Description RHOS Integration 2013-12-12 16:01:22 UTC

Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/selective-guest-autostart.

Description:

This blueprint introduces selective guest autostart into OpenStack.
Today, there is a configuration option named “resume_guests_state_on_host_boot” in nova.conf. The option determines whether to
start VMs that were running before the host rebooted. This only works when required services, like
AMQP and database are up and running.

This blueprint allows OpenStack
administrator to select an individual guest and make it automatically start in case its host is rebooted,
regardless of other OpenStack services are up or not. 

The benefit that are brought by this feature is to make it possible to deploy OpenStack services on a VM and have that VM automatically restarted. This is useful if a cloud system is expected to be brought back quickly after failures like power loss in the entire data center.
