Simple application VMs (hypervisor-based sandbox) based on Nix package manager.

Uses one read-only /nix directory for all appvms. So creating a new appvm (but not first) is just about one minute.

The home directory of each appvm is inside ~/appvm, so you can easily share files between the two as and when needed

1. Clone this repo.

2. Run go build to build the program

3. Run ./appvm generate brave to generate the config files for Brave.

Note: If you use flakes for NixOS, nix channels probably won't appear when you run this as a normal user. Run the command as root in this case (it just needs to create configs, it doesn't do anything else)

4. Run ./appvm start brave to launch Brave inside the VM. (this can be done as your user only, you don't need to use root!)

Right now as a proof of concept only Brave is contained inside the config, however the code can be extended to allow any program you want here.

You can customize local settings in ~/.config/appvm/nix/local.nix.

Default hotkey to release cursor: ctrl+alt.

$ ls appvm/chromium
foo.tar.gz
bar.tar.gz

$ appvm stop chromium
