Is there a way to have Nix run a VM or something else to run things like tests when cross compiling?

Let me know if there's a better place to ask (#Nix on macOS maybe?), but would bit be possible to also have a x86_64-linux VM using this?

This is a project I was working on to create a generic debug VM to run a node for my team to test. It works on MacOS, opens up a Linux qemu instance.

Is there a non-zero chance of being able to build a python app using pkgsCross.mingwW64? I'm running into issues early on with bash complaining it can't run as a pe executable (seems totally reasonable, but I'm not sure where it's decided it needs to do that)

Or alternatively, any chance of being able to build python things for windows in some form of VM/wine/something

I'm sorry, I'm not quite sure what you mean. I currently have a file that is like

{ pkgs, stdenv, rustPlatform, ...}: stdenv.mkDerivation {
depsBuildBuild = [rustPlatform.rust.rustc rustPlatform.rust.cargo];
...other stuff
}

Which is called from another file with a rust-overlay toolchain using makeRustPlatform. I am wondering if I can change it to

{ pkgs, stdenv, rustPlatform, rust, cargo, ...}: stdenv.mkDerivation {
depsBuildBuild = [rust, cargo];
...other stuff
}

as it keeps yelling at me that using rustPlatform.rust.{rustc, cargo} is deprecated.
