[libvirt] [PATCH] qemu: Pass the number of heads even with -vga qxl
When added in multiple previous commits, it was used only with -device qxl(-vga), but for some QEMUs (< 1.6) we need to add this functionality when using -vga qxl as well.

I would expect a qemuBuild.*Command function to build the command line, not alter the domain definition. Also, this goes against commit ef11e770 qemu_command: don't modify heads for graphics device Jan

I, actually think that patch should've not made it in, but I must've missed that it was posted. The setting merely updates the XML so that it is visible whether or not the setting was applied. It then also works when migrating to a newer qemu, so that it doesn't reset the limitation. But I'll leave this to other time and will post a v2 without that.
