Hi Grant, Are you sure this is a DHCP timeout and not a DNS resolution issue? I ask because we have seen a strange DNS issue occur that can cause something similar. Are the VMs being assigned an IP after they finally boot? Eric K.

Basically if they launch an instance they are taking about 5 minutes to launch rather than our usual 30 second or so launch. We are seeing the following on the instance logs: https://pastebin.com/hDstsd8G 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. 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? I haven't seen anything that is obvious. Any help would be much appreciated as we are a little stumped at the moment.
