Jianlin,
While I wrote the libvirt->vmchannel glue, I'm not actually that
familiar with vmchannel itself. I've cc'd Amit, who hopefully might
recognise this problem and tell me how to fix it ;)
Amit,
Any idea what's going on here?
Yes:

virtio-serial-pci,id=virtio-serial0,max_ports=0,vectors=0,bus=pci.0,addr=0x5: Device
'virtio-serial-pci' could not be initialized
With max_ports=0, the virtio-serial device doesn't get created and hence
this error.
