Xen network-route AND network-bridge setup
Hey guys,

I've currently got a Xen box with 3 Virtual machines on it, in a routed setup. I'd like to put them all on a private internal network as well, which I'm assuming I'd do with a dummy network card and a xen bridge, but I can't find any information about setting up the xen Bridging setup on top of the existing network-route instlal.

Is it possible to do this?

I have a similar setup. The only difference is that I already have a network-bridge on the real network and I added a private net as well.

First you need to create the dummy bridge on the dom0 (I call it dmzbr0):

# brctl show
bridge name        bridge id                STP enabled        interfaces
dmzbr                8000.feffffffffff        no                vif1.1

And then you add new network adapters to the domU's and attach them to the bridge:

#  Networking
dhcp        = 'dhcp'
vif        = [ 'mac=00:12:34:56:78:90,bridge=eth0', 'mac=00:AB:CD:EF:01:23,bridge=dmzbr' ]

And I guess you'll handle it from here on. If not, ask :)
