Sander,

I believe, my question is a bit different . I can work with br0 with no problems
for DomUs networking.
Up to 4.0.1 i could define bridge in /etc/xen/xend-config.sxp and get this bridge
reported by "brctl show" , but now i cannot do that. Seems like manual intervention
in Ubuntu /etc/network/interfaces is required.

Boris.

Hello Boris,

Dont the default vif scripts connect to xen_br0 and not br0 ?
I specify a different bridge name in the domU config files vif line with bridge=
