Open Stack

Hi,
I have an Openstack environment (Icehouse) installed on a Debian server, 
which is a unique server with all services (nova, keystone, glance, 
neutron..). The hypervisor is KVM.

I'd like to have VM booted up automatically , when server i rebooted ,
Is there a parameter to gain this behaviour ?

Thanks and regards
