Managing port level security in OpenStack

I am investigating why dpdk doesn’t work inside an instance.

 

The OpenStack platform, specifically Neutron (the networking component), uses the concepts of “ports” in order to connect the various cloud instances to different networks and the corresponding virtual networking devices like Neutron routers, firewalls etc.

The default security on these ports is quite restrictive (and rightly so) since the platform is supposed to be an autonomous, mostly independent system hosting multiple cloud tenants (customers) or different cloud instances with varying security requirements. To get a better feel on ports, take a look at the diagram below.
