Can Neutron support multiple mechanism drivers on the same compute node? I thought the answer was “no”. But I start to doubt when I read configuration guide about SR-IOV driver. Particularly the following bugs: SR-IOV port doesn’t reach OVS port on same compute node: https://bugs.launchpad.net/neutron/+bug/1492228 No connectivity when Launching an instance with Openvswitch interface when using SR-IOV: https://bugzilla.redhat.com/show_bug.cgi?id=1174864 Can anyone kindly help me to clarify it? Thanks a lot! Bin Zhou
