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. ChangeLog -------- v1 -> v2 - remove error_propagate (patch 2) - Add byteswap functions (patch 1) - Handle endian conversion for virtio_gpu_ctrl_response (patch 1) v2 -> v3 - updated patch 1 based on Gerd's feedback - rename bswap functions (patch 1) - use in-place swapping functions (patch 1) - Handle endian conversion for cursor update (patch 1) Thank you Farhan Farhan Ali (2): virtio-gpu: Handle endian conversion virtio-gpu-ccw: Create a virtio gpu device for the ccw bus hw/display/virtio-gpu.c | 70 +++++++++++++++++++++++++++++++++++++++++++------ hw/s390x/virtio-ccw.c | 49 ++++++++++++++++++++++++++++++++++ hw/s390x/virtio-ccw.h | 10 +++++++ 3 files changed, 121 insertions(+), 8 deletions(-) -- 1.9.1
