A short note on bridges and how they are used in Oracle VM Manager and server
OnOracle VM server, at boot time, we create a bridge for each physical adaptor that is present in the system:
if you have eth0,1,2 you will get bridges named xenbr0, xenbr1,xenbr2
so for each ethXX there is xenbrXX
When you create a virtual machine, you need to tell the system which physical network the virtual interface can use. The virtual interface (vif) needs to be bound to a bridge.Oracle VM manager queries the bridge names from the Oracle VM server through the agent and gives you a list to pick from. This list then just contains the xenbrXX names.
if you want to know where they are bound, you can look at the local console of the Oracle VM server and it will tell you which bridge is attached to which eth and also the mac address so you can find out which physical port. or you can do cat /etc/issue or you can run ifconfig commands or brctl show and so forth.
In the future we intend to make it possible to name your own bridges so that its more clear instead of using just xenbrXX.
