Do you have a bridge configured? What is the output of "brctl show" and
"ifconfig -a" while the guest is running?

It seems to have waited for the backend to hit state 2, which happens,
and then it has failed for some reason, which I can't see here. It might
be worth adding some debug to the vif hotplug script to see if it is
running at all.

Are you using the vif script's from Xen 4.4? Perhaps you have got some
stale 4.3.1 scripts sitting around?

Ian.
