https://bugzilla.redhat.com/show_bug.cgi?id=1076098We 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.

The patch [1] that adds this option also adds it for VMWare VGA, can we use that too?

How will this behave with pre-1.1.0 qemu (without the commit mentioned [1])? Will it (a) just skip the parameter or will it (b) error out? In case of (b) this is a regression. Martin P.S.: Some tests in qemuxml2argv would go nicely with such change. [1] 4a1e244eb65c646bdd938d9d137ace42d76c95a7
