Re: [libvirt] [PATCH] properly set video ram size for qemu VGA video device

https://bugzilla.redhat.com/show_bug.cgi?id=1076098 We support vram option for video devices in domain xml, but so far only for QXL it had some effect. VGA video device in QEMU can also accept the size of video ram and we should pass it.
