[Xen-users] Re: bridging two interfaces

["Tomoki Taniguchi" <tomoki.taniguchi@xxxxxxxxx>]

just an update.
Now I am sure my xenbr1 is note being set properly
it is being bridged to eth0
I changed the domU's eth1 settings from
static to dhcp, and eth1 gets an ip from the LAN
which is connected to the eth0 on dom0.

so i guess my multi-network-bridge script is not working properly.
