Re: [Xen-users] Help me to set up network (routes)

Ok. I found more better solution. It's called Bridging+NAT.
So, a small tutorial.
1) With methods of your OS create a dummy (empty) bridge: br0 (setup its
options).
2) Set up IP for bridge. (For example, 10.0.2.1)
2) Edit /etc/xen/xend-config.sxp:
(network-script /bin/true)
(vif-script vif-bridge)
3) Edit your VM configuration file:
vif = [ 'bridge=br0' ] # it's the bridge, which we created in step 1
4) Load DomU. Change DomU network configuration:
IP: Any IP in network specied in step 2 (for example, 10.0.2.2)
Mask: Mask from step 2 (for example, 255.255.255.0)
Gateway: Bridge from step 1 IP (for example, 10.0.2.1)
5) In Dom0 apply 2 iptables rules (kernel must be compiled with NAT
support):
iptables -t nat -A POSTROUTING -s <IP FROM STEP 4> -j MASQUERADE
iptables -t nat -A POSTROUTING -d <IP FROM STEP 4> -o <BRIDGE FROM
STEP 1>
6) Start DomU
That's all. Dom0 accessed from DomU via Bridge IP (step 2). DomU
accessed from Dom0 via DomU IP (STEP 4).
Everything must work at this point ;-)
