Is there a way to either install jellyfin inside of retropie (lol), or somehow have a UI that lets the user switch between retropie and jellyfin?

This makes no sense. I have some reolinks and a Ubiquiti Dream Machine router. I am trying to block the internet on to make them only accessible via local network and VPN. I go to uniquiti / settings / application firewall / traffic rules, and there I choose "block", then "internet" in "category", and select my cameras. This makes them inaccessible from the internet, but accessible via local network. Great. But then, if I connect to my cellphone's internet and turn on the wiregaurd VPN connection to my UDM, the connection works (I can use internet), but the cameras are not accessible. What is going on?

I have a sweet ubuntu install with my services on it, and also have a MacOS install (dual-boot). I want to move my Ununtu install into a VM inside MacOS so I dont have to switch between them. How? I assume something like “create an image of your install” and “install it in a VM”, but specifically how?
