Hi! I think unless you use "-vga none" or "-nodefaults", QEMU will always start your guest with a VGA card by default, so if you add an additional "--device virtio-gpu-pci", you'll end up with a guest that has two video cards, one VGA and one virtio-gpu. Also there is a known bug in the SLOF version that has been shipped with QEMU 2.8, which causes trouble with virtio-gpu: http://git.qemu-project.org/?p=SLOF.git;a=commitdiff;h=38bf852e73ce6f0ac801dfe8ef1545c4cd0b5ddb Please try again with the latest release candidate of QEMU 2.9, it should be fixed there. (But please note that SLOF does not contain a driver for virtio-gpu, so you won't see any output from the firmware when starting your guest ... i.e. you'll just see some output once Linux has been started)
