Hi everyone,

I'm working on a single node installation of openstack(for testing). I'm
using ubuntu uec images and am successfully able to boot them. But
unfortunately, I get the error

DataSourceEc2.py[WARNING]:   20:07:30 [17/100]: url error [[Errno 101]
Network is unreachable]

at the end of "euca-get-console-output". I believe that is the reason why
I'm not able to either ping or ssh into the instance.

There already exists a pre-routing rule to redirect all the communication
from 169.254.169.254:80 to nova-api:8773.

-A nova-network-PREROUTING -d 169.254.169.254/32 -p tcp -m tcp --dport 80 -j
DNAT --to-destination 10.2.4.135:8773

Any suggestions?

Regards,
Shashank Sahni
