I am using Openstack Icehouse running on Ubuntu.
After rebooting Compute node all instances that were running there will be in shutoff state. Is there way to restart them all at once?
Only thing I found from the documentation was starting them individually with
nova start instance_id
which is really impractical if I have large number of instances.
Web interface Dashboard is no better. I would still have to click each instances individually to get them started.
What would be the best way to handle this?
