Comment 5 for bug 1796812

I think I see where the confusion is happening. In R3.1, the version of OpenStack Nova provided by Juniper was hacked to not require the PCI allocation. This change was not acceptable for upstream OpenStack and had NUMA issues. The current VNIC based method is acceptable upstream (openvswitch, mech_sriov and others are using this mechanism), works with NUMA and is available since OpenStack Pike.

A side effect of this is that accelerated ports have to be plugged using port-based attachment. The net-based attachment is a convenience function: behind the scenes a port is still created.
