It's a very cool thing and through the magic of virtiofs I'm (almost) at a point at which I have a script that I can point at a directory with a Linux file system and boot it in a microVM in under a second.
It required quite a bit of trial and error because the components aren't very well documented and don't seem to be made for each other. I meant to publish something about it but never got around to it.
It'll likely be a lot of work to get going, but it might contain some valuable hints that I had to search for through mailing lists and reading the QEMU source.
I remember needing a semi-custom kernel (maybe) and (I think) the rust version of virtiofsd.

This sounds interesting, would you be willing to share what you have so far?
I guess this is better than nothing: https://gist.github.com/solarkraft/c22b2742741a3dbc07a908266...
