Yes, that is correct. Keep in mind though that you will need to
Stop/Start the VMs or (Live) Migrate them to a different hypervisor for
the new packages to be loaded.
Actually the hosts are Fedora 29 which I need to re-deploy with Fedora 30 to get nautilus on the clients.
I just wanted to unterstand how this works. I always reboot the whole machine after such a large change to make sure it works.
Thank you for your time!
