dom0 also has an eth0:1 which is shared with the remaining six domU's in a
brodcast domain.
After this problem occurs the only way I have found to recover is to reboot,
trying to restart xend has no affect, the domU's start panicing as they no
longer can mount /root. The Dom0 also starts having imer ISR/0: Time went
