RFE: virt-install qemu:override support

[tinsjourney]

Distro: RHEL 9.2
qemu version: 7.2.0
libvirt version: 9.0.0
virt-install version: 4.1.0

When trying to pass options to specific device (set rotational_rate to scsi or sata disk) we used

--qemu-commandline='device.scsi0-0-0-1.rotation_rate=1'

resulting in adding to the xml file :

  <qemu:commandline>
    <qemu:arg value='-set'/>
    <qemu:arg value='device.scsi0-0-0-1.rotation_rate=1'/>
  </qemu:commandline>

Since libvirt introduced a new XML syntax for overriding device properties (https://libvirt.org/drvqemu.html#overriding-properties-of-qemu-devices), the previous qemu:commandline block is not working anymore we need to use :

  <qemu:override>
    <qemu:device alias='scsi0-0-0-1'>
      <qemu:frontend>
        <qemu:property name='rotation_rate' type='unsigned' value='1'/>
      </qemu:frontend>
    </qemu:device>
  </qemu:override>

Perhaps this is effective?
