I decided to try the minimal template way.
I already created templates and app-VM for sys-net and sys-firewall. everything works great out of the box.
Now I created a template fedora-33-minimal, installed chromium there, close template, then create app-VM based on the template e start cromium there.
BUT… now this appVM has no internet.
(First I thought it was a problem with sys-net or sys-firewal, but other app-VM (based on fedora-32) all have internet connection.
Has anyone some explanation / solution to this?
Am I doing something wrong here?
(Yes, I am sure I have rtfm
