`colima start --vm-type=vz` failing when installed from Nix

[jonathanlking]

Description

Running colima start --vm-type=vz fails to start:

$ colima start --vm-type=vz --very-verbose

However colima start works as expected.
When installed through Homebrew it works (see additional context).

Version

Colima Version:

colima version 0.5.2
git commit: 6b5b6fe

Lima Version: limactl version 0.13.0
Qemu Version: qemu-img version 7.2.0

Nixpkgs: https://github.com/NixOS/nixpkgs/blob/2d1dee4f6a6dac81b3bc4a3e7bdf76c9e5ec4008/pkgs/applications/virtualization/colima/default.nix

Operating System

• macOS Intel <= 12 (Monterrey)

Output of colima status

FATA[0000] colima is not running

Reproduction Steps

1. nix-shell -p colima -p qemu -p lima -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/2d1dee4f6a6dac81b3bc4a3e7bdf76c9e5ec4008.tar.gz
2. colima delete (only if you've already run colima before with different settings)
3. colima start --vm-type=vz

Expected behaviour

VM should start.

Ah, I think the problem might be that Nixpkgs has limactl version 0.13.0 when >= 0.14 is required for vz.

Apologies I only spotted this right after creating the issue! 🤦

This release adds an experimental support for Apple's Virtualization.framework aka vz.

https://github.com/lima-vm/lima/releases/tag/v0.14.0

@jonathanlking I'm not very skilled with Nix, otherwise would've modified Colima to only use a specific version of Lima.

The issue with Nix is due to the fixed dependencies. I think a new re-release on Nix should resolve it as newer versions of Lima is now on Nix.

[jonathanlking]

Thanks for such a quick reply!

Unfortunately I think master https://github.com/NixOS/nixpkgs/blob/master/pkgs/applications/virtualization/lima/default.nix is still on 0.13.0.

I'm creating an overlay now to test if upgrading to 0.14.2 fixes this issue (which I'm hoping/expecting it will!).

I'll add the overlay below (in case anyone else runs into this issue) and will try to open a PR on nixpkgs to bump the version there too.

[jonathanlking]

It looks like this issue is being discussed/worked on already 👀 (and I haven't got any further than them)

• colima: 0.5.0 -> 0.5.2 NixOS/nixpkgs#208094
• lima: 0.13.0 -> 0.14.2 NixOS/nixpkgs#206285

I'm happy for this issue to be closed, as it appears to be a Nix packaging issue, rather than anything wrong with colima.
Equally happy happy for it to be left open as a signpost to others.

I still have the same behavior with up-to-date colima and lima.

colima start --vm-type=vz

OSX: 13.1 (M1 max)
colima version 0.5.2
limactl version 0.14.2

edit:
The error message is different now

Terminal is not available, proceeding without opening an editor

Same here. What's strange is that the YAML file mentioned in the comment (main file) doesn't exist.

Hi there, I recently worked on these nix packages to make them up to date.
Colima is up to date, but it is a bit more complex with Lima.
Due to the nature on how packages are build in nix, lima is built in a sandbox that doesn't contains all the recent macos libraries, including vz support. Another contributor added a lima-bin package that pulls the github hosted pre-compiled binaries for lima that are compiled with vz support.
In order to use them you need to override the lima package used by colima. in my home-manager config it looks a little bit like this.

{
  nixpkgs.overlays = [
    (self: super: {
      lima = super.lima-bin;
    })
  ];

  home.packages = with pkgs; [
    ...
    colima
    ...
  ];
  ...
}

Once updated macos toolchain will be updated with vz support, this overlay will not be necessary anymore, but I can't tell when this will be done.

This is fixed in nixpkgs-unstable with NixOS/nixpkgs#212980
