<p class="MsoNormal">Hi ,<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">How to integrate a physical appliance into the virtual OpenStack infrastructure (with L2 population)? Can you please point me to any relevant material.<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">We want to add the capability to “properly” schedule the port on the physical appliance, so that the rest of the virtual infrastructure knows that a new port is scheduled in the
physical appliance. How to do this?<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">We manage the appliance through a middleware. Today, when it creates a neutron port, that is to be hosted on the physical appliance, the port is dangling. Meaning, the virtual
infrastructure does not know where this port is hosted/implemented. How to fix this?<u></u><u></u></p>
<p class="MsoNormal"> <u></u><u></u></p>
<p class="MsoNormal">Also, we want the physical appliance plugged into L2 population mechanism. Looks like the L2 population driver is distributing L2 info to all virtual infrastructure nodes where
a neutron agent is running. Can we leverage this framework? We don’t want to run the neutron agent in the physical appliance, can it run in the middle ware?
