I made a new topic because it was off topic and or an old one.
About your question how to start with virt-manager is quite simple:
sudo dnf group install virtualization
Open the virt-manager and try to create a new virtual environment.
Our doc about virtualization needs review. So you might have a look for other tutorials/manuals.
The below looks quite new. As it is written for Debian you can continue by step 4 as the installation is done with the command above.
