bridge name     bridge id               STP enabled     interfaces
xenbr0          8000.feffffffffff       no              vif0.0
                                                        peth1

I'd be consistent with the output of ifconfig which I put below in the
same e-mail :-)

I try this configuration, but I don't see up both peth and vif0.0
interfaces:

brctl show
bridge name     bridge id               STP enabled     interfaces
xenbr0          8000.000000000000       no
