Hi, Everyone After I installed the dom0 and domU, I found one thing that make me much confused. [root@node1 ~]# brctl show bridge name bridge id STP enabled interfaces virbr0 8000.000000000000 yes xenbr0 8000.feffffffffff no vif42.0 peth0 vif0.0 xenbr1 8000.feffffffffff no vif42.1 peth1 vif0.1 xenbr2 8000.feffffffffff no vif42.2 peth2 vif0.2 All bridges have the same bridge id: 8000.feffffffffff. I don''t konw if it is normal or bad. Can anyone help me figure it out.
