Hi guys.

I'm trying to get some video hw acceleration in qemu-kvm-core-10.1.0 + libvirt-libs-11.9.0 + 6.12.63-1.el9.x86_64, but I can only start guests with:
...
    <video>
      <model type='virtio' heads='1' primary='yes'>
      </model>
      <driver name='qemu'/>
      <alias name='video0'/>
      <address type='pci' domain='0x0000' bus='0x00' slot='0x01' function='0x0'/>
    </video>
...
if I use:
        <acceleration rendernode='/dev/dri/by-path/pci-0000:04:00.0-render'/>
then qemu fails with:
        virtqemud[4922]: unsupported configuration: unsupported rendernode accel attribute without 'vhostuser'
when do add:
      <driver name='vhostuser'/>
then:
      virtqemud[4922]: unsupported configuration: this QEMU does not support 'vhost-user' video device
with:
      <driver name='qemu'/>
Qemu also fails.

This is a bit - if not entirely - nonsensical, is it not? Am I missing some crucial bits?

Is the issue steaming from Qemu/build - and if yes then, can building Qemu with some(what?) flags, fix it? - or is this rather hardware side of things most likely the root cause?

many thanks, L.
