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.
* Update overcommit ratio during live VM migration
* minor refactoring

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 API `purgeExpungedResources`. It will allow passing the following parameters - resourcetype, batchsize, startdate, enddate
- 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 DB records of 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 DB records of 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 DB records of the expunged resources.
- `expunged.resources.purge.delay`: Default: 300. Initial delay (in seconds) to start the background task to purge the DB records of the expunged resources task.
- `expunged.resources.purge.batch.size`: Default: 50. Batch size to be used during purging of the DB records of the expunged resources.
- `expunged.resources.purge.start.time`: Default: (empty). Start time to be used by the background task to purge the DB records of 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 DB records of the expunged resources for which the expunged resources must not be purged. To enable purging DB records of the 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 the DB records 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.

This refactors a ResourceManager::listAvailHypervisorInZone method
that should return unique hypervisors for which existing hosts are Up
and processed. We can approximate this by assuming that those hosts
would have setup their hypervisor-specific systemvmtemplates. In a given
environment there wouldn't be thousands of systemvmtemplates, but can
have thousands of hosts. So, instead of scanning the entire cloud.host
table, we can make calculate guess by returning unique hypervisors of
systemvm templates which are ready. This method was used in
::processConnect() when an agent joins, to speed up its handling.

* Fix host stuck in connecting state (#8502)
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.
* Externalise a few timeouts & fix timeout for hostSupportsUefi in libvirt ready command wrapper (#8547)
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 fix ensures when datastore cluster in VMware is added as a primary storage pool in CloudStack then all the child datastores (which already exists in CS) should be in Up state.
For example:
1. Datastore Cluster DS has two child datastores A and B in vCenter. (B is already added as a storage pool in CloudStack)
2. Now try to add datastore cluster DS into CloudStack as a primary storage pool
3. CloudStack tries to add child datastores A and B in CloudStack, since B is already there in CloudStack, it will reuse the existing storagepool entry and will keep under parent Storage pool DS.
During Step 3 we are now checking if B is Up state or not.
The alert.email.addresses description is ambiguous and can cause doubts to operators. This description has been altered to avoid confusion. In addition, typos in alert.smtp.useStartTLS and project.smtp.useStartTLS have been fixed.

Currently, our compute offerings and disk offerings are tightly coupled with respect to many aspects. For example, if a compute offering is created, a corresponding disk offering entry is also created with the same ID as the reference. Also creating compute offering takes few disk-related parameters which anyway goes to the corresponding disk offering only. I think this design was initially made to address compute offering for the root volume created from a template. Also changing the offering of a volume is tightly coupled with storage tags and has to be done in different APIs either migrateVolume or resizeVolume. Changing of disk offering should be seamless and should consider new storage tags, new size and place the volume in appropriate state as defined in disk offering.
