Openstack: How to make a VM to autostart

Question

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?

Which VM? Presumably they should all be already running on the other compute nodes. — Michael Hampton, Sep 06 '19 at 07:21
@MichaelHampton VM that's running on that particulat compute node. I think a VM will not run on 2nd node after 1st node fail because there are a lot of complex conditions for it. First of all a common storage system is needed. This is what I want but for older openstack version: https://www.linuxtopic.com/2017/09/instance-autostart.html — Anton M., Sep 09 '19 at 04:21

Edit vi /etc/nova/nova.conf and set this to true

resume_guests_state_on_host_boot=true

then restart nova service

systemctl restart openstack-nova-compute

Note that the setting needs to be set on the compute nodes, not on the control nodes. – Gerald Schneider Feb 24 '20 at 07:10
