencing and recovery mechanisms for host that for
any reason are malfunctioning. It uses Activity and Health checks to determine
current host state based on which it may degrade a host or try to recover it. On
failing to recover it, it may try to fence the host.
The core feature is implemented in a hypervisor agnostic way, with two separate
implementations of the driver/provider for Simulator and KVM hypervisors. The
framework also allows for implementation of other hypervisor specific provider
implementation in future.
The Host-HA provider implementation for KVM hypervisor uses the out-of-band
management sub-system to issue IPMI calls to reset (recover) or poweroff (fence)
a host.
The Host-HA provider implementation for Simulator provides a means of testing
and validating the core framework implementation.

This introduces a new certificate authority framework that allows
pluggable CA provider implementations to handle certificate operations
around issuance, revocation and propagation. The framework injects
itself to `NioServer` to handle agent connections securely. The
framework adds assumptions in `NioClient` that a keystore if available
with known name `cloud.jks` will be used for SSL negotiations and
handshake.
This includes a default 'root' CA provider plugin which creates its own
self-signed root certificate authority on first run and uses it for
issuance and provisioning of certificate to CloudStack agents such as
the KVM, CPVM and SSVM agents and also for the management server for
peer clustering.
Additional changes and notes:
- Comma separate list of management server IPs can be set to the 'host'
global setting. Newly provisioned agents (KVM/CPVM/SSVM etc) will get
radomized comma separated list to which they will attempt connection
or reconnection in provided order. This removes need of a TCP LB on
port 8250 (default) of the management server(s).
- All fresh deployment will enforce two-way SSL authentication where
connecting agents will be required to present certificates issued
by the 'root' CA plugin.
- Existing environment on upgrade will continue to use one-way SSL
authentication and connecting agents will not be required to present
certificates.
- A script `keystore-setup` is responsible for initial keystore setup
and CSR generation on the agent/hosts.
- A script `keystore-cert-import` is responsible for import provided
certificate payload to the java keystore file.
- Agent security (keystore, certificates etc) are setup initially using
SSH, and later provisioning is handled via an existing agent connection
using command-answers. The supported clients and agents are limited to
CPVM, SSVM, and KVM agents, and clustered management server (peering).
- Certificate revocation does not revoke an existing agent-mgmt server
connection, however rejects a revoked certificate used during SSL
handshake.
- Older `cloudstackmanagement.keystore` is deprecated and will no longer
be used by mgmt server(s) for SSL negotiations and handshake. New
keystores will be named `cloud.jks`, any additional SSL certificates
should not be imported in it for use with tomcat etc. The `cloud.jks`
keystore is stricly used for agent-server communications.
- Management server keystore are validated and renewed on start up only,
the validity of them are same as the CA certificates.
New APIs:
- listCaProviders: lists all available CA provider plugins
- listCaCertificate: lists the CA certificate(s)
- issueCertificate: issues X509 client certificate with/without a CSR
- provisionCertificate: provisions certificate to a host
- revokeCertificate: revokes a client certificate using its serial
Global settings for the CA framework:
- ca.framework.provider.plugin: The configured CA provider plugin
- ca.framework.cert.keysize: The key size for certificate generation
- ca.framework.cert.signature.algorithm: The certificate signature algorithm
- ca.framework.cert.validity.period: Certificate validity in days
- ca.framework.cert.automatic.renewal: Certificate auto-renewal setting
- ca.framework.background.task.delay: CA background task delay/interval

The 'force' option provided with the stopVirtualMachine API command is
often assumed to be a hard shutdown sent to the hypervisor, when in fact
it is for CloudStacks' internal use. CloudStack should be able to send
the 'hard' power-off request to the hosts.
When forced parameter on the stopVM API is true, power off (hard shutdown)
a VM. This uses initial changes from #1635 to pass the forced parameter
to hypervisor plugin via the StopCommand, and fixes force stop (poweroff)
handling for KVM, VMware and XenServer.

CLOUDSTACK-9698 [VMware] Make hardcoded wait timeout for NIC adapter hotplug as configurable
Description
=========
Currently ACS waits for 15 seconds (hard coded) for hot-plugged NIC in VR running on VMware to get detected by guest OS.
The time taken to detect hot plugged NIC in guest OS depends on type of VMware NIC adapter like (E1000, VMXNET3, E1000e etc.)
and guest OS itself. In uncommon scenarios the NIC detection may take longer time than 15 seconds,
in such cases NIC hotplug would be treated as failure which results in VPC tier configuration failure.
Alternatively making the wait timeout for NIC adapter hotplug as configurable will be helpful for admins in such scenarios. This is specific to VR running over VMware hypervisor.
Also in future if VMware introduces new NIC adapter types which may take time to get detected by guest OS, it is good to have flexibility of
configuring the wait timeout as fallback mechanism in such scenarios.
Fix
===
Introduce new configuration parameter (via ConfigKey) "vmware.nic.hotplug.wait.timeout" which is "Wait timeout (milli seconds) for hot plugged NIC of VM to be detected by guest OS." as fallback instead of hard coded timeout, to ensure flexibility for admins given the listed scenarios above.

CLOUDSTACK-8663: Fixed various issues to allow VM snapshots and volume snapshots to exist together
Fix HVM VM restart bug in XenServer
CLOUDSTACK-9363: Fix HVM VM restart bug in XenServerHere is the longer description of the problem:
By default XenServer limits HVM guests to only 4 disks. Two of those are reserved for the ROOT disk (deviceId=0) and CD ROM (device ID=3) which means that we can only attach 2 data disks. This limit however is removed when Xentools is installed on the guest. The information that a guest has Xentools installed and can handle more than 4 disks is stored in the VM metadata on XenServer. When a VM is shut down, Cloudstack removes the VM and all the metadata associated with the VM from XenServer. Now, when you start the VM again, even if it has Xentools installed, it will default to only 4 attachable disks.
Now this problem manifests itself when you have a HVM VM and you stop and start it with more than 2 data disks attached. The VM fails to start and the only way to start the VM is to detach the extra disks and then reattach them after the VM start.
In this fix, I am removing the check which is done before creating a `VBD` which enforces this limit. This will not affect current workflow and will fix the HVM issue.
@koushik-das this is related to the "autodetect" feature that you introduced a while back (https://issues.apache.org/jira/browse/CLOUDSTACK-8826). I would love your review on this fix.

CLOUDSTACK-9619: Updates for SAN-assisted snapshotsThis PR is to address a few issues in #1600 (which was recently merged to master for 4.10).
In StorageSystemDataMotionStrategy.performCopyOfVdi we call getSnapshotDetails. In one such scenario, the source snapshot in question is coming from secondary storage (when we are creating a new volume on managed storage from a snapshot of ours thats on secondary storage).
This usually worked in the regression tests due to a bit of "luck": We retrieve the ID of the snapshot (which is on secondary storage) and then try to pull out its StorageVO object (which is for primary storage). If you happen to have a primary storage that matches the ID (which is the ID of a secondary storage), then getSnapshotDetails populates its Map<String, String> with inapplicable data (that is later ignored) and you dont easily see a problem. However, if you dont have a primary storage that matches that ID (which I didnt today because I had removed that primary storage), then a NullPointerException is thrown.
I have fixed that issue by skipping getSnapshotDetails if the source is coming from secondary storage.
While fixing that, I noticed a couple more problems:
1) We can invoke grantAccess on a snapshot thats actually on secondary storage (this doesnt amount to much because the VolumeServiceImpl ignores the call when its not for a primary-storage driver).
2) We can invoke revokeAccess on a snapshot thats actually on secondary storage (this doesnt amount to much because the VolumeServiceImpl ignores the call when its not for a primary-storage driver).
I have corrected those issues, as well.
I then came across one more problem:
When using a SAN snapshot and copying it to secondary storage or creating a new managed-storage volume from a snapshot of ours on secondary storage, we attach to the SR in the XenServer code, but detach from it in the StorageSystemDataMotionStrategy code (by sending a message to the XenServer code to perform an SR detach). Since we know to detach from the SR after the copy is done, we should detach from the SR in the XenServer code (without that code having to be explicitly called from outside of the XenServer logic).
I went ahead and changed that, as well.

CLOUDSTACK-9619: Updates for SAN-assisted snapshots
Signed-off-by: Rajani Karuturi <rajani.karuturi@accelerite.com>
This commit implements basic Security Grouping for KVM in
Basic Networking.
It does not implement full Security Grouping yet, but it does:
- Prevent IP-Address source spoofing
- Allow DHCPv6 clients, but disallow DHCPv6 servers
- Disallow Instances to send out Router Advertisements
The Security Grouping allows ICMPv6 packets as described by RFC4890
as they are essential for IPv6 connectivity.
Following RFC4890 it allows:
- Router Solicitations
- Router Advertisements (incoming only)
- Neighbor Advertisements
- Neighbor Solicitations
- Packet Too Big
- Time Exceeded
- Destination Unreachable
- Parameter Problem
- Echo Request
ICMPv6 is a essential part of IPv6, without it connectivity will break or be very
unreliable.
For now it allows any UDP and TCP packet to be send in to the Instance which
effectively opens up the firewall completely.
Future commits will implement Security Grouping further which allows controlling UDP and TCP
ports for IPv6 like can be done with IPv4.
Regardless of the egress filtering (which can't be done yet) it will always allow outbound DNS
to port 53 over UDP or TCP.

(2) add new API to create volume snapshot from vm snapshot
(3) delete metadata of vm snapshots before stopping/migrating and recover vm snapshots after starting/migrating
(4) enable deleting of VM snapshot on stopped vm or vm snapshot is not listed in qcow2 image.
(5) enable smoke tests for vmsnaphsots on KVM
While remote executing commands/scripts through SSH in VR, ACS uses system vm keyfile.
ACS is fetching this key file using VMwareContext object which encapsulates vCenter connection handle.
This is inefficient because of dependency on getServiceContext() which means a vCenter connection
handle which is not required just to fetch a file in name space in management server.

This commit adds a additional VirtIO channel with the name
'org.qemu.guest_agent.0' to all Instances.
With the Qemu Guest Agent the Hypervisor gains more control over the Instance if
these tools are present inside the Instance, for example:
* Power control
* Flushing filesystems
* Fetching Network information
In the future this should allow safer snapshots on KVM since we can instruct the
Instance to flush the filesystems prior to snapshotting the disk.
More information: http://wiki.qemu.org/Features/QAPI/GuestAgent
Keep in mind that on Ubuntu AppArmor still needs to be disabled since the default
AppArmor profile doesn't allow libvirt to write into /var/lib/libvirt/qemu
This commit does not add any communication methods through API-calls, it merely
adds the channel to the Instances and installs the Guest Agent in the SSVMs.
With the addition of the Qemu Guest Agent channel a second channel appears in /dev
on a SSVM as a VirtIO port.
The order in which the ports are defined in the XML matters for the naming inside
the SSVM VM and by not relying on /dev/vportXX but looking for a static name the
SSVM still boots properly if the order in the XML definition is changed.
A SSVM with both ports attached will have something like this:
root@v-215-VM:~# ls -l /dev/virtio-ports
total 0
lrwxrwxrwx 1 root root 11 May 13 21:41 org.qemu.guest_agent.0 -> ../vport0p2
lrwxrwxrwx 1 root root 11 May 13 21:41 v-215-VM.vport -> ../vport0p1
root@v-215-VM:~# ls -l /dev/vport*
crw------- 1 root root 251, 1 May 13 21:41 /dev/vport0p1
crw------- 1 root root 251, 2 May 13 21:41 /dev/vport0p2
root@v-215-VM:~#
In this case the SSVM port points to /dev/vport0p1, but if the order in the XML
is different it might point to /dev/vport0p2
By looking for a portname with a pre-defined pattern in /dev/virtio-ports we
do not rely on the order in the XML definition.

CLOUDSTACK-9379: Support nested virtualization at VM level on VMware Hypervisor## Introduction
[JIRA TICKET](https://issues.apache.org/jira/browse/CLOUDSTACK-9379)
It is desired to support nested virtualization at VM level for VMware hypervisor. Current behaviour supports enabling/desabling global nested virtualization by modifying global config `'vmware.nested.virtualization'`. It is wished to improve this feature, having control at VM level instead of a global control only.
A new global configuration is added, to enable/disable VM nested virtualization control: `'vmware.nested.virtualization.perVM'`. Default value=false
After a vm deployment or start command, vm params include `'nestedVirtualizationFlag'` key and its value is:
- true -> nested virtualization enabled
- false -> nested virtualization disabled
**We will determinate nested virtualization enabled/disabled by examining this 3 values:**
- **(1)** global configuration `'vmware.nested.virtualization'` value
- **(2)** global configuration `'vmware.nested.virtualization.perVM'` value
- **(3)** `'nestedVirtualizationFlag'` value in `user_vm_details` if present, `null` if not.
Using this 3 values, there are different use cases:
- **(1)** = TRUE, **(2)** = TRUE, **(3)** is null -> _ENABLED_
- **(1)** = TRUE, **(2)** = TRUE, **(3)** = TRUE -> _ENABLED_
- **(1)** = TRUE, **(2)** = TRUE, **(3)** = FALSE -> _DISABLED_
- **(1)** = TRUE, **(2)** = FALSE, **(3)** indifferent -> _ENABLED_
- **(1)** = FALSE, **(2)** = TRUE, **(3)** is null -> _DISABLED_
- **(1)** = FALSE, **(2)** = TRUE, **(3)** = TRUE -> _ENABLED_

This PR adds an ability to Pass a new parameter, locationType,
to the “createSnapshot” API command. Depending on the locationType,
we decide where the snapshot should go in case of managed storage.
There are two possible values for the locationType param
1) `Standard`: The standard operation for managed storage is to
keep the snapshot on the device. For non-managed storage, this will
be to upload it to secondary storage. This option will be the
default.
2) `Archive`: Applicable only to managed storage. This will
keep the snapshot on the secondary storage. For non-managed
storage, this will result in an error.
The reason for implementing this feature is to avoid a single
point of failure for primary storage. Right now in case of managed
storage, if the primary storage goes down, there is no easy way
to recover data as all snapshots are also stored on the primary.
This features allows us to mitigate that risk.
In VmwareResource, findRouterEthDeviceIndex() method find ethernet interface index given
the mac address. This method is used, once a nic is plugged to determine ethernet interface.
"/proc/sys/net/ipv4/conf" from the VR and looped through the devices to find the right
ethernet interface. However current logic read it once, and loops through the device list.
Its observerd device may not show up '/proc/sys/net/ipv4/conf' immediatly once NIC is plugged
in the VM from vCenter.Fix ensured, while waiting for 15 sec in the loop, read the latest
content from /proc/sys/net/ipv4/conf, so that right device list is processed.
By adding a Random Number Generator device to Instances we can prevent
entropy starvation inside guest.
The default source is /dev/random on the host, but this can be configured
to another source when present, for example a hardware RNG.
When enabled it will add the following to the Instance's XML definition:
<rng model='virtio'>
<rate period='1000' bytes='2048' />
<backend model='random'>/dev/random</backend>
</rng>
If the Instance has the proper support, which most modern distributions have,
it will have a /dev/hwrng device which it can use for gathering entropy.

CLOUDSTACK-9422: Granular 'vmware.create.full.clone' as Primary Storage setting### Introduction
For VMware, It is possible to decide creating VMs as full clones on ESX HV, adjusting `vmware.create.full.clone` global setting. We would like to introduce this property as a primary storage detail, and use its value instead of global setting's value.
We propose introducing `fullCloneFlag` on `PrimaryDataStoreTO` sent on `CopyCommand`. This way we can reconfigure `VmwareStorageProcessor` and `VmwareStorageSubsystemCommandHandler` similar as it was done for `nfsVersion` but refactoring it to be more general.

Adding support for cross-cluster storage migration for managed storage when using XenServerThis PR adds support for cross-cluster storage migration of VMs that make use of managed storage with XenServer.
Managed storage is when you have a 1:1 mapping between a virtual disk and a volume on a SAN (in the case of XenServer, an SR is placed on this SAN volume and a single virtual disk placed in the SR).
Managed storage allows features such as storage QoS and SAN-side snapshots to work (sort of analogous to VMware VVols).
This PR focuses on enabling VMs that are using managed storage to be migrated across XenServer clusters.
I have successfully run the following tests on this branch:
TestVolumes.py
TestSnapshots.py

CLOUDSTACK-9428: Fix for CLOUDSTACK-9211 - Improve performance of 3D GPU support in cloud-plugin-hypervisor-vmwareJIRA TICKET: https://issues.apache.org/jira/browse/CLOUDSTACK-9428
### Introduction
On #1310 passing vRAM size to support 3D GPU problem was addressed on VMware. It was found out that it could be improved to increase performance by reducing extra API calls, as we'll describe later
### Improvement
On WMware, `VmwareResource` manages execution of `StartCommand.` Before sending power on command to ESXi hypervisor, vm is configured by calling `reconfigVMTask` web method on vSphere's client `VimPortType` web service.
It was found out that we were using this method 2 times when passing vRAM size, as it implied creating a new vm config spec only editing video card specs and making an extra call to `reconfigVMTask.`
We propose reducing the extra web service call by adjusting vm's config spec. This way video card gets properly configured (when passing vRAM size) in the same configure call, increasing performance.
### Use case (passing vRAM size)
* Deploy a new VM, let its id be X
* Stop VM
* Execute SQL, where X is vm's id and Z is vRAM size (in kB):
````
INSERT INTO cloud.user_vm_details (vm_id, name, value) VALUES (X, 'mks.enable3d', 'true');
INSERT INTO cloud.user_vm_details (vm_id, name, value) VALUES (X, 'mks.use3dRenderer', 'automatic');
INSERT INTO cloud.user_vm_details (vm_id, name, value) VALUES (X, 'svga.autodetect', 'false');

Often, patch and security releases do not require schema migrations or
data migrations. However, if an empty upgrade class and associated
scripts are not defined, the upgrade process will break. With this
change, if a release does not have an upgrade, a noop DbUpgrade is added
to the upgrade path. This approach allows the upgrade to proceed and
for the database to properly reflect the installed version. This change
should make the release process simpler as RMs no longer need to
rememeber to create this boilerplate code when starting a new release.
Beginning with the 4.8.2.0 and 4.9.1.0 releases, the project will
formally adopt a four (4) position release number to properly accomodate
rekeases that contain only CVE fixes. The DatabaseUpgradeChecker and
Version classes made assumptions that they would always parse and
compare three (3) position version numbers. This change adds the
CloudStackVersion value object that supports both three (3) and four (4)
version numbers. It encapsulates version comparsion logic, as well as,
the rules to allow three (3) and four (4) to interoperate.
* Modifies DatabaseUpgradeChecker to handle derive an upgrade path for
a version that was not explicitly specified. It determines the
releases the first release before it with database migrations and uses
that list as the basis for the list for version being calculated. A
noop upgrade is then added to the list which causes no schema changes
or data migrations, but will update the database to the version.
* Adds unit tests for the upgrade path calculation logic in
DatabaseUpgradeChecker
* Removes dummy upgrade logic for the 4.8.2.0 introduced in previous
versions of this patch
* Introduces the CloudStackVersion value object which parses and
compares three (3) and four (4) position version numbers. This class
is intended to replace com.cloud.maint.Version.
* Adds the junit-dataprovider dependency -- allowing test data to be
concisely generated separately from the execution of a test case.
Used extensively in the CloudStackVersionTest.

CLOUDSTACK-9368: Fix for Support configurable NFS version for Secondary Storage mounts## Description
JIRA TICKET: https://issues.apache.org/jira/browse/CLOUDSTACK-9368
This pull request address a problem introduced in #1361 in which NFS version couldn't be changed after hosts resources were configured on startup (for hosts using `VmwareResource`), and as host parameters didn't include `nfs.version` key, it was set `null`.
## Proposed solution
In this proposed solution `nfsVersion` would be passed in `NfsTO` through `CopyCommand` to `VmwareResource`, who will check if NFS version is still configured or not. If not, it will use the one sent in the command and will set it to its storage processor and storage handler. After those setups, it will proceed executing command.

Taking fast and efficient volume snapshots with XenServer (and your storage provider)A XenServer storage repository (SR) and virtual disk image (VDI) each have UUIDs that are immutable.
This poses a problem for SAN snapshots, if you intend on mounting the underlying snapshot SR alongside the source SR (duplicate UUIDs).
VMware has a solution for this called re-signaturing (so, in other words, the snapshot UUIDs can be changed).
This PR only deals with the CloudStack side of things, but it works in concert with a new XenServer storage manager created by CloudOps (this storage manager enables re-signaturing of XenServer SR and VDI UUIDs).
I have written Marvin integration tests to go along with this, but cannot yet check those into the CloudStack repo as they rely on SolidFire hardware.
If anyone would like to see these integration tests, please let me know.

This feature allows root administrators to define new roles and associate API
permissions to them.
A limited form of role-based access control for the CloudStack management server
API is provided through a properties file, commands.properties, embedded in the
WAR distribution. Therefore, customizing API permissions requires unpacking the
distribution and modifying this file consistently on all servers. The old system
also does not permit the specification of additional roles.

https://cwiki.apache.org/confluence/display/CLOUDSTACK/Dynamic+Role+Based+API+Access+Checker+for+CloudStack
DB-Backed Dynamic Role Based API Access Checker for CloudStack brings following
changes, features and use-cases:
- Moves the API access definitions from commands.properties to the mgmt server DB
- Allows defining custom roles (such as a read-only ROOT admin) beyond the
current set of four (4) roles
- All roles will resolve to one of the four known roles types (Admin, Resource
Admin, Domain Admin and User) which maintains this association by requiring
all new defined roles to specify a role type.
- Allows changes to roles and API permissions per role at runtime including additions or
removal of roles and/or modifications of permissions, without the need
of restarting management server(s)
Upgrade/installation notes:
- The feature will be enabled by default for new installations, existing
deployments will continue to use the older static role based api access checker
with an option to enable this feature
- During fresh installation or upgrade, the upgrade paths will add four default
roles based on the four default role types
- For ease of migration, at the time of upgrade commands.properties will be used
to add existing set of permissions to the default roles. cloud.account
will have a new role_id column which will be populated based on default roles
as well
Dynamic-roles migration tool: scripts/util/migrate-dynamicroles.py
- Allows admins to migrate to the dynamic role based checker at a future date
- Performs a harder one-way migrate and update
- Migrates rules from existing commands.properties file into db and deprecates it
- Enables an internal hidden switch to enable dynamic role based checker feature

Removed unnecessary code from getGuestOsType in CitrixResourceBaseConsidering that all mapping of Guest OS Names to their respective hypervisor compatible types is made thorugh accessing a database, we've decided to remove a bit of code in the XcpOssResource class which was doing that same thing for 2 different OS's (both of which ARE in the database). That has led us to a bunch of unused parameters in the getGuestOsType method from its superclass, which we've also decided to remove. Test cases were added for four different possibilities for the platformEmulator String: one for a null String, one for a blank String, one for an empy String and one for a random case with a valid String.

CLOUDSTACK-9231: Root volume migration from one primary to another primary storage within the same cluster is failing
This situation arises when there are two management server accessing the same database.
When the migration request comes the command is forwarded from one management server to another because
the host is owned by the second management server. So, serialization of map from one to another fails.
This is fixed by converting the maps to lists.

Quota service while allowing for scalability will make sure that the cloud is
not exploited by attacks, careless use and program errors. To address this
problem, we propose to employ a quota-enforcement service that allows resource
usage within certain bounds as defined by policies and available quotas for
various entities. Quota service extends the functionality of usage server to
provide a measurement for the resources used by the accounts and domains using a
common unit referred to as cloud currency in this document. It can be configured
to ensure that your usage won’t exceed the budget allocated to accounts/domain
in cloud currency. It will let user know how much of the cloud resources he is
using. It will help the cloud admins, if they want, to ensure that a user does
not go beyond his allocated quota. Per usage cycle if a account is found to be
exceeding its quota then it is locked. Locking an account means that it will not
be able to initiat e a new resource allocation request, whether it is more
storage or an additional ip. Needless to say quota service as well as any action
on the account is configurable.
Changes from Github code review:
- Added marvin test for quota plugin API
- removed unused commented code
- debug messages in debug enabled check
- checks for nulls, fixed access to member variables and feature
- changes based on PR comments
- unit tests for UsageTypes
- unit tests for all Cmd classes
- unit tests for all service and manager impls
- try-catch-finally or try-with-resource in dao impls for failsafe db switching
- remove dead code
- add missing quota calculation case (regression fixed)
- replace tabs with spaces in pom.xmls
- quota: though default value for quota_calculated is 0, the usage server
makes it null while entering usage entries. Flipping the condition so
as to acocunt for that.
- quotatypes: fix NPE in quota type
- quota framework test fixes
- made statement period configurable
- changed default email templates to reflect the fact that exhausted quota may not result in a locked account
- added quotaUpdateCmd that refreshes quota balances and sends alerts and statements
- report quotaSummary command returns quota balance, quota usage and state for all account
- made UI framework changes to allow for text area input in edit views
- process usage entries that have greater than 0 usage
- orocess quota entries only if tariff is non zero
- if there are credit entries but no balance entry create a dummy balance entry
- remove any credit entries that are before the last balance entry
when displaying balance statement
- on a rerun the last balance is now getting added

So far only 1 controller (scsi or ide) is supported in Cloudstack for ide or

then subsequent attach operation should find free unit number on the controller and attach
the virtual disk there.

commit #5
Editing global configuration param vmware.root.disk.controller osdefault value results
in loss of previous root disk controller type. Hence root disk's controller type for legacy
VMs is unknow post that modificaiton by user. If VM is stop/start then we could get this
infromation from bus info of existing volume. But if user resets VM and then try to start VM.
The existing bus info would be lost. Hence existing disk info is not available to depend on.
Using lsilogic or generic scsi controller for ROOT disk of legacy VMs if reset.
commit #4
Avoid adding additional (>1) scsi controllers to system vms. While attaching volume to legacy VM
don't use osdefault optoin which applicable only for VM created with the option enabled, use
legacy data disk controller type (lsilogic)
commit #3
If root disk's controller type is scsi and data disk controller type condenses
to any of scsi sub-types then data disk controller type would fall back to root disk controller itself. This
ensures data volumes would be accessible in all cases as controller of root volume would be reliable
and it means VM has the supported controller. It also avoids mix of scsi controller sub-types in a user instance.

Adds disk serial ids based on volume uuids to the virt xml. This may be useful
for appliances/software that needs some serial ids on the VM disks. This does not
impact existing/running VMs, the vm virt xmls will be updates for running VMs
the next time they are stopped/started.
For testing, disk serial (of debian based systemvm) in the virt xml matched that
in /sys/devices/pci0000:00:0000:00:07.0/virtio4/block/vda/serial.
We currently don't support scsi-blcok devices for which serial is not supported,
for this we've added a DeviceType (LUN) which may be used in future and a check
to not add the serial to the xml if disk type is LUN.

CLOUDSTACK-9062: Improve S3 implementation.The S3 implementation is far from finished, this commit focuses on the bases.
- Upgrade AWS SDK to latest version.
- Rewrite S3 Template downloader.
- Rewrite S3Utils utility class.
- Improve addImageStoreS3 API command.
- Split various classes for convenience.
- Various minor improvements and code optimizations.
A side effect of the new AWS SDK is that it, by default, uses the V4 signature. Therefore I added an option to specify the Signer, so it stays compatible with previous versions.
Please review thoroughly, both code inspection and (automated) integration tests. Currently no integration tests are available specifically for S3. Therefore the implementation is needed to be tested manually, for now...
What I tested:
- Greenfield install -> will download latest systemvm template automatically to S3.
- Upload a template/iso
- Download a template/iso
- Restart of management server -> list available templates -> doesn't download them again if available.

The S3 implementation is far from finished, this commit focusses on the bases.
- Upgrade AWS SDK to latest version.
- Rewrite S3 Template downloader.
- Rewrite S3Utils utility class.
- Improve addImageStoreS3 API command.
- Split various classes for convenience.
- Various minor improvements and code optimalisations.
A side effect of the new AWS SDK is that it, by default, uses the V4 signature. Therefore I added an option to specify the Signer, so it stays compatible with previous versions.

sysctl: don't modify /etc/sysctl.confTo configure firewall rules, CloudStack modifies `/etc/sysctl.conf` and
execute those modifications. This may be harmful for several reasons:
1. `/etc/sysctl.conf` may be managed by some configuration management
system. Such a system will constantly restore the previous version.
2. `/etc/sysctl.conf` may contain additional properties that have been
changed later by some system administrator (for example, once a
firewall has been configured, forwarding may have been activated
while it is disabled in `/etc/sysctl.conf`). Executing the file
again at a later time may disrupt the system.
3. Entries are added again and again. `/etc/sysctl.conf` will contain

Guys, can you review it? things need to be discussed:
(1) this supports KVM/QCOW2 only. Anyone want to implement for other Hypervisor/format ?
(2) The original data volume (on primary storage) will be removed.
(3) The script uses the default timeout in libvirtComputingResource. Do we need to add one in global configuration (like copy.volume.wait or backup.snapshot.wait, create.volume.from.snapshot.wait)
(4) In scripts/storage/qcow2/managesnapshot.sh, I use "qemu-img convert -f qcow2 -O qcow2" to copy the snapshot from secondary to primary (hence there is no base image file), instead of "cp -f", this is because convert is faster than cp in my testing.

In order to test PR #725 using simulator some of these changes are needed.
Based on the way HV check is present in the scale VM API, had to explicitly put simulator related check to allow support. The ideal way would be to remove all these HV specific check from code and made them some configuration (by putting them in hypervisor_capabilities table in DB).

Default to notify only script to handle non-CLVM/QCOW cases.This relates to [CLOUDSTACK-8732](https://issues.apache.org/jira/browse/CLOUDSTACK-8732)
Before this commit the call to `getResizeScriptType` would throw an exception (earlier versions returned `null`, which was fine) - this caused the RBD case to fail. By changing the default to notify only we fix the case for any non-CLVM and non-QCOW cases, too.
This is RBD for now, but this should extend to new storage types supported by Libvirt natively in future.
This is my first attempted contribution: I can see a case for adding RBD logic to the actual getResizeScriptType call, too, but I felt that putting it `LibvirtResizeVolumeCommandWrapper.java` kept the special-casing of RBD (and comments about that) in one place.
### Caveat:
With Libvirt 1.2.2 this actually doesn't do the right thing - but it does do what the documentation *says* should be the right thing, so I'm going to test if this is a Libvirt bug which is fixed in a later version.
(To make it work I need to execute something like:
virsh blockresize --path vda --size 100G i-7-44-VM
where vda is the path as far as the *guest* is concerned, and not an `rbd/` path - which *should* work, but doesn't.)

CLOUDSTACK-8443: Support CentOS 7 as KVM hypervisorThis adds support for CentOS 7 as a KVM hypervisor. As discussed in the Jira issue, the root cause of the issue was the `cloudstack-setup-agent` script that added this line to `/etc/libvirt/qemu.conf`:
`cgroup_controllers=["cpu"]`
On CentOS 6 this 'works', but since by default no cgroups are mounted, this setting is ignored by `libvirtd`. On CentOS 7 is does not work, because the `cpu` and `cpuacct` are 'co-mounted'. This simpy means you cannot use one without the order. The config line above instructs `libvirtd` to only use the `cpu` cgroup, which it can't.
There was code added to make sure the `cpu` cgroup was not co-mounted. It did this with a shell script, but after a reboot it was gone. It wasn't reliable and not even a solution at all. I went ahead and removed the code, because the co-mounted cgroups work fine. The real issue was the config line we put in `/etc/libvirt/qemu.conf` so much better to fix that instead.
The default for `libvirtd` is to use only cgroups that are mounted. When you remove the 'cgroup_controllers' line, the default kicks in. According to the `qemu.conf` file, the default is:
`cgroup_controllers = ["cpu", "devices", "memory", "blkio", "cpuacct", "net_cls"]`
Then again, if it's not mounted, it's not used. So, that's a nice way to control it.
This works just fine for both RHEL/CentOS 6 and RHEL/CentOS 7.
Along the debugging, I came across some small issues here and there which I also fixed in this PR.
If you test this, be sure to build RPMs from this branch and install those on the KVM hypervisor.
At Schuberg Philis we run KVM hypervisors on CentOS 7 for months with these fixes. Now I took the time to fix the issues in CloudStack, rather than work around them.
@bhaisaab @karuturi could you please review this? Thanks!
Please note:
The next step is to fix CLOUDSTACK-8625 (Systemd profile for KVM Agent) as currently a sysvinit script is still used. Although it works, we do not have any systemd benefits. As it is a separate issue, I'll try to address it in a separate PR.

CLOUDSTACK-8443: display the right hypervisor type
CLOUDSTACK-8443: don't try to fix co-mounted cgroups
Signed-off-by: Remi Bergsma <github@remi.nl>
This setting works on CentOS 6 / RHEL 6 but does nothing, as
"cpu" cgroup is not mounted. On CentOS 7 / RHEL 7 systemd does
mount cgroups and "cpu" is co-mounted with "cpuacc". Hence, if
we specify "cpu" then this results in an error because it can
only use them both, or none.
By removing the setting, we rely on the default of qemu, which
is:
cgroup_controllers = ["cpu", "devices", "memory", "blkio", "cpuacct", "net_cls"]
Only if they are really mounted, they will be used. So, this will
work on both version 6 and 7.
The 'fix script' didn't work well, as after a reboot you'd still have qemu
throwing errors. Now we can handle the co-mountedcgroups.

KVM hosts which are actuall up, but if their agents are shutdown should be put
in disconnected state. This would avoid getting the VMs HA'd and other commands
such as deploying a VM will exclude that host and save us from errors.
The improvement is that, we first try to contact the KVM host itself. If it fails
we assume that it's disconnected, and then ask its KVM neighbours if they can
check its status. If all of the KVM neighbours tell us that it's Down and we're
unable to reach the KVM host, then the host is possibly down. In case any of the
KVM neighbours tell us that it's Up but we're unable to reach the KVM host then
we can be sure that the agent is offline but the host is running.

- With the changes added by the rVPC work, the bump priority became deprecated.
This commit includes a refactor to get it removed from the following resources:
* Java classes
* domain_router table - removing the is_priority_bumpup column
* Fixing unit tests
All changes were tested with:
XenServer 6.2 running under our VMWare zone
CloudStack Management Server running on MacBook Pro
MySql running on MackBook Pro
Storage Type: Local
Started the refactor of the XenServer56Resource class
- Unit test added
Changing the CitrixRequestWrapper in order to cope with multiple resources classes and commands
Still have to remove few methods form CitrixResourceBase
- Unit tests added
In the executeRequest I needed to keep the following:
// We need this one because the StorageSubSystemCommand is from another hierarchy.
if (cmd instanceof StorageSubSystemCommand) {
return storageHandler.handleStorageCommands((StorageSubSystemCommand) cmd);
}
- Added basic tests
- Changed the way RebootCommand gets called from RebootRouterCommand
- Made a couple of methods public in the CitrixResourceBase and its subclasses
Sonarcube is great, but has no context and can be wrong, in this
case File.separator is nice if you're running platform independent,
the agent on OVM3 is however NOT platform independent and will break
if we feed it windows separators.
The copy command reply can have null size returned, so check and set values

Fix: RTNETLINK errors
- Management Server health check trying to create already existing interface
- Changes on update_config.py, cs_guestnetwork.py, merger.py
Fix: replace RRouTER_LOG in the CsRedundant.py per log file location
Fix: Guest Net address association during Router restart
- Changes on NicProfileHelper, NicProfileHelperImpl
Fix: aggregationExecution() method on VirtualNetworkApplianceManagerImpl
- Do not send an AggregationControlCommand to a non-configured router
Some classes have been formatted.
Added a source column to the user table.
Source now has only two values UNKNOWN,LDAP with UNKNOWN being the
default and is an enum is com.cloud.User.
When the source is UNKNOWN, the old method of authenticating against all
the available authenticators is used. If a source is available, only
that particular authenticator will be used.
added overloaded methods in AccountService to createUserAccount and
createUser with source specified.

MigrateVMWithVolumes-
1. If ESXi host version is below 5.1, ensure destination datastore(s) is mounted on the source host, then migrate the storage and then finally migrate the VM.
If destination storage(s) is not mounted on the source host,
- In case of NFS storage mount the storage(s).
- In case of VMFS storage fail the request for migration.
2. If EXi host version is 5.1 or above, simultaneously migrate the VM and its storage to the destination host and storage(s) respectively for both NFS and VMFS storage.
This is a plugin that puts in ovm3 support ranging from 3.3.1 to 3.3.2. Basic
functionality is in here, advanced networking etc..
Snapshots only work when a VM is stopped now due to the semantics of OVM's raw
image implementation (so snapshots should work on a storage level underneath the
hypervisor shrug)

When there is large size VR configuration (aggregate commands) copying data to VR using vmops plugin was failed
because of the ARG_MAX size limitation. The configuration data size is around 300KB.
Updated this to create file in host by scp with file contents. This will create file in host.
Then copy the file from the host to VR using hte vmops createFileInDomr method.
In host file get created in /tmp/ with name VR-<UUID>.cfg, once it copied to VR this file will be removed.
Refactored to use the XPatch expressions to check the generated domain xml rathern than string comparison.

Fixed some issues with the polling logic to handle scenarios when SSVM is destroyed/down.
Also changed the status of the volume_store_ref entries so that subsequent operations work fine.
KVMStoragePoolManager is a singleton in practice, any plugin
or extension of LibvirtComputingResource will need to act on
the specific instance of KVMStoragePoolManager that LibvirtComputingResource
has initialized. Therefore, expose this variable for those who
wish to call storage commands from plugins or extensions.

1. If a VM by the same name exists on a different cluster in the VMware DC, unregister the existing VM and continue with the VM start.
2. If VM start succeeds, delete VM files associated with the unregistered VM.
3. If VM start fails, re-register the unregistered VM.

On default iptables rules are updated to add ACCEPT egress traffic.
If the network egress default policy is false, CS remove ACCEPT and adds the DROP rule which
is egress default rule when there are no other egress rules.
If the CS network egress default policy is true, CS won't configure any default rule for egress because
router already came up to accept egress traffic. If there are already egress rules for network then the
egress rules get applied on VR.
For isolated network with out firewall service, VR default allows egress traffic (guestnetwork --> public network)
Findbugs will report error on this as it is expecting true/false for Boolean value.
But we have diffrent meaning for null so it is false positive case from findbug

Look for a VM in vCenter based on both the vCenter name and CS internal name (required in case 'vm.instancename.flag' is enabled).
During Attach Volume and Volume Migration, for lookup and other operations use VM's name as obtained from vCenter instead of using the name set in the agent command.
GPU enabled hosts from non-GPU VM deployment.
Cluster reordering is based on the number of unique host tags in a cluster,
cluster with most number of unique host tags will put at the end of list.
Hosts with GPU capability will get tagged with implicit tags defined by
global config param 'implicit.host.tags' at the time os host discovery.
Also added FirstFitPlannerTest unit test file.

Clearly show if a volume is found and if not, that the pool is being refreshed
and the fetch is tried again.
Due to my commit b53a9dcc9f the chance of a volume
not being found is slightly bigger, but the performance gain is enormous on larger
deployments.
This is why we clearly have to log that we are refreshing the pool information
when a volume is not found.
It could be that a volume is created on host A and a few seconds later host B tries
to access the volume. In that case host B's libvirt doesn't know about the volume
yet and has to refresh the pool before it does.

Support offline volume resize on ESX by creating a worker VM to attach the unattached volume to and then resize it.
(cherry picked from commit 65ed25b7a6)
While expunging a volume, CS chooses the endpoint to perform delete operation by selecting any host that has the storage containing the volume mounted on it.
Instead, if the volume to be deleted is attached to a VM, the endpoint chosen by CCP should be the host that contains the VM.

If CCP thread local context which is used to handle connections to a vCenter is being re-used, validate that the context corresponds to the right vCenter API session.

On larger (especially RBD) storage pools this can take a lot of
time slowing operations like creating volumes down.
The getStorageStats command will still ask a pool to be refreshed so
that the management server has accurate information about the storage pools.
On larger deployments, with thousands of volumes in one pool, this should
significantly improve storage related operations

cleaning up vmsync changes, checkvirtualmachine command was updated to return the

Fix the bug by removing the command CreateEntityDownloadURLCommand from the host delegation. This results in same ssvm for creating the symlink on ssvm and same public ip being used for generating the url on MS.
1. While destroying a ROOT volume do the lookup of the associated VM under the DC and not just cluster.
2. In case of VMware, during VM start if a volume is being recreated no need to detach the old volume because
we now expunge it immediately and don't wait for the storage cleanup task to run.
During VM start while configuring its disk devices, obtain the matching disk for a volume in storage
using both the volume's path and volume's datastore information.
While adding host to existing cluster which is using Nexus 1000v as a network backend, skip validation of Nexus VSM as it was already done while adding that cluster.

than english. To overcome this now we started using ProcessId >= 0 filter
