I installed devstack on ubuntu 16.04 running on virtual box. The first time everything came up and i was able to access all services. I turned off my VM and reopened it again and now the keystone service is not starting.
I have been reading lot of forums which say devstack installation is corrupted and i have to run stack.sh again. But isn't there any way to bring up the existing keystone service ? All the other services running.
I have tried "sudo systemctl start devstack@keystone.service" but it doesn't work.
Please provide a solution for this. Thanks!
