No. virtio-vga supports higher resolutions just fine once the guest driver is loaded. The video memory is used at boot only, before the guest driver is loaded, and 8MB just for a boot display is more than generous. If your guest has no virtio driver use stdvga instead of running virtio-vga permanently in vga compatibility mode. take care, Gerd
