[Openstack-operators] Auto start running Nova Instances after reboot

I’m looking for a way to ensure running instances are started on a host after 
reboot, I’ve seen a way to do this for RHEL and CentOs by using 
/etc/sysconfig/libvirt-guests but it is not available on Ubuntu as far as I 
know.

Hello,

On your compute nodes in nova.conf

[DEFAULT]

resume_guests_state_on_host_boot = True


All instances that had a running state when the reboot occured will be started 
again.

Best regards

And this works regardless of the operating system, we use it on Ubuntu.
