Hi,

The whole list is:
  name "virtio-blk-pci", bus PCI, alias "virtio-blk"
  name "virtio-scsi-pci", bus PCI
  name "virtio-net-pci", bus PCI, alias "virtio-net"
  name "virtio-input-host-pci", bus PCI
  name "virtio-keyboard-pci", bus PCI
  name "virtio-mouse-pci", bus PCI
  name "virtio-serial-pci", bus PCI, alias "virtio-serial"
  name "virtio-tablet-pci", bus PCI
  name "virtio-gpu-pci", bus PCI
  name "virtio-balloon-pci", bus PCI, alias "virtio-balloon"
  name "virtio-rng-pci", bus PCI


HW_COMPAT_2_3 has:
   - virtio-blk-pci
   - virtio-balloon-pci
   - virtio-serial-pci
   - virtio-9p-pci
   - virtio-rng-pci

You mentioned:
   - virtio-scsi-pci
   - virtio-net-pci

I guess the remaining list is:
  - virtio-input-host-pci
  - virtio-keyboard-pci
  - virtio-mouse-pci
  - virtio-tablet-pci
  - virtio-gpu-pci

I don't know if is is applicable to them, or if they have it defaulted to any_layout,
however the above devices are part of QEMU 2.3.


Thanks,
Marcel
