<p>Hi All,</p>
<p>I was wondering if anyone could point me in the right direction
with an issue we are having adding in new compute nodes to our
platform. We have been trying to add a few new compute nodes to
increase our capacity and upon configuring them with OSA and them
appearing to be in service we have noticed that no new instances
are provisioning onto them. We did a test by disabling all compute
nodes except for the new ones and an instance launch failed with
"No valid compute hosts were found"</p>
<p>We have enabled debug mode on Nova and also looked at the
nova-api containers ( scheduler, compute etc ) and it appears
there is not even an attempt to try and launch an instance on the
new hosts from what we can see.</p>
<p>The only thing we have noticed on the newly added hosts is that
the "privsep-helper" doesn't appear to be started whereas on a
working node it is running.</p>
<p>We have not changed the software versions of OpenStack or OSA, we
are running Queens.</p>
<p>The newly added compute node is reporting itself back fine from
what we can see:</p>
<p> Total usable vcpus: 72, total allocated vcpus: 0

<p>Does anyone know of any other logs we can check / enable that
might lead us in the right direction to figure out why the new
hosts are not adding in?</p>
<p>Any help would be greatly appreciated as we are a bit stumped at
the moment.</p>
<p>Many thanks,<br>
