virtio-vga doesn't need dedicated video memory, except for the
(unaccelerated) vga compatibility mode.  But given that there are no
virtio-vga drivers for windows (yet) it'll actually runs in vga mode, so
you have no advantages over stdvga.

stdvga can be configured with up to 256M of video memory (-device
VGA,vgamem_mb=3D64).  This will allow higher resolutions display
resolutions.  Still an unaccelerated framebuffer though.

cheers,
