For live migrate we need the allow-two-primaries option,
but we don't know exactly if we are called for a migration operation.
Now also check if at least any of the resources is in use somewhere and
only then set the option.
This fixes a limitation for arm64/aarch64 KVM hosts to correctly export
the product name via sysconfig attribute. Without this `cloud-init`
doesn't function correctly on arm64 platforms.

If a Linstor node is down while migrating resource, allow-two-primaries
setting will fail because we can't reach the downed node. But it will
still set the property on the other nodes and migration should work.
We now just report an error instead of completely failing.

* CKS: remove tests of creating/deleting HA clusters as they are covered by the upgrade test
* Update PR 8402 as suggested
* test: remove CKS cluster if fail to create or verify
* veeam: detach only the restored volume during backup restore
Steps to reproduce the issue
1. create a VM (A) with ROOT and DATA disk
2. assign to a backup offering
3. create backup
4. create another VM (B)
5. restore the DATA disk of VM A, and attach to VM B
6. When operation is done, check the datastore
Without this change, the ROOT image is not removed and left over on the datastore.

* vmware: create restored volume with new UUID and attach to VM
This PR fixes several issues in the testing of Veeam 11 and Veeam12
- Import Veeam.Backup.PowerShell and silently ignore the warning messages
- Fix issue when assign vm to backup offerings, which caused by separator (\r\n)
- Fix authorization failure in veeam 12a, which is because v1_4 is not supported in veeam 12a any more
- Fix exception if backup name has space
- Fix backup metrics in veeam12, which is because powershell command does not return the values needed
- Fix Incorrect datetime value, which is because powershell command returns a datetime which is not supported in Java
- Fix issue during backup restoration if VM has both ROOT and DATA disks.
This PR also has the following update
- Add integration test test/integration/smoke/test_backup_recovery_veeam.py
- Make some UI changes
- Add zone setting backup.plugin.veeam.version. If it is not set, CloudStack will get veeam version via powershell commands.
- Add zone setting backup.plugin.veeam.task.poll.interval and backup.plugin.veeam.task.poll.max.retry
1. Problem description
In Apache CloudStack (ACS), when a VM is deployed in a host with the KVM hypervisor, an XML file is created in the assigned host, which has a property shares that defines the weight of the VM to access the host CPU. The value of this property has no unit, and it is a relative measure to calculate how much CPU a given VM will have in the host. However, this value has a limit, which depends on the version of cgroup utilized by the host's kernel. The problem lies at the range value of shares that varies between both versions: [2, 264144] for cgroups version 1; and [1, 10000] for cgroups version 2. Currently, ACS calculates the value of shares using Equation 1, presented below, where CPU is the number of cores and speed is the CPU frequency; both specified in the VM's compute offering. Therefore, if a compute offering has, for example, 6 cores at 2 GHz, the shares value will be 12000 and an exception will be thrown by libvirt if the host utilizes cgroup v2. The second version is becoming the default one in current Linux distributions; thus, it is necessary to address this limitation.
Equation 1
shares = CPU * speed
Fixes: #6744
2. Proposed changes
To address the problem described, we propose to apply a scale conversion considering the max shares of the host. Using the same formula currently utilized by ACS, it is possible to calculate the maximum shares of a VM for a given host. In other words, using the number of cores and the nominal speed of the host's CPU as the upper limit of shares allowed to a VM. Then, this value will be scaled to the allowed interval of [1, 10000] of cgroup v2 by using a linear scale conversion.
The VM shares would be calculated as Equation 2, presented below, where VM requested shares is the requested shares value calculated using Equation 1, cgroup upper limit is fixed with a value of 10000 (cgroups v2 upper limit), and host max shares is the maximum shares value of the host, calculated using Equation 1. Using Equation 2, the only case where a VM passes the cgroup v2 limit is when the user requests more resources than the host has, which is not possible with the current implementation of ACS.
Equation 2
shares = (VM requested shares * cgroup upper limit)/host max shares
To implement the proposal, the following APIs will be updated: deployVirtualMachine, migrateVirtualMachine and scaleVirtualMachine. When a VM is being deployed, a new verification will be added to find a suitable host. The max shares of each host will be calculated, and the VM calculated shares will be verified if it does not surpass the host's value. Likewise, the migration of VMs will have a similar new verification. Lastly, the scale of VMs will also have the same verification for the VM's host.
To determine the max shares of a given host, we will use the same equation currently used in ACS for calculating the shares of VMs, presented in Section 1. When Equation 1 is used to determine the maximum shares of a host, CPU is the number of cores of the host, and speed is the nominal CPU speed, i.e., considering the CPU's base frequency.
It is important to note that these changes are only for hosts with the KVM hypervisor using cgroup v2 for now.
This PR fixes the test failures with CKS HA-cluster upgrade.
In production, the CKS HA cluster should have at least 3 control VMs as well.
The etcd cluster requires 3 members to achieve reliable HA. The etcd daemon in control VMs uses RAFT protocol to determine the roles of nodes. During upgrade of CKS with HA, the etcd become unreliable if there are only 2 control VMs.
Making a diskful resource was meant as an optimization,
but cannot work on non hyperconverged setups,
as the storage nodes (diskful) are not part of the cloudstack cluster.
A TODO was overseen and never implemented,
which could trigger the following bug:
If Linstor didn't create a resource (diskless or diskfull) on
the cloudstack choosen node, it would not be able to copy the
template data there, it even seems no error was
triggered and the new template file silently just became
empty/corrupt.
This fixes the following cases in which Solidfire storage integration
caused issues when using Solidfire datadisks with VMware:
1. Take Volume Snapshot of Solidfire data disk
2. Delete an active Instance with Solidfire data disk attached
3. Attach used existing Solidfire data disk to a running/stopped VM
4. Stop and Start an instance with Solidfire data disks attached
5. Expand disk by resizing Solidfire data disk by providing size
6. Expand disk by changing disk offering for the Solidfire data disk
Additional changes:
- Use VMFS6 as managed datastore type if the host supports
- Refactor detection and splitting of managed storage ds name in storage
processor
- Restrict storage rescanning for managed datastore when resizing
