libvirt XML error: device type video not supported (Ignore or support)

[tunicashashi]

I tried to run a VM on ACRN hypervisior compute node using Devstack controller but fails as compute node libvirt XML is not parsed completely. It is because of device type video not supported.

I have installead acrn hypervisior and acrn-libvirt on my compute node. I can see node and hypervisor type when I list in the openstack controller.

• Is there any way to ignore from acrn-libvirt or better will be to provide support for it?
  If i can ignore which src code can I change with what parameter?

Video devices are currently unsupported by the ACRN driver. If you can configure OpenStack to not use the video device, that would be our recommendation.
