<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">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>
