Hello.

I have installed Windows XP as HVM guest and I cannot get the network working. I want Xen to use vlan 15 (10.3.0.1/24) as the base interface on which bridge will be based on. Problem is, the tap0 device isn't passing the traffic to the bridge.
Pinging from Windows guest to Dom0:
nanoha scripts # tcpdump -vvv -i tap0

I have modifed /etc/xen/xend-config.sxp to include following line:
(network-script 'network-bridge netdev=vlan15')
And my /etc/xen/genxp1 is following:
