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.
Fixes: #4883
* server: fix failed to apply userdata when enable static nat
* server: fix cannot expunge vm as applyUserdata fails
* configdrive: fix ISO is not recognized when plug a new nic
* configdrive: detach and attach configdrive ISO as it is changed when plug a new nic or migrate vm
* configdrive test: (1) password file does not exists in recreated ISO; (2) vm hostname should be changed after migration
* configdrive: use centos55 template with sshkey and configdrive support
* configdrive: disklabel is 'config-2' for configdrive ISO
* configdrive: use copy for configdrive ISO and move for other template/volume/iso
* configdrive: use public-keys.txt
* configdrive test: fix (1) update_template ; (2) ssh into vm by keypair
This PR intends to improve logging on agent start to facilitate troubleshooting.

* 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.
(1) does not work:
```
/usr/share/cloudstack-common/scripts/vm/network/vnet/modifyvxlan.sh -v 1001 -p eth1 -b brvx-1001 -o add
```
"bridge fdb" shows
```
00:00:00:00:00:00 dev vxlan1001 dst 239.0.3.233 via eth1 self permanent
```
(2) this works:
```
/usr/share/cloudstack-common/scripts/vm/network/vnet/modifyvxlan.sh -v 1001 -p cloudbr1 -b brvx-1001 -o add
```
"bridge fdb" shows

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
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

```
To make testing easier, step 1 and 2 can be replaced by
```
qemu-img create -f qcow2 -b <backing file> <qcow2 image>
```
so qcow2 image does not have a backing file format.

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.
