I created a debian image which is of QCOW2 type and launched a instance using the same image. instance was successfully running and image creation was succesful too. I want to persist this and all other changes i will make into devstack even after host reboot.
I tried running: screen -c stack-screenrc
but running that script shows the following results.... enter image description here
I referred following link
https://ask.openstack.org/en/question/5423/rebooting-with-devstack/
but rejoin-stack.sh script doesn't exists in my devstack. any alternative suggestions?
