[Xen-users] After migration: network-device of dom0 lost?!

["Rustedt, Florian" <Florian.Rustedt@xxxxxxxxxxx>]

Hello list,

I am migrating a domU from dom0: XEN0 to Ddom0: XEN1. Both are connected via 
eth1, both are connected to the net via (p)eth0.
While doing this, my ssh-connection to the domU keeps running well.

After about a minute, i get a "remote host closed the connection".
If i try to log into host domU or XEN1 then via ssh, i get a "connection timed 
out".

If i then check the logs locally on XEN1, there's nothing special in them.

On XEN1 i have no network any more except the eth1 connection to XEN0. I even 
can't ping the gateway in the same subnet!! 

Checking ifconfig, route and resolv.conf doesn't help either, they are all the 
same as before the error, pretending all is ok. Dmesg is clean. The logs are 
clean, as told before.

If i try to restart networking, i get an error telling me, that network device 
eth0 does not exist?!? After that, dmesg hasn't got any additionally entries...

What could that be? What could have destroyed my (p)eth0 shortly after 
migrating?

Cheers, Florian
