Hi Liu,

I don't fully understand what the problem is. Why can't you edit

You shouldn't create a bridge in the frontend at all (at least not for
opennebula), the bridge should be created in the nodes. Keep in mind that
even with a bridge your host/node will not lose its IP.

For instance, in the following setup eth0 is the physical interface and
beth0 is a bridge:

# The primary network interface
auto beth0
iface beth0 inet static
        bridge_ports eth0
        bridge_stp off
        bridge_maxwait 5

As you can see it's configured to bridge the physical interface eth0, so
that VMs can be attached to it by using beth0. Read this document for more
