Message-ID: <f27113ac4b180f85d92ba96c6e2b0065983945da.1784297532.git.jdenemar@redhat.com>
From: Peter Krempa <pkrempa@redhat.com>

Subject: [PATCH] qemuxmlconftest: Add test cases for configs asking for
'virtio-gpu-gl' or 'virtio-vga-gl' without the capability
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.
