Hi qemu developer,
I have a question that does qume support cname as host to attach rbd device?
When I want to do that, it return a error:
/# virsh attach-device virtlet-228fa0ac-d53a-tess-node-c7nww disk_vde.yaml
error: Failed to attach device from disk_vde.yaml
error: internal error: unable to execute QEMU command 'device_add': Property 'virtio-blk-device.drive' can't find value 'drive-virtio-disk20'

/# cat disk_vde.yaml

Could you tell me whether qemu supoort this? If yes, which version? IF no, do you any plan for this?

Thanks,
Tao
