I have created one OS template...and now when i use this template to create the VM...the cloud-init network doesn't set in the VM....and from the VM console i can see the following error :- 

url_helper.py [WARNING] Calling 'http://169.254.169.254/2009-04-04/meta-data/instance-id' failed: url error [[Errno 101] Network unreachable]

Thanks,

Punit
