From: Peter Krempa <pkrempa@redhat.com> The capability check in 'qemuValidateDomainDeviceDefVideo' which validates whether a <video> definition with acceleration enabled is possible is only aggregate, thus validates that any '-gl' video backend is available. Since qemu compiles each backend into a separate module it's possible to have an installation where 'virtio-gpu-pci-gl' exist but 'virtio-vga-gl' doesn't and it will not be rejected at validation. The commandline though will generate a device *without* the '-gl' which is ABI incompatible with the counterpart which does have '-gl', but the VM starts. If such a VM is then migrated to a deployment which does have the '-gl' variant available, migration will fail because qemu will generate the '-gl' device as we don't record this fact in the XML. This test case captures this situation which will be fixed later.
