* 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
In previous cloudstack versions, qcow2 image does not have a backing file format.
however, it is required in newer qemu versions, for example qemu 4.2 on ubuntu 20.04.
steps to reproduce the issue
(1) install cloudstack 4.14 or previous version, and ubuntu 19.04 or 18.04/16.04 LTS.
(2) create vms.
(3) upgrade to 4.15, upgrade os to ubuntu 20.04 , or install a new server with ubuntu 20.04.
(4) migrate vm from old ubuntu version to ubuntu 20.04, failed with exception below

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 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:
Create repo file on /etc/yum.repos.d/:
[qemu-kvm-rhev]
name=oVirt rebuilds of qemu-kvm-rhev
baseurl=http://resources.ovirt.org/pub/ovirt-3.5/rpm/el7Server/
mirrorlist=http://resources.ovirt.org/pub/yum-repo/mirrorlist-ovirt-3.5-el7Server
enabled=1
skip_if_unavailable=1
gpgcheck=0
yum install qemu-kvm-common-ev-2.3.0-29.1.el7.x86_64 qemu-kvm-ev-2.3.0-29.1.el7.x86_64 qemu-img-ev-2.3.0-29.1.el7.x86_64
Reboot host

To make sure that a qemu2-image won't be corrupted by the snapshot deletion procedure which is being performed after copying the snapshot to a secondary store, I'd propose to put a VM in to suspended state.

When I use SandyBridge as custom cpu in my testing, vm failed to start due to following error:
```
org.libvirt.LibvirtException: unsupported configuration: guest and host CPU are not compatible: Host CPU does not provide required features: avx, xsave, aes, tsc-deadline, x2apic, pclmuldq
```
With this patch, it works with the following setting in agent.properties:
```
guest.cpu.mode=custom
guest.cpu.model=SandyBridge
guest.cpu.features=-avx -xsave -aes -tsc-deadline -x2apic -pclmuldq
```
vm cpu is defined as below:
```
<cpu mode='custom' match='exact'>
<model fallback='allow'>SandyBridge</model>
<feature policy='disable' name='avx'/>
<feature policy='disable' name='xsave'/>
<feature policy='disable' name='aes'/>
<feature policy='disable' name='tsc-deadline'/>
<feature policy='disable' name='x2apic'/>
<feature policy='disable' name='pclmuldq'/>
</cpu>
```
