Virtualization Framework is awesome and I'm slowly building my own VirtualBox-like app, learning Cocoa programming. Hopefully will release it some day. One big thing that's missing is better storage support. Right now it's just disk image and that's about it. No way to implement something like qcow2 with snapshots and whatnot. It's missing a lot of opportunity for VMs. Another big thing that's missing is USB pass-through. Other than that: it does absolutely everything I need. It even provides some kind of hook for network which should allow to build userspace router with any network architecture (didn't try it myself, though, but I think it should work). I was able to implement thing that I missed for years on M1 mac. Basically I run Fedora VM, I installed Rosetta helper inside, and docker. And then automagically my x86 images started to work with reasonable speed. I don't know if Docker Desktop supports it already, I don't want to touch it with a longest stick in the world. But for myself I solved this issue. It was rock stable in my experience and just worked. qemu on the other hand managed to crash my entire macOS (hopefully that bug was fixed). Another thing that I liked about it: protocols are "modern" and open-source. Almost every driver is virtio. No ancient cruft. No proprietary things. Eventually other operating systems could be run on this solution.
