Hi Gary, <div><br></div><div>Thanks for reporting this. <div><br></div><div>After some digging, the bug seems to have been introduced by an error in a blanket changeset to switch Nova from using json to jasonutils. During that translation, a "return" statement was dropped, meaning the serializer always returned Null regardless of what data was pushed in. See: <a href="https://github.com/openstack/nova/commit/ba76b954e69de56f76f9db5cade1780bc351be67#L5L42">https://github.com/openstack/nova/commit/ba76b954e69de56f76f9db5cade1780bc351be67#L5L42</a></div>
<div><br></div><div>Another bug where having Quantum be part of the gating process would have helped... so we really need to find resources to help get that work complete. </div><div><br></div><div>Patch here is trivial, so I'll push it and hopefully it can get reviewed quickly by the Nova core team.</div>

that this only happens to the default network created
when the installation is done via DevStack. For all
network created subsequently I am not seeing this
issue. I earlier thought that this might have
something to do with the exercises script getting
executed and possibly leaving a residue. However, in
spite of not running the exercises script I am still
seeing this issue. It seems that for some reason, the
initialize_gateway() was getting called only when a
new VM was being created. But here it seems to be
getting called before that (thus leading to the
creation of the bridge and the gateway devices), not
sure why. I am just trying to figure out how I can
test the fix with respect to the devstack setup (since
this happens only on installation)…</span></p>

<div><br>
</div>
<div>Your explanation makes sense. I think there was a recent
comment to automatically initialize all networks when
nova-network is started, in case nova-network was started on a
new host (e.g., in an HA configuration) or after a host
reboot. Since devstack creates the network using nova-manage
before starting nova-network, this would trigger the behavior
your describe. For more info, see: <a href="https://github.com/openstack/nova/commit/30c8293ea7d4c9464e0139fb488e202fd0947f52" target="_blank">https://github.com/openstack/nova/commit/30c8293ea7d4c9464e0139fb488e202fd0947f52</a></div>

probably not a devstack issue. The
problem is with the LB gateway

check for an existing bridge is
being performed, but the IP address
is being set outside that check.
Ideally, this code should not have
been invoked if the gateway was
already set. Something seems to have
changed in the QuantumManager as
result of which this code is being
invoked again. At any rate, I will
fix the LB gateway driver, and we

<pre>Hi,</pre>
<pre>This morning I encountered a problem (which did not happen a few days </pre>
<pre>ago :)). When devstack is launched, with quantum configured, the gateway </pre>
<pre>and bridge devices are created. This causes problems with quantum.</pre>
<pre> </pre>
<pre>For example when devstack is up and running prior to deploying an </pre>
<pre>instance we have:</pre>
