Re: [Xen-users] Cloning VM from Xen

[Benjamin Knoth <knoth@xxxxxxxxxxx>]

Hey Emerson and all,
same problem on boot.
If i start Yast i only find the old network device in the list with old
mac-adress, which i changed in the config. And the network device isn't
available.
If i change the network device on the config to br0, i get the follow
error to start the vm with xm create
Error: Device 1 (vif) could not be connected. Could not find bridge
device br0

But on a other vm the device br0 run.

If i change it to bridge=eth0,model=rtl8139 it starts, but i find only a
loop-back device on ifconfig and in Yast i find only the old network
device with old ip-adess and mac-adress.
I get this errors on boot.
