[Qemu-devel] aarch64: -device virtio-scsi-device, id=scsi: No 'virtio-bus' bus found for device 'virtio-scsi-device'

[Richard W.M. Jones]

Does anyone have any thoughts on what I'm missing / doing wrong here?

qemu-system-aarch64: -device virtio-scsi-device,id=scsi: No 'virtio-bus' bus 
found for device 'virtio-scsi-device'

qemu: Upstream from git yesterday
kernel: 3.13.0-0.rc7
Hardware: real aarch64(!)

I also tried adding `-device virtio-bus' to the command line, but that
just changes the error message to:

qemu-system-aarch64: -device virtio-bus: 'virtio-bus' is not a valid device 
model name

Also:
