This PR introduces the functionality of purging removed DB entries for CloudStack entities (currently only for VirtualMachine). There would be three mechanisms for purging removed resources:
Background task - CloudStack will run a background task which runs at a defined interval. Other parameters for this task can be controlled with new global settings.
API - New admin-only API purgeExpungedResources. It will allow passing the following parameters - resourcetype, batchsize, startdate, enddate. Currently, API is not supported in the UI.
Config for service offering. Service offerings can be created with purgeresources parameter which would allow purging resources immediately on expunge.
Following new global settings have been added:
expunged.resources.purge.enabled: Default: false. Whether to run a background task to purge the expunged resources
expunged.resources.purge.resources: Default: (empty). A comma-separated list of resource types that will be considered by the background task to purge the expunged resources. Currently only VirtualMachine is supported. An empty "value will result in considering all resource types for purging
expunged.resources.purge.interval: Default: 86400. Interval (in seconds) for the background task to purge the expunged resources
expunged.resources.purge.delay: Default: 300. Initial delay (in seconds) to start the background task to purge the expunged resources task.
expunged.resources.purge.batch.size: Default: 50. Batch size to be used during expunged resources purging.
expunged.resources.purge.start.time: Default: (empty). Start time to be used by the background task to purge the expunged resources. Use format yyyy-MM-dd or yyyy-MM-dd HH:mm:ss.
expunged.resources.purge.keep.past.days: Default: 30. The number of days in the past from the execution time of the background task to purge the expunged resources for which the expunged resources must not be purged. To enable purging expunged resource till the execution of the background task, set the value to zero.
expunged.resource.purge.job.delay: Default: 180. Delay (in seconds) to execute the purging of an expunged resource initiated by the configuration in the offering. Minimum value should be 180 seconds and if a lower value is set then the minimum value will be used.

Feature spec: https://cwiki.apache.org/confluence/display/CLOUDSTACK/Granular+Resource+Limit+Management
Introduces the concept of tagged resource limits for granular resource limit management. Limits can be enforced on accounts and domains for the deployment of entities for a tagged resource. Current tagged resource limits can be used for the following resource types,
Host limits
- user_vm
- cpu
- memory
Storage limits
- volume
- primary_storage
Following global settings can used to specify tags for which limit needs to be enforced,
Host: `resource.limit.host.tags`
Storage: `resource.limit.storage.tags`
Option for specifying tagged resource limits and viewing tagged resource usage are made available in the UI.

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 moves resources stuck in transition state during async job cleanup
Problem:
During maintenance of the management server, other servers in the cluster or the same server after a restart initiate async job cleanup. However, this process leaves resources in a transitional state. The only recovery option currently available is to make direct database changes.
Solution:
This PR introduces a resolution by changing Volume, Virtual Machine, and Network resources from their transitional states. This adjustment enables the reattempt of failed operations without the need for manual database modifications.
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)
#8433 (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 fixes reorder/list pools when cluster details are not set, while deploying vm / attaching volume.
Problem:
Attach volume to a VM fails, on infra with zone-wide pools & vm.allocation.algorithm=userdispersing as the cluster details are not set (passed as null) while reordering / listing pools by volumes.
Solution:
Ignore cluster details when not set, while reordering / listing pools by volumes.
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 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.
Observed a failure to start new virtual machine with PowerFlex storage. Traced it to concurrent VM starts using the same template and the same host to copy. Second mapping attempt failed.
While creating the volume clone from the seeded template in primary storage, adding a lock with the string containing IDs of template, storage pool and destination host avoids the situation of concurrent mapping attempts with the same host.
This PR adds new functionality to copy snapshots across zones and take snapshots for multiple zones.
Copy functionality is similar to template copy. The source zone acts as the web server from where the destination zone(s) can download the snapshot files. For this purpose, a new API - `copySnapshot` has been added. The response for copySnapshot will be returning zone and download details from the first destination zone of the request. This behaviour is similar to the `copyTemplate` API.
In a similar manner, multiple zones can be selected while taking the snapshots or creating snapshot policies. For this snapshot will be taken in the base zone(in which volume is present) and then copied to the additional zones. A new parameter - `zoneids` has been added to `createSnapshot` and `createSnapshotPolicy` APIs.
As snapshots can be present on multiple zones (secondary stores), a new parameter `zoneid` has been added to delete the snapshot copy on a specific zone.
`listSnapshots` API has been updated to allow listing snapshot entries for different zones/datastores. New parameters - `showUnique`, `locationType` have been added.
Events generated during snapshot operations will now be linked to the snapshot itself rather than the volume of the snapshot.
`listSnapshotPolicies` and `createSnapshotPolicy` APIs will return zone details of the zones in which backup will be scheduled for the policy.
