Hi,

I just tried to migrate a VM from one machine to another.

The basics work - after a "xm migrate <VM> <destination> - the VM is up and running on the 2nd machine.

But... the network port doesn't come up. Trying an ifup eth0, or even a /etc/init.d/networking/restart, gives the following (virtual) console error:

test_2:/home/milesf# /etc/init.d/networking restart
Reconfiguring network interfaces...milesf[1667]: ERROR: Interface eth0 does not seem to be present in the system
SIOCSIFADDR: No such device
eth0: ERROR while getting interface flags: No such device
SIOCSIFNETMASK: No such device
SIOCSIFBRDADDR: No such device
eth0: ERROR while getting interface flags: No such device
eth0: ERROR while getting interface flags: No such device
Failed to bring up eth0.

The only way to get networking back up is to reboot the VM.

Any ideas?

Thanks,

Miles Fidelman
