Public bug reported:

The commit
https://github.com/openstack/neutron/commit/05a54e800430bcfc81e36e1dad89fa47f3e8a6f0
appears to break XenServer integration.

Specifically,
https://github.com/openstack/neutron/commit/05a54e800430bcfc81e36e1dad89fa47f3e8a6f0
#diff-6a3c59b7b71c12cc29eca4c85268864eR1348 appears to run exclusively
in the context of Nova - however in XenServer, the IP address for the
tunnel is in dom0.  XenServer's agent will redirect the actual OVS
command to dom0 so the local IP address check is not valid.

We therefore fail with ERROR
neutron.plugins.ml2.drivers.openvswitch.agent.ovs_neutron_agent [-]
Tunneling can't be enabled with invalid local_ip '10.62.65.37'. IP
couldn't be found on this host's interfaces.

** Affects: neutron
     Importance: Undecided
         Status: New
