After I restart the physical server bridges are set up correctly:
# brctl show
bridge name bridge id STP enabled interfaces
virbr0 8000.000000000000 yes
xenbr0 8000.feffffffffff no vif0.0
peth0
xenbr3 8000.feffffffffff no vif0.3
peth3
Unfortunately, this did not solve the problem - I manage to start one VM (connected to both of the bridges), but when I try to start the other one, it just hangs when trying to bring up the second interface (connected to xenbr3) :/
I'm currently completely out of ideas, but I'm not giving up ;)
