Vagrant is an orthogonal tool to this, it is a VM orchestrator not an actual VM. What does this do: well, qemu doesn't have virgl support merged yet, so you need to go to some lengths to compile it for yourself.
All of the other stuff (spice, virtio) is for "it should be a nice user experience and perform well" above and beyond simply being fast enough to use. In other words, you should be able to copy and paste between the host OS and the guest. You should be able to slide your mouse across the border of the VM window and do some clicking around then simply slide it back out and use your mouse with native host-OS windows again. It should have all of the features you expect and not force you to read a bunch of tutorials to find the features you expect from your desktop VM.
These things are all not granted when you use qemu out of the box. I have this intense 25-lines "qemu" script for invoking qemu-system properly. It was enlightening but I'm not sure how much I was enriched by the process of actually figuring all this out.
Quickemu is, I guess, for making figuring out all this stuff and making it easier to do (and on Linux.)

Do you have your script posted publicly somewhere?
This expects you're using the special qemu from the prior link, compiled with homebrew. (else I think there will be no virtio-vga-gl video driver?)
The guest OS is an Ubuntu VM. I think the instructions say to use a recent Fedora/Silverblue for a reason (there are some things that don't quite work right around window resizing.)
Each time I start the VM, it shows up with tiny tiny pixels and the menubar does not work. I switch to another app, switch back, go to the menu and enable "zoom to fit" and it's off to the races. Other things to be aware of, if you resize the window it actually scales the pixels, (which is OK and doesn't even have any noticeable perf impact because OpenGL, I guess)
