Description Arik 2021-06-17 13:49:13 UTC

The virtio-scsi multi-queue scsi is currently boolean - either disabled or enabled, and when it's enabled the number of queues is determined automatically.

This RFE is about enabling the user to specify the desired number of multi-queues (in a similar way to IO threads)

Comment 3 Arik 2021-11-02 12:59:54 UTC

Missing the Ansible Collection part

Comment 4 Saif Abusaleh 2021-11-14 13:38:48 UTC

Ansible collection PR merged: https://github.com/oVirt/ovirt-ansible-collection/pull/373

Comment 6 Tamir 2022-05-01 16:48:23 UTC

Tested the RFE using the tests attached (Polarion) on the following env:

Env:
    - 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.

Related bug: 
    Bug 2080752 - VMs and VM pools that are created from a template are not set with the number of virtio-scsi multi-queue queues from the template.
    Bug 2080755 - VMs that are added when extending a VM pool are set with the template's VirtIO-SCSI Multi Queues instead of the pool's VirtIO-SCSI Multi Queues number.
    Bug 2080758 - Cloning a VM with a different number of virtio-scsi multi-queue queues from the original VM doesn't reflect on the cloned VM.

Changing to VERIFIED.
