Some output from the dom0 if its of any use:

Hi,

Is it possible to configure a domU with multiple IP addresses?

i.e. (v)eth0 and (v)eth0:0, or (v)eth0 and lo:0

I can add the additional interface in the domU just fine so that it shows up in ifconfig, but the bridge doesn't seem to do its magic to make it accessible.

vif = [ 'bridge=xenbr0', 'bridge=xenbr0' ]

The docs tend to indicate that vifx.1 will always go to (v)eth1, but unfortunately I can't get the bridge to do (v)eth1 either :(

Thanks in advance,

Roger
