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 bug introduced in #8502. Timeout for script execution was set to 60 ms instead of 60s which resulted in host not getting UEFI enabled. This is a blocker for 4.19 release.
We do this by introducing a new agent parameter `agent.script.timeout` (default - 60 seconds) to use as a timeout for the script checking host's UEFI status.
We also externalize the timeout for the ReadyCommand by introducing a new global setting `ready.command.wait` (default - 60 seconds).
For ModifyStoragePoolCommand, we don't externalize the timeout to avoid confusion for the user. Since, the required timeout can vary depending on the provider in use and we are only setting the wait for default host listener for now. Instead, we reuse the global `wait` setting by dividing it by `5` making the default value of 6 minutes (1800/5 = 360s) for ModifyStoragePoolCommand.
Note: the actual time, the MS waits is twice the wait set for a Command. Check reference code below.

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
There are a lot of test failures due to test_vm_life_cycle.py in multiple PRs due to host not available for migration of VMs.
#8438 (comment)

#7344 (comment)
While debugging I noticed that the hosts get stuck in Connecting state because MS is waiting for a response of the ReadyCommand from the agent. Since we take a lock on connection and disconnection, restarting the agent doesn't work. To fix this, we have to restart the MS or wait for ~1 hour (default timeout).
On the agent side, it gets stuck waiting for a response from the Script execution.
To reproduce, run smoke/test_vm_life_cycle.py (TestSecuredVmMigration test class to be specific). Once the tests are complete, you will notice that some hosts are stuck in Connecting state. And restarting the agent fails due to the named lock. Locks on DB can be checked using the below query.
SELECT *
FROM performance_schema.metadata_locks
INNER JOIN performance_schema.threads ON THREAD_ID = OWNER_THREAD_ID
WHERE PROCESSLIST_ID <> CONNECTION_ID() \G;
This PR adds a wait for the ready command and a timeout to the Script execution to ensure that the thread doesn't get stuck and the named lock from database is released.

This PR makes changes to use cluster's free metrics instead of used while computing imbalance for the cluster. This allows DRS to run for clusters where hosts doesn't have the same amount of metrics.
To prevent errors during multi-user access, use account UUID to create/access user on the provider side. Also, update the existing secret key for a user that already exists.
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.
This PR provides a new primary storage volume type called "FiberChannel" that allows access to volumes connected to hosts over fiber channel connections. It requires Multipath to provide path discovery and failover. Second, the PR adds an AdaptivePrimaryDatastoreProvider that abstracts how volumes are managed/orchestrated from the connector to communicate with the primary storage provider, using a ProviderAdapter interface, allowing the code interacting with the primary storage provider API's to be simpler and have no direct dependencies on Cloudstack code. Lastly, the PR provides an implementation of the ProviderAdapter classes for the HP Enterprise Primera line of storage solutions and the Pure Flash Array line of storage solutions.
Sometimes the hostStats object of the agents becomes null in the management server. It is a rare situation, and we haven't found the root cause yet, but it occurs occasionally in our CloudStack deployments with many hosts.
The hostStat is null, even though the agent is UP and hosting multiple VMs. It is possible to access the VM consoles and execute tasks on them.
This pull request doesn't address the issue directly; rather it displays those hosts in Prometheus so we can restart the agent and get the necessary information.
This PR adds the capability in CloudStack to convert VMware Instances disk(s) to KVM using virt-v2v and import them as CloudStack instances. It enables CloudStack operators to import VMware instances from vSphere into a KVM cluster managed by CloudStack. vSphere/VMware setup might be managed by CloudStack or be a standalone setup.
CloudStack will let the administrator select a VM from an existing VMware vCenter in the CloudStack environment or external vCenter requesting vCenter IP, Datacenter name and credentials.
The migrated VM will be imported as a KVM instance
The migration is done through virt-v2v: https://access.redhat.com/articles/1351473, https://www.ovirt.org/develop/release-management/features/virt/virt-v2v-integration.html
The migration process timeout can be set by the setting convert.instance.process.timeout
Before attempting the virt-v2v migration, CloudStack will create a clone of the source VM on VMware. The clone VM will be removed after the registration process finishes.
CloudStack will delegate the migration action to a KVM host and the host will attempt to migrate the VM invoking virt-v2v. In case the guest OS is not supported then CloudStack will handle the error operation as a failure
The migration process using virt-v2v may not be a fast process
CloudStack will not perform any check about the guest OS compatibility for the virt-v2v library as indicated on: https://access.redhat.com/articles/1351473.
On no access to the storage nodes, we now create a temporary resource from the snapshot and copy that data into the secondary storage. Revert works the same, just that we now also look additionally for any Linstor agent node.
Also enables now backup snapshot by default.
This whole BackupSnapshot functionality was introduced in 4.19,
so I would be happy if this still could be merged.
