Hi, Based on the virtio-1.0 spec, the virtio pci devices' layout have been changed, such as PCI_SUBSYSTEM_ID and modern_mem_bar.
But the current qtest still don't support the virtio-1.0 or later devices. Such as virtio-gpu, Virtio-input and virtio-crypto devices. Refer to functions in tests/libqos/virtio-pci.c. Any plans to support them? Thanks! Regards, -Gonglei
