Hi,

you should also check your neutron auth configs and the respective log  
files since nova reports "Instance failed network setup after 1  
attempt(s)". Set nova and neutron to debug mode to get more output.  
You could also try to run different neutron commands with the same  
credentials and see if there occur any errors. Breaking it down to a  
specific service will help identifying the issue.

Regards
