is there any way to change hostname by changing instance name. I tried changing instance name and then did a hard reboot but hostname is still the same.If this is not the right approach for changing hostname can some one tell me what should be done to change hostname of instances without logging to instance. tried on Juno-Neutron and icehouse-nova-network none worked Thanks for any help -------------- next part -------------- An HTML attachment was scrubbed...
