Hello,
I've some trouble to set up a bridge interface for xen. I don't have
any connexion on the domUs.
There the ifconfig on dom0
% ifconfig

Now on the domU

The result of brctl
% brctl show
bridge name bridge id STP enabled interfaces
xenbr0 8000.00241d83c52e yes eth0
vif1.0
And finally the network/interfaces files for respectively the dom0 and the domU
% cat /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
iface eth0 inet manual
auto xenbr0
iface xenbr0 inet dhcp
bridge-ports eth0
bridge_stp on
bridge_maxwait 0
bridge_fd 0
# cat /etc/network/interfaces
auto lo
iface lo inet loopback
auto eth0
#iface eth0 inet dhcp
iface eth0 inet dhcp
The domU don't have ip address.
Also, here what happens when I try to do ifdown/ifup eth0 on the domU
# ifup eth0
