Hi Eric,

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.

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.

Regards,
