Thanks Kevin for the clarification.

When the agent-based mechanism drivers determine if they can bind a port on the compute node they examine the host as well as the vnic_type. This function is what an agent-based mech driver uses: https://github.com/openstack/neutron/blob/dcb43cf85e8764d3167fc307bcd81a80abf09644/neutron/plugins/ml2/drivers/mech_agent.py#L85-L114 On Sat, Jul 23, 2016 at 1:02 PM, Zhou, Bin <Bin_Zhou at comcast.com<mailto:Bin_Zhou at comcast.com>> wrote: 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!
