Re: [libvirt] [PATCH] qemu: handle not supported writable devices

If the running VM contains a writable raw image, creating snapshot fails internally in QEMU, but the error is not detected by libvirt. Success is still reported to the user, who will see the snapshot in libvirt, even they are NOT created by qemu.
