XenServer already support OVS native mode and I have a patch for
configuring it https://review.openstack.org/#/c/372952/ which
is fine. But we have another patch which revert the usage of
ml2_confi.ini and ml2_conf.ini.domU
https://review.openstack.org/#/c/396573/. Both patches work well
separately. But the two should have some dependent relationship.
Once one merged, the other should change accordingly. Sorry that
we missed the dependency.
This patch is to fix the ovs config based on reverted ml2_conf.ini
and ml2_conf.ini.domU to make sure we configure the correct IP for
ovs agent
