For the S390 architecture which does not natively support any graphics device, virtio gpu in 2D mode could be used to emulate a simple graphics card and use VNC as the display. eg: qemu-system-s390x ... -device virtio-gpu-ccw,devno=fe.0.0101 -vnc host_ip_addr:5900 Note, to actually see any display content the guest kernel needs to support DRM layer, Virtio GPU driver, the Virtual Terminal layer etc. I would appreciate any feedback on these patches, specially the first patch.
