There was a problem hiding this comment.
I do something pretty advanced here so don't worry about understanding every line, but essentially I'm extending nixpkgs with an overlay to add nix-snapshotter. I'm touching _module.args.pkgs here which influences the function arg pkgs that NixOS modules have access to.
TLDR; the NixOS module's pkgs now has pkgs.nix-snapshotter.

This lets you run a VM with just
nix run .#vm! Uses the upstream containerd module + nix-snapshotter service from @rbpdt's branch infeature/nix-vm. Verified that it works.Still has a failure with
nix flake check, I assume it's not happy with the VM not having a grub device and rootfs but I'm able to run a VM just fine without it.TODO
