I think all you need to do is to enable the libvirt-guests service.  It is part of the libvirt-client package so you should have it installed.

systemctl enable libvirt-guests

I do NOT use that feature.  I manually shutdown guests.  That service basically suspends the VMs to disk... and if I have a VM with 32GB of RAM, it has to write a 32GB dump file.  If you have a few of those, it can take longer to suspend and restore than simply shutting down the host and starting it again.

On guests with small/reasonable amounts of RAM, it probably is nice to have turned on.
