kvm - Can OpenStack be configured to start certain instances when the hypervisor reboots? -

say have powerfulness outage, , hypervisor gets reset. openstack start nova services, etc.

but, not start vms running when hypervisor went down. can configured this?

perhaps 1 workaround create startup script on hypervisor, or crontask somewhere, starts specified vms assigned hypervisor if not running, that's less ideal..

currently running havana kvm, upgrading icehouse soon.

there's section in /etc/nova/nova.conf:

# whether start guests running before host # rebooted (boolean value) #resume_guests_state_on_host_boot=false

if uncomment lastly line, , alter =true, restart nova services everywhere, should want.
