Add the network NET to the virtual machine DOMAIN. Networks are always addded to the end of the current list of networks in the virtual machine.
NET may be a PVC network VNI, which is added as a bridged device, or a SR-IOV VF device connected in the given mode.
NOTE: Adding a SR-IOV network device in the "hostdev" mode has the following caveats:
1. The VM will not be able to be live migrated; it must be shut down to migrate between nodes. The VM metadata will be updated to force this.
2. If an identical SR-IOV VF device is not present on the target node, post-migration startup will fail. It may be prudent to use a node limit here.
