Hi, You may or may not be aware of the vlan-aware-vms effort [1] in Neutron. If not, there is a spec and a fair number of patches in progress for this. Essentially, the goal is to allow a VM to connect to multiple Neutron networks by tagging traffic on a single port with VLAN tags.
This effort will have some effect on vif plugging because the datapath will include some changes that will effect how vif plugging is done today. The design proposal for trunk ports with OVS adds a new bridge for each trunk port. This bridge will demux the traffic and then connect to br-int with patch ports for each of the networks. Rawlin Peters has some ideas for expanding the vif capability to include this wiring. There is also a proposal for connecting to linux bridges by using kernel vlan interfaces. This effort is pretty important to Neutron in the Newton timeframe. I wanted to send this out to start rounding up the reviewers and other participants we need to see how we can start putting together a plan for nova integration of this feature (via os-vif?).
