<p>Hi Cory,</p>
<p>Thanks for the response. I'll take a look at the metadata service
from the instance and from OpenStack itself tomorrow now. It's
midnight here in the UK and I need to get some rest. Thanks for
the tip, hopefully I'll find something useful to go on from there.</p>

<p>Hi Eric,<o:p></o:p></p>
<p>Thanks for getting back to me. I am fairly sure it is a DHCP
error. The instances are getting an IP when they eventually
boot, it is just taking a long time for them to bring up
networking. The strange thing is, it only seems to be new
tenants. All existing tenants are absolutely fine. <o:p></o:p></p>
<p>I can check DNS as well just to be on the safe side, however
I wasn't seeing any errors in the Nova or Neutron logs when
the instance(s) were being created.<o:p></o:p></p>
<p>Regards,<o:p></o:p></p>

<p>Hi all,<o:p></o:p></p>
<p>I wonder if anyone can help shed any light on an odd
issue we are seeing with only a couple of specific
tenants. Basically if they launch an instance they are
taking about 5 minutes to launch rather than our usual 30
second or so launch.<o:p></o:p></p>
<p>We are seeing the following on the instance logs:<o:p></o:p></p>
<p><a href="https://pastebin.com/hDstsd8G"
moz-do-not-send="true">https://pastebin.com/hDstsd8G</a><o:p></o:p></p>
<p>Weirdly it only seems to be happening for 1 or 2 new
tenants. I have tested this on our personal account and a
few other customers have tested and their instances launch
really quickly as expected.
<o:p></o:p></p>
<p>Is there anything specific during the tenant creation
that can cause this issue? Or are there any logs in nova /
neutron I should be looking out for that might shed some
light?
<o:p></o:p></p>
<p>I haven't seen anything that is obvious. Any help would
be much appreciated as we are a little stumped at the
moment.<o:p></o:p></p>
<p>Many thanks,<o:p></o:p></p>
