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:<br>
SR-IOV port doesn’t reach OVS port on same compute node: <a href="https://bugs.launchpad.net/neutron/+bug/1492228" rel="noreferrer" target="_blank">
https://bugs.launchpad.net/neutron/+bug/1492228</a><br>
No connectivity when Launching an instance with Openvswitch interface when using SR-IOV:

Can anyone kindly help me to clarify it? Thanks a lot!<br>
