Hello,

I've tried the same here but didn't come as far as you did. How did you get
xenbr1 connected with peth1?

If I run

# /etc/xen/scripts/network-bridge start vifnum=1 bridge=xenbr1 netdev=eth1

the second bridge isn't set up correctly.

# brctl show
bridge name     bridge id               STP enabled     interfaces
xenbr0          8000.feffffffffff       no              vif0.0
                                                        peth0
                                                        vif1.0
xenbr1          8000.000000000000       no
