I am trying to run Devstack, my local.conf looks like this


When I run ./ everything works as expected. I am able to access horizon, create instances, etc. Before shutting down the machine I run ./ When I later start the machine again I start devstack by using screen -c stack-screenrc. I am able to access horion, however when I try to log in I get an invalid credentials error. I looken in horizon screen and I saw the following errors

2017-02-18 16:51:18.687058 DEBUG:keystoneauth.identity.v3.base:Making authentication request to
2017-02-18 16:51:18.725239 DEBUG:keystoneauth.session:Request returned failure status: 404
2017-02-18 16:51:18.725569 Login failed for user "demo", remote address

If I run ./ again everything works until reboot/shutdown. Am I doing somehting wrong wrong when starting devstack after reboot? I don't wan't to run ./ evrytime since it takes a long time to complete and I don't want to wipe my data.

Devstack is not made for rebooting.

Packstack may be an alternative. It's as simple to set up as Devstack (or simpler), and it survives reboots, but you are limited to RHEL or a derivative as the underlying OS.

Running your Devstack on a VM that you save and restore rather than reboot is another option.

Probably you saw 'devstack after reboot of host' in Google and note that was removed. Hmm, 'screen -c stack-screenrc' was an option before...

Maybe having a snapshot of VM and restoring from snapshot after reboot/shutdown is an option?
