Hi,

This series adds support for running virtio GPUs in seperate processes, thanks to vhost-user backend.

Some quick notes. I attempted to run this with fedora 31 qemu. The qemu provided 50-qemu-gpu.json needs the trailing comma removed or libvirt fails to parse it. I sent a qemu-devel patch to fix that. If model type='virtio' without driver name='vhostuser', VM startup crashes libvirt at: qemuSetupDevicesCgroup (vm=0x7fff9838b160) at qemu/qemu_cgroup.c:826 if (qemuSetupVideoAccelCgroup(vm, vm->def->videos[i]->accel) < 0) I didn't look into it any more than that. I will check more tomorrow Thanks, Cole
