Hi, I'm setting up my first xen machine, and I'm trying to setup two Virtual Machines, each mapped to a physical adapter on a different network.

The virtual machine mapped to xen-br0 and eth0 works fine. However, when I bring up a VM with this configuration file:

-----------------
name = "test77"
kernel = "/boot/vmlinuz-2.6.11.12-xenU"
root = "/dev/hda1"
memory = 64
disk = ['file:/vserver/images/vmPROD.img,hda1,w','file:/vserver/images/vmPROD-swap.img,hda2,w']

#Network:
nics=1
dhcp="off"
ip="192.168.1.80"
netmask="255.255.255.0"
gateway="192.168.1.1"
hostname="jidoorPROD"
vif=[ 'bridge=xen-br1' ]

extra="3"
-----------------

On the VM my ifconfig for eth0 looks correct:
-----------------
eth0      Link encap:Ethernet HWaddr AA:00:00:65:9A:F0
          inet addr:192.168.1.80  Bcase:192.168.1.255  Mask:255.255.255.0
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:31 errors:0 dropped:0 overruns:0 frame:0
          TX packets:110 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:2136 (2.0 KiB)  TX bytes:9396 (9.1KiB)
-----------------

"brctl show" on the DOM0 HOST shows the xen-br1 bridge connected to eth1 like it should be:
-----------------
xen-br1       8000.0012175a875c    no       eth1
-----------------

I'm able to get outside name resolution from the DOM0 Host, and my routing table looks like this:

>From "netstat -r"
-----------------
192.168.1.0    *                255.255.255.0     U      0 0          0   xen-br1
default        192.168.1.1      0.0.0.0           UG     0 0          0   xen-br1
-----------------

I created the bridge using
-----------------
/etc/xen/scripts network start antispoof=no bridge=xen-br1 netdev=eth1
-----------------

I'm running Debian Sarge for both the DOM0 and DOMU's, and as I said, it works off of xen-br0 on the other network.

If you can think of any other information relevant to this, let me know and I'll be happy to send it on. Any help is greatly appreciated, I've been working on this for several days now and can't for the life of me figure this out.
