I am a novice on openstack. I have followed the steps to intell openstack on my Intel based linux box (not on a virtual machine): http://ubuntu-cloud-installer.readthe...

With "sudo openstack-install --upstream-ppa" after 2 hours, I found all services are up and running, then I was able to login to horizon.

But after reboot the linux and the linux box, I cannot access to horizon any more. Actually, I do not know the proper procedure how to reboot the machine, I just reboot the linux system.

I believe there should a way to shutdown openstack and rejoin the stacks after reboot, which I don't know how. When I checked the "openstack-status", it looks pretty normal and all services are running right after reboot. But I don't really sure they are really running.

If I understand you right, it seems like you have disabled Unity. I did the same in Ubuntu 15.04.

If you can see your mouse, right-click to access the terminal, otherwise hit Ctrl+Alt+t. From there, enter the following in terminal:

dconf reset -f /org/compiz/

then

setsid unity

I found this answer here. Hope it helps.

P.S. To reboot, type sudo reboot or sudo shutdown -r now.

  • Sorry, it not about the rebooting linux OS, it is related how to restart openstack running on the linux. Thanks anyway. – notilas Oct 16 '15 at 16:50
