Hi Paul,<br>
<br>
We are using ESXi in production setup with Neutron networking. ESXi
is compatible with OpenStack and specifically <br>
with neutron networking. You need to add some rules in ovs and for
the same you can refer below link.<br>

<p class="MsoNormal">Is anyone using ESXi in production with
Neutron networking?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">We currently run a production OpenStack
cloud with KVM only using OvS+GRE networking. We’re in the
process of evaluating a number of commercial SDN vendors but
we’re being asked to support ESXi in the really near timeframe
before we’ve had sufficient time to complete an objective
evaluation of all the available vendors who would like to sell
us an SDN solution.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">If anyone is running an OpenStack cloud
that includes ESXi hypervisors but does not rely on a
commercial SDN vendor to make it work I’d love to hear about
it. I’m not eager to bypass the vendor evaluation process and
randomly pick a vendor without an objective and fair
evaluation, but I’m finding it hard to locate any
documentation that indicates that ESXi is compatible with
OpenStack (and specifically Neutron networking) unless you
also select one of the commercial SDN vendors to bridge the
gaps.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">If we could add ESXi nodes to our current
OpenStack zones, even if there were some known functional
shortcomings, it would give us some breathing room on
evaluating SDN vendors in a diligent manner.</p>
