Description Tamir 2022-05-01 16:30:35 UTC 
Description of problem:

When cloning a VM and changing the custom number of virtio-scsi multi-queue queues, the VM is created with the custom number of virtio-scsi multi-queue queues from the original VM, instead of the number that was provided in the clone modal.

Version-Release number of selected component (if applicable):
    - Engine instance with RHV 4.5.0-8 (ovirt-engine-4.5.0.5-0.7.el8ev) and RHEL 8.6 installed.
    - 3 hosts with RHV 4.5.0-8 and RHEL 8.6 and with vdsm-4.50.0.13-1.el8ev.

How reproducible:
100%

Steps to Reproduce:
1. Create a 4.7 data center and a 4.7 cluster.
2. Install the hosts and create a new NFS storage domain.
3. Create an RHEL VM with VirtIO-SCSI Multi Queues set to Custom and 3 queues.
4. Clone the VM with VirtIO-SCSI Multi Queues set to Custom and 2 queues.
5. Check that the created VM's VirtIO-SCSI Multi-Queues is set to Custom, and the number of the queues is set to 2.

Actual results:
1. The 4.7 data center and the 4.7 cluster were created.
2. The hosts were installed and the NFS storage domain was created.
3. The VM was created with VirtIO-SCSI Multi Queues set to Custom and 3 queues.
4. The VM was cloned.
5. The created VM is set with VirtIO-SCSI Multi Queues set to Custom and 3  queues.

Expected results:
Steps 1-4 results are as expected. 
In step 5, the cloned VM should have VirtIO-SCSI Multi Queues set to Custom, and the number of queues should be set to 2.
Comment 1 Tamir 2022-06-07 13:57:12 UTC 
Verified on RHV 4.5.1-1.

Env:
    - Engine instance with RHV 4.5.1-1 (ovirt-engine-4.5.1-0.62.el8ev) and RHEL 8.6 installed.
    - 2 hosts with RHV 4.5.1-1 and RHEL 8.6 and with vdsm-4.50.1.1-1.el8ev.


Steps:

In Admin Portal:
1. Create a 4.7 data center and a 4.7 cluster.
2. Install the hosts and create a new NFS storage domain.
3. Create an RHEL VM with VirtIO-SCSI Multi Queues set to Custom and 3 queues.
4. Clone the VM with VirtIO-SCSI Multi Queues set to Custom and 2 queues.
5. Check that the created VM's VirtIO-SCSI Multi-Queues is set to Custom, and the number of the queues is set to 2.

Results (As Expected):
1. The 4.7 data center and the 4.7 cluster were created.
2. The hosts were installed and the NFS storage domain was created.
3. The VM was created with VirtIO-SCSI Multi Queues set to Custom and 3 queues.
4. The VM was cloned.
5. The created VM is set with VirtIO-SCSI Multi Queues set to Custom and 2 queues.
