Personally, I wouldn't recommend trying to virtualize macOS on an Apple Silicon Mac with less than 16GB of RAM.

But you'll be running two entirely separate OSes on the same computer, and that comes with RAM and storage requirements. VirtualBuddy and the Virtualization framework don't have hard-and-fast requirements aside from requiring an Apple Silicon chip for macOS-on-macOS virtualization.

You'll also want to pay attention to the hardware requirements for virtualization. With the Xcode beta installed, everything works as intended (but if you can find a way to get this working without installing a 33GB app that takes an hour-plus to install, I'd love to know about it). When I've tried this without Xcode installed, macOS has tried (and failed) to download extra software to make it work-sort of like how macOS needs to download additional software the first time you use Rosetta. If you're looking to virtualize Ventura on top of Monterey, you'll want to install and run the beta version of Xcode 14 from Apple's developer site before you start. If you want to virtualize macOS Monterey on top of macOS Monterey, you won't have to download anything else.
