Currently, our compute offerings and disk offerings are tightly coupled with respect to many aspects. For example, if a compute offering is created, a corresponding disk offering entry is also created with the same ID as the reference. Also creating compute offering takes few disk-related parameters which anyway goes to the corresponding disk offering only. I think this design was initially made to address compute offering for the root volume created from a template. Also changing the offering of a volume is tightly coupled with storage tags and has to be done in different APIs either migrateVolume or resizeVolume. Changing of disk offering should be seamless and should consider new storage tags, new size and place the volume in appropriate state as defined in disk offering.

* Fix of creating volumes from snapshots without backup
When few snaphots are created onyl on primary storage, and try to create
a volume or a template from the snapshot only the first operation is
successful. Its because the snapshot is backup on secondary storage with
wrong SQL query. The problem appears on Ceph/NFS but may affects other
storage plugins.
Bypassing secondary storage is implemented only for Ceph primary storage
and it didn't cover the functionality to create volume from snapshot
which is kept only on Ceph

On newer libvirt/qemu it seems PCI hot-plugging could be an issue as
seen in:
https://www.suse.com/support/kb/doc/?id=000019383https://bugs.launchpad.net/nova/+bug/1836065
This was found to be true on ARM64/aarch64 platform (tested on
RaspberryPi4). As per the default machine doc, it advises to
pre-allocate PCI controllers on the machine and pcie-to-pci-bridge based
controller for legacy PCI models:
https://libvirt.org/pci-hotplug.html#x86_64-q35
This patch introduces the concept as a workaround until a proper fix is
done (ideally in the upstream libvirt/qemu projects). Until then client
code can add 32 PCI controllers and a pcie-to-pci-bridge controller for
aarch64 platforms.

Currently there is no disk IO driver configuration for VMs running on KVM. That's OK for most the cases; however, recently there have been added some quite interesting optimizations with the IO driver io_uring.
Note that IO URING requires:
Qemu >= 5.0, and
Libvirt >= 6.3.0.
By using io_uring we can see a massive I/O performance improvement within Virtual Machines running from Local and/or NFS storage.
This implementation enhances the KVM disk configuration by adding workflow for setting the disk IO drivers. Additionally, if the Qemu and Libvirt versions matches with the required for having io_uring we are going to set it on the VM. If there is no support for such driver we keep it as it is nowadays, without any IO driver configured.

* vxlan: arp does not work between hosts as multicast group is communicated over physical nic instead of linux bridge
when linux bridge is setup (refer to http://docs.cloudstack.apache.org/projects/archived-cloudstack-getting-started/en/latest/networking/vxlan.html#configure-product-to-use-vxlan-plugin) and used as the kvm traffic label of physical networks, the vms on different hosts cannot reach each other.

Datastore cluster as a primary storage support is already there. But if any changes at vCenter to datastore cluster like addition/removal of datastore is not synchronised with CloudStack directly. It needs removal of primary storage from CloudStack and add it again to CloudStack.
Here synchronisation of datastore cluster is fixed without need to remove or add the datastore cluster.
1. A new API is introduced syncStoragePool which takes datastore cluster storage pool UUID as the parameter. This API checks if there any changes in the datastore cluster and updates management server accordingly.
2. During synchronisation if a new child datastore is found in datastore cluster, then management server will create a new child storage pool in database under the datastore cluster. If the new child storage pool is already added as an individual storage pool then the existing storage pool entry will be converted to child storage pool (instead of creating a new storage pool entry)
3. During synchronisaton if the existing child datastore in CloudStack is found to be removed on vCenter then management server removes that child datastore from datastore cluster and makes it an individual storage pool.
The above behaviour is on par with the vCenter behaviour when adding and removing child datastore.

* Updated libvirt's native reboot operation for VM on KVM using ACPI event, and Added 'forced' reboot option to stop and start the VM (using rebootVirtualMachine API)
* Added 'forced' reboot option for System VM and Router
- New parameter 'forced' in rebootSystemVm API, to stop and then start System VM
- New parameter 'forced' in rebootRouter API, to force stop and then start Router
* Added force reboot tests for User VM, System VM and Router
These changes are related to PR #3194, but include suspending/resuming the VM when doing a VM snapshot as well, when deleting a VM snapshot, as it is performing the same operations via Libvirt. Also, there was an issue with the UI/localization changes in the prior PR, as that PR was altering the Volume snapshot behavior, but was altering the VM snapshot wording. Both have been altered in this PR.
Issuing this in response to the work happening in PR #4029.
Added support for PowerFlex/ScaleIO (v3.5 onwards) storage pool as a primary storage in CloudStack (for KVM hypervisor) and enabled VM/Volume operations on that pool (using pool tag).
Please find more details in the FS here:
https://cwiki.apache.org/confluence/x/cDl4CQ
Documentation PR: apache/cloudstack-documentation#169
This enables support for PowerFlex/ScaleIO (v3.5 onwards) storage pool as a primary storage in CloudStack
Other improvements addressed in addition to PowerFlex/ScaleIO support:
- Added support for config drives in host cache for KVM
=> Changed configuration "vm.configdrive.primarypool.enabled" scope from Global to Zone level
=> Introduced new zone level configuration "vm.configdrive.force.host.cache.use" (default: false) to force host cache for config drives
=> Introduced new zone level configuration "vm.configdrive.use.host.cache.on.unsupported.pool" (default: true) to use host cache for config drives when storage pool doesn't support config drive
=> Added new parameter "host.cache.location" (default: /var/cache/cloud) in KVM agent.properties for specifying the host cache path and create config drives on the "/config" directory on the host cache path
=> Maintain the config drive location and use it when required on any config drive operation (migrate, delete)
- Detect virtual size from the template URL while registering direct download qcow2 (of KVM hypervisor) templates
- Updated full deployment destination for preparing the network(s) on VM start
- Propagate the direct download certificates uploaded to the newly added KVM hosts
- Discover the template size for direct download templates using any available host from the zones specified on template registration
=> When zones are not specified while registering template, template size discovery is performed using any available host, which is picked up randomly from one of the available zones
- Release the VM resources when VM is sync-ed to Stopped state on PowerReportMissing (after graceful period)
- Retry VM deployment/start when the host cannot grant access to volume/template
- Mark never-used or downloaded templates as Destroyed on deletion, without sending any DeleteCommand
=> Do not trigger any DeleteCommand for never-used or downloaded templates as these doesn't exist and cannot be deleted from the datastore
- Check the router filesystem is writable or not, before performing health checks
=> Introduce a new test "filesystem.writable.test" to check the filesystem is writable or not
=> The router health checks keeps the config info at "/var/cache/cloud" and updates the monitor results at "/root" for health checks, both are different partitions. So, test at both the locations.
=> Added new script: "filesystem_writable_check.py" at /opt/cloud/bin/ to check the filesystem is writable or not
- Fixed NPE issue, template is null for DATA disks. Copy template to target storage for ROOT disk (with template id), skip DATA disk(s)
* Addressed some issues for few operations on PowerFlex storage pool.
- Updated migration volume operation to sync the status and wait for migration to complete.
- Updated VM Snapshot naming, for uniqueness in ScaleIO volume name when more than one volume exists in the VM.
- Added sync lock while spooling managed storage template before volume creation from the template (non-direct download).
- Updated resize volume error message string.
- Blocked the below operations on PowerFlex storage pool:
-> Extract Volume
-> Create Snapshot for VMSnapshot
* Added the PowerFlex/ScaleIO client connection pool to manage the ScaleIO gateway clients, which uses a single gateway client per Powerflex/ScaleIO storage pool and renews it when the session token expires.
- The token is valid for 8 hours from the time it was created, unless there has been no activity for 10 minutes.

Other fixes included:
- Fail the VM deployment when the host specified in the deployVirtualMachine cmd is not in the right state (i.e. either Resource State is not Enabled or Status is not Up)
- Use the physical file size of the template to check the free space availability on the host, while downloading the direct download templates.
- Perform basic tests (for connectivity and file system) on router before updating the health check config data
=> Validate the basic tests (connectivity and file system check) on router
=> Cleanup the health check results when router is destroyed
* Updated PowerFlex/ScaleIO storage plugin version to 4.16.0.0
* UI Changes to support storage plugin for PowerFlex/ScaleIO storage pool.
- PowerFlex pool URL generated from the UI inputs(Gateway, Username, Password, Storage Pool) when adding "PowerFlex" Primary Storage
- Updated protocol to "custom" for PowerFlex provider
- Allow VM Snapshot for stopped VM on KVM hypervisor and PowerFlex/ScaleIO storage pool
and Minor improvements in PowerFlex/ScaleIO storage plugin code
* Added support for PowerFlex/ScaleIO volume migration across different PowerFlex storage instances.
- findStoragePoolsForMigration API returns PowerFlex pool(s) of different instance as suitable pool(s), for volume(s) on PowerFlex storage pool.
- Volume(s) with snapshots are not allowed to migrate to different PowerFlex instance.
- Volume(s) of running VM are not allowed to migrate to other PowerFlex storage pools.
- Volume migration from PowerFlex pool to Non-PowerFlex pool, and vice versa are not supported.
* Fixed change service offering smoke tests in test_service_offerings.py, test_vm_snapshots.py
* Added the PowerFlex/ScaleIO volume/snapshot name to the paths of respective CloudStack resources (Templates, Volumes, Snapshots and VM Snapshots)
* Added new response parameter “supportsStorageSnapshot” (true/false) to volume response, and Updated UI to hide the async backup option while taking snapshot for volume(s) with storage snapshot support.
* Fix to remove the duplicate zone wide pools listed while finding storage pools for migration
* Updated PowerFlex/ScaleIO volume migration checks and rollback migration on failure
* Fixed the PowerFlex/ScaleIO volume name inconsistency issue in the volume path after migration, due to rename failure

The bus type to `data disk` volumes is hardcoded to `virtio` or `scsi`, when using virtio-scsi (or, based on the template type). Therefore, there is no way to specify the bus type to data disk volumes (as we have for root disks).
This PR intends to replicate the `rootDiskController` behavior to `dataDiskController`, allowing the definition of the controller.

This PR fixes a regression issue in #4497
In cloudstack 4.14 or before, the cpu topology is set only when cpucore per socket is set (to 4 or 6).
in other conditions, there is no cpu topology in vm xml definition.
with #4497, vm will have cpu topology in its xml definition, if cpucore per socket is not set.
<topology sockets='<vm cpu cores>' cores='1' threads='1'/>
Not sure if it causes any issue. I think it would be better not to add this part in vm xml definition if cpucore per socket is not set.
Added property to agent.properties that enables or disables the iscsi session clean up feature. #4210
Added a condition to prevent disk partitions from being cleaned up. #4216
This is an extention of #3732 for kvm.
This is restricted to ovs > 2.9.2
Since Xen uses ovs 2.6, pvlan is unsupported.
This also fixes issues of vms on the same pvlan unable to communicate if they're on the same host

This PR adds outputting human readable byte sizes in the management server logs, agent logs, and usage records. A non-dynamic global variable is added (display.human.readable.sizes) to control switching this feature on and off. This setting is sent to the agent on connection and is only read from the database when the management server is started up. The setting is kept in memory by the use of a static field on the NumbersUtil class and is available throughout the codebase.
Instead of seeing things like:

Ceph used to use port 6789 (no need to specify it), but with the messenger v2
from Ceph it switched to port 3300 while 6789 still works.
librados/librbd/libvirt will automatically figure out the ports to use if none is
specified.
Therefor there is no need for CloudStack to explicitely define the port in the XML
passed to Libvirt or Qemu.
Leave blank if no port number has been defined by the user.
When you migrate volume between data stores CS keeps the original UUID and changes the path of the volume.
When volume is not found by the given path the agent throws CloudRuntimeException but it's not catched in LibvirtGetVolumeStatsCommandWrapper.java

When I add a secondary IP to a nic on shared network in advanced zone with security groups, the network rules for new IP are not applied on KVM hypervisors.
It is because "--action -A" cannot be recognized in security_group.py after commit ac73e7e671. changing to "--action=-A" will fix it.
Fixes issue #3590 by using the last element on the array from the snapshot "path" String for retrieving the snapshot id. Additionally, it uses the volumePath as the volume id which should always be the correct value. The error raised on issue #3590 was related to the wrong use of variable "path" where in some cases had a different set of substrings.
The proposed change has been tested and evaluated. The values used for openning the RBD connection and executing the rollback were stable on the tests. Runned rollback on multiple snapshots and could start the VM with the content matching the ROOT reverted snapshot.
KVM is supported on arm64 Linux (https://www.linux-kvm.org/page/Processor_support#ARM:).
For a small (IoT) platform such as the new Raspberry Pi 4 that uses armv8 processor
(cortex-a72) it's possible to run Linux host with `/dev/kvm`
accleration. This adds support for IoT IaaS in CloudStack.
This PR is from a fun weekend project where:
- I set up a Raspberry Pi 4 - 4GB RAM model with 4 CPU cores @ 1.5Ghz, 128GB SD samsung evo plus card
- Installed Ubuntu 19.10 raspi3 base image: http://cdimage.ubuntu.com/releases/19.10/release/ubuntu-19.10-preinstalled-server-arm64+raspi3.img.xz
- Build a custom Linux 5.3 kernel with KVM enabled, deb here: http://dl.rohityadav.cloud/cloudstack-rpi/kernel-19.10/ and install the linux-image and linux-module
- Then install/setup CloudStack on it (fix some issues around jna, by manually installing newer libjna-java to /usr/share/cloudstack-agent/lib)
- Since the host processor is not x86_64, I had to build a new arm64 (or aarch64) systemvmtemplate: http://dl.rohityadav.cloud/cloudstack-rpi/systemvmtemplate/
I could finally get a 4.13 CloudStack + Adv zone/networking to run on it
and deployed a KVM based Ubuntu 19.10 environment and NFS storage.
Deployed a test vm with isolated network, VR works as expected. Console
proxy works as well, for this tested against arm64 openstack Debian 9/10
templates.
I raised the issue of enabling KVM in upstream Ubuntu arm64 build: https://bugs.launchpad.net/ubuntu/+source/linux-raspi2/+bug/1783961
Ubuntu kernel team has come back and future arm64 releases may have
KVM enabled by default.
Limitation: on my aarch64 env, it did not support IDE, therefore all
default bus type for volumes are SCSI by default. With VIRTIO it fails
sometimes.

There are certain scenarios where the 169.254.0.0/16 subnet is used for different
purposes then CloudStack on a hypervisor.
Once of such scenarios is a BGP+EVPN+VXLAN setup using BGP Unnumbered where the
169.254.0.1 address is used by Frr/Zebra BGP routing to send traffic to the
neighboring router.
The following settings can be changed in the agent.properties (default values added):
control.cidr=169.254.0.0/16
Make sure the global setting 'control.cidr' matches the values defined in the agent.propeties!
In the future the mgmt server can send this parameter to a KVM Agent on startup, but at the moment
this framework is not in place and thus these values can't be send to the Agent in a proper manner.

Currently when refreshing disk usage stats all kvm agents are asked to collect stats for all volumes. In setups with multiple kvm hosts where managed storage is used, not all volumes are attached to all kvm hosts, this results in a large number of warnings in the kvm agent logs. This change introduces a filter step in case managed storage is used so that the management server only requests kvm agents for stats about volumes that are connected to each kvm host.

This change addresses #3089. There was an issue when disks were being added with bus type IDE when creating windows VMs from ISOs. It is not possible to select bus type when creating a VM with an ISO. The bus type is inferred based on the platform emulator string provided to the KVM agent. Currently when creating a VM with managed storage (ex: Solidfire) and OS type string Windows*, all disks are added as IDE. Qemu currently does not support multiple IDE controllers and this configuration results in VMs that cannot be started. This issue does not occur when using NFS as the storage provider due to logic in that KVM agent that makes all data volumes (non root) use a virtio controller for file based disk. Similar logic was added for raw physical disks so that managed storage has the same behavior as NFS. In addition specific versions were removed from the code that guesses the disk controller to be used based on the platform emulator string since most modern operating systems support virtio.
Fixes#3089
Feature Specification: https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=95653548
Live storage migration on KVM under these conditions:
From source and destination hosts within the same cluster
From NFS primary storage to NFS cluster-wide primary storage
Source NFS and destination NFS storage mounted on hosts
In order to enable this functionality, database should be updated in order to enable live storage capacibilty for KVM, if previous conditions are met. This is due to existing conflicts between qemu and libvirt versions. This has been tested on CentOS 6 hosts.
Additional notes:
To use this feature set the storage_motion_supported=1 in the hypervisor_capability table for KVM. This is done by default as the feature may not work in some environments, read below.
This feature of online storage+VM migration for KVM will only work with CentOS6 and possible Ubuntu as KVM hosts but not with CentOS7 due to:
https://bugs.centos.org/view.php?id=14026https://bugzilla.redhat.com/show_bug.cgi?id=1219541
On CentOS7 the error we see is: " error: unable to execute QEMU command 'migrate': this feature or command is not currently supported" (reference https://ask.openstack.org/en/question/94186/live-migration-unable-to-execute-qemu-command-migrate/). Reading through various lists looks like the migrate feature with qemu may be available with paid versions of RHEL-EV but not centos7 however this works with CentOS6.
Fix for CentOS 7:

The KVM Agent had two mechanisms for reporting its capabilities
and memory to the Management Server.
On startup it would ask libvirt the amount of Memory the Host has
and subtract and add the reserved and overcommit memory.
When the HostStats were however reported to the Management Server
these two configured values on the Agent were no longer reported
in the statistics thus showing all the available memory in the
Agent/Host to the Management Server.
This commit unifies this by using the same logic on Agent Startup
and during statistics reporting.
memory=3069636608, reservedMemory=1073741824
This was reported by a 4GB Hypervisor with this setting:
host.reserved.mem.mb=1024
The GUI (thus API) would then show:
Memory Total 2.86 GB
This way the Agent properly 'lies' to the Management Server about its
capabilities in terms of Memory.
This is very helpful if you want to overprovision or undercommit machines
for various reasons.
Overcommitting can be done when KSM or ZSwap or a fast SWAP device is
installed in the machine.
Underprovisioning is done when the Host might run other tasks then a KVM
hypervisor, for example when it runs in a hyperconverged setup with Ceph.
In addition internally many values have been changed from a Double to a Long
and also store the amount of bytes instead of Kilobytes.

We can not safely assume that the first device listed under a bridge is the

We need to filter out those devices and then fetch the physical device attached

These additional RBD features allow for faster lookups of how much space a RBD
image is using, but with the exclusive locking we prevent two VMs from writing
to the same RBD image at the same time.
These are the default features used by Ceph for any new RBD image.

On actual testing, I could see that kvmheartbeat.sh script fails on NFS
server failure and stops the agent only. Any HA VMs could be launched
in different hosts, and recovery of NFS server could lead to a state
where a HA enabled VM runs on two hosts and can potentially cause
disk corruptions. In most cases, VM disk corruption will be worse than
VM downtime. I've kept the sleep interval between check/rounds but
reduced it to 10s. The change in behaviour was introduced in #2722.

Prevents errors while migrating VM from ISO:
Test 1: Deploy VM from ISO -> Live migrate VM to another host -> ERROR
Test 2: Register ISO using Direct Download on KVM -> Deploy VM from ISO -> Live migrate VM to another host -> ERROR
- Prevent NullPointerException migrating VM from ISO
- Prevent mount secondary storage on ISO direct downloads on KVM
Since we support only Ubuntu 16.04+ on master/4.12+, we can now use
the libvirt service name `libvirtd` for all distributions. This also
fixes an optional package name for libvirtd installation on Debian 9+.
Fixes#2909

Windows has support for several paravirt features that it will use when running on Hyper-V, Microsoft's hypervisor. These features are called enlightenments. Many of the features are similar to paravirt functionality that exists with Linux on KVM (virtio, kvmclock, PV EOI, etc.)
Nowadays QEMU/KVM can also enable support for several Hyper-V enlightenments. When enabled, Windows VMs running on KVM will use many of the same paravirt optimizations they would use when running on Hyper-V.
A number of years ago, a PR was introduced that added a good portion of the code to enable this feature set, but it was never completed. This PR enables the existing features. The previous patch set detailed in #1013 also included the tests.
By selecting Windows PV, the enlightenment additions will be applied to the libvirt configuration. This is support on Windows Server 2008 and beyond, so all currently supported versions of Windows Server.
In our testing, we've seen benchmark improvements of around 20-25% running on Centos 7 hosts and it is also supported on Centos/RHEL 6.5 and later. Testing on Ubuntu would be appreciated.
