[QUESTION]: vhost-user-gpu: Unable to find a satisfying vhost-user-gpu

[Jun Piao]

Hi Marc-André,

I encounter a problem when trying to use vhost-user-gpu as below. And
I'm not familiar to the libvirt code. Could you please help find out
the reason?

# virsh create snap1.xml
error: Failed to create domain from snap1.xml
error: operation failed: Unable to find a satisfying vhost-user-gpu

qemu-4.1.1:
  # ./vhost-user-gpu -v -s /home/vgpu.sock -r /dev/dri/renderD128

libvirt-5.8.0:
    <graphics type='spice' port='5901' tlsPort='5903' autoport='yes'>
      <listen type='socket' socket='/tmp/spice.socket1'/>
      <gl enable='yes' rendernode='/dev/dri/renderD128'/>
    </graphics>
    <video model='virtio'>
      <driver name='vhostuser'/>
      <acceleration accel3d='yes' rendernode='/dev/dri/renderD128'/>
    </video>

thanks,
Jun
