Ian,

	assuming you want to add that to a second
interface, you need to create a second bridge. See the
config file parts below.

Sincerely,

Jan.

==========================================/etc/xen/xend-config.sxp:
==========================================
(network-script ''my-network-bridge'')

==========================================/etc/xen/scripts/my-network-bridge:
==========================================
#!/bin/sh
# start bridges on both eth0 and eth1

XENDIR="/etc/xen/scripts"

$XENDIR/network-bridge "$@" netdev=eth0 bridge=xenbr0 vifnum=0
$XENDIR/network-bridge "$@" netdev=eth1 bridge=xenbr1 vifnum=1

==========================================vm1.cfg:
==========================================
...
vif = [ ''mac=aa:00:01:00:10:08,bridge=xenbr0'',
''mac=aa:00:01:00:10:07,bridge=xenbr1'' ]
dhcp    = "off"
...

Why a second bridge? It depends on what he wants to do with these
interfaces and his network setup if he needs an additional bridge or
other stuff, like routing.
Just the addition vif in the vm config (attached to the same bridge as
the other interfaces should be enough.

Just a second IP address can be done with an alias, even on eth0, but
that''s linux networking basics...
