Before the wall of code I'll explain the situation. I'm trying to set up two interfaces to be teamed together, and from that team create a bridge.
I've been studying for the RHCE and I believe this type of situation might be on the test so I've been trying to get it down, however in all of my testing I've not been able to get this to work properly. At the end of the set up, the bridge appears to be there, however there is no IP assigned to it, and it is unable to ping the gateway.
The test environments are vm's in kvm and I've been using internal networks.
