[Xen-devel] Device 0 couldnt be connected

[Jun Koi <junkoi2004@xxxxxxxxx>]

hi,

I am trying to use latest stage tree (C/S 19806), but got error like:

"Error: Device 0 (vif) could not be connected. Hotplug scripts not working."

The qemu log doesnt say much about problem, like below. Any idea?

Thanks,
J
