This is a prototype for using the macOS Virtualization Framework to launch Linux VMs on macOS. See the README.md for details.
A bunch of new miscellaneous new features and improvements: - Rosetta is enabled on `aarch64-darwin`. This allows VMs to transparently run aarch64 and x86_64 Linux binaries simultaneously. - Install x86_64 binaries with Nix using the `--system` flag. For example, `nix profile install --system x86_64 <pkg>`. - The current Devbox project directory is now automatically detected and mounted. It can be found in `~/devbox` in the VM. - Devbox is automatically installed when the VM is created using the `github:jetpack-io/devbox?ref=gcurtis/flake` flake. - Starting a VM is now completely silent. The kernel's console is sent to `.devbox/vm/console` instead of stdout so that the first thing the user sees is their own shell prompt. - This work really well when launching a paused VM. If the VM resumes fast enough, it feels like using a normal shell. - Bootstrapping from an NixOS installer ISO with the `-install` flag is now fully automated. This is done by reading/writing to the VM's console using a pipe (similar to a program like `expect`). - Fixed a bug where stopping the VM would always return an error.
