How does OpenNebula handle this? I want to redo my hosts and start fresh. Do I need to go ahead and do the bond/trunk on the host manually or does OpenNebula handle that?

In other words, OpenNebula doesn't handle the network configuration, you have to do that manually, it only cares about what bridge to hook the VMs to.
