VGA, or rather the way it is used in the Linux kernel cannot be
realistically supported on ARM at the moment. But if you want a
graphical display, why not using virtio-gpu?
It works well enough for me, although I do not use libvirt, and stick
to just qemu. For the record, this is the relevant section of my command
line:
-device virtio-gpu-pci -display sdl -device virtio-tablet-pci -device
usb-ehci,id=ehci -device usb-kbd
I've just checked with VNC:
-device virtio-gpu-pci -display vnc=127.0.0.1:0,to=100 -device
virtio-tablet-pci -device usb-ehci,id=ehci -device usb-kbd
and although it is much slower (not surprising), it seems to work just
as well.
Hope this helps,
M.
