I have deployed Openstack queens for testing purposes.
nova --version
14.2.0
I noticed that when I reboot a compute host, all VMs running on it turn into SHUTOFF state.
I tried to change this behaviour by editing flavor metadata. I have added CIM_VSSD_AutomaticStartupAction property and have set it to the "Always startup" value, but no changes occur.
Is there any way to autostart a VM when compute node starts up?
