Yeah I had noticed that change too… I’m guessing that, if I want to try to use the Nova call, that I’d want to set both the hybrid plug and port filter flags to false?
<div><br>
</div>
<div>For my devstack setup, I have Neutron security groups disabled (Q_USE_SECGROUP=False), and I setup Nova to allow ICMP and SSH.</div>

Hi,<o:p></o:p></div>

<div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;">
I have a VM that I start up outside of OpenStack (as a short term solution, until we get it working inside a Nova VM), using KVM. It has scrips associated with the three interfaces that are created, to hook this VM into Neutron. One I/F is on br-ex (connected
to the “public" network for DevStack), another to br-int (connected to a management network that is created), and a third is connected to br-int (connected to the “private” network for DevStack). It’s understood these are hacks to get things going and can
be brittle. With DevStack, I have a vanilla localrc, so using ML2, without any ML2 settings specified.<o:p></o:p></div>
</div>
<div>
<div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;">
<o:p> </o:p></div>
</div>
<div>
<div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;">
Now, the first two scripts use internal Neutron client calls to create the port, and then plug the VIF. The third, uses Neutron to create the port, and then Nova to plug the VIF. I don’t know why - I inherited the scripts.<o:p></o:p></div>
</div>
<div>
<div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;">
<o:p> </o:p></div>
</div>
<div>
<div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;">
On one system, where Nova is based on commit b3e2e05 (10 days ago), this all works just peachy. Interfaces are hooked in and I can ping to my hearts content. On another system, that I just reimaged today, using the latest and greatest OpenStack projects, the
third script fails.<o:p></o:p></div>
</div>
<div>
<div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;">

</div>
<div>
<div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;">
I talked to Nova folks, and the vic is now an object, instead of a plain dict, and therefore calls on the object fail (as the script just provides a dict). I started trying to convert the vif to an object, but in discussing with a co-worker, we thought that
we could too use Neutron calls for all of the setup of this third interface.<o:p></o:p></div>

<div style="margin: 0in 0in 0.0001pt; font-size: 12pt; font-family: 'Times New Roman', serif;">
Well, I tried, and the port is created, but unlike the other system, the port is DOWN, and I cannot ping to or from it (the other ports still work fine, with this newer OpenStack repo). One difference is that the port is showing {"port_filter": true, "ovs_hybrid_plug":
true} for binding:vif_details, in the neutron port-show output. On the older system this is empty (so must be new changes in Neutron?)<o:p></o:p></div>
