Nix app vms
Simple application VM's 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.
Designed primarily for full screen usage (but remote-viewer has ability to resize window dynamically without change resolution) without guest additions (because of less attack surface).
It's a proof-of-concept, but you can still use it. Also there is a lot of strange things inside, don't afraid of :)
Install Nix package manager
$ su -c 'mkdir -m 0755 /nix && chown user /nix'
$ curl https://nixos.org/nix/install | sh
Dependencies
$ su -c 'USE="spice virtfs" emerge qemu virt-manager'
Add appvm to PATH
$ echo 'PATH=$PATH:$HOME/appvm/bin' >> ~/.bashrc
(if you clone appvm to home directory)
Generate resolution
By default uses 3840x2160. If you need to regenerate appvm/nix/monitor.nix
:
$ appvm/appvm.sh generate-resolution 1920 1080 > appvm/nix/monitor.nix
Autodetection is a bash-spaghetti, so you need to check results. BTW it's just a X.org monitor section.
Create VM
$ $HOME/appvm/appvm.sh build chromium
You can customize local settings in nix/local.nix
.
Run application
$ appvm.chromium
Default hotkey to release cursor: ctrl+alt.
Shared directory
$ ls appvm/share/chromium
foo.tar.gz
bar.tar.gz
Close VM
$ pkill.... :)
App description
$ cat nix/chromium.nix
{pkgs, ...}:
{
imports = [
<nixpkgs/nixos/modules/virtualisation/qemu-vm.nix>
<nix/base.nix>
];
environment.systemPackages = [ pkgs.chromium ];
services.xserver.displayManager.sessionCommands = "while [ 1 ]; do ${pkgs.chromium}/bin/chromium; done &";
}
For create new app you should add package name (search at https://nixos.org/nixos/packages.html) and path to binary (typically same as package name).
