to the live migration pre-checks on source node, but we never moved piece of code that populates this data while executing pre-checks on destination node.<o:p></o:p></span></p>

<p class="MsoNormal">Hi,<o:p></o:p></p>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">In Kolla, we are having an issue with Nova's VNC / SPICE address and live migration. Currently, we are declaring the IP address for vncserver_listen on each node (via ansible). However, when a live migration is performed, it fails due
to this address not being available.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">The hack is to switch the vncserver_listen to be 0.0.0.0, but this is horribly insecure and breaks the network isolation that kolla supports.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Looking at the relevant code, this looks like it should be functional via VIR_DOMAIN_XML_MIGRATABLE, but it doesn't seem to be working.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">Could someone from Nova help us determine the cause? We are tracking this as bug 1596724<o:p></o:p></p>
