The podman statically compiled and QEMU

[PedroRegisPOAR]

podman machine

The status is: https://blog.replit.com/nix-vs-docker

Fact: since https://github.com/containers/podman/releases/tag/v4.3.1 exists the static version.

is there documentation on the ignition file itself? I saw the cli arg to pass it in but I can't find any documentation on the actual content of that file.

no there is not ... we dont envision people messing with an individual ignition file. But we added support for providing one. https://github.com/containers/podman/issues/13900#issuecomment-1108830848

This file must be created or update after each podman machine init:

less ~/.config/containers/podman/machine/qemu/$(podman machine info --format "{{ .Host.CurrentMachine }}").json

What it means?

I haven't found a solution yet, but if qemu is not using Apple virtualization, then he should be able to run. https://github.com/containers/podman/issues/12617#issuecomment-1003504346

Is this about tcg?

And this workaround? https://podman-desktop.io/docs/troubleshooting/troubleshooting-podman-on-macos#podman-machine-on-apple-silicon

The fix. Edit it to have this:

Start the podman machine VM:

echo First start the podman virtual machine \
&& podman --log-level=trace machine start vm \
&& echo The machine must have started \
&& podman --remote --log-level=ERROR run quay.io/podman/hello 

Note: it takes around 8min to finish, maybe more.

ehh... broken, of course... TODO: maybe the problem is the nested virtualization? On metal it would it work?

Tip, maybe -accel tcg

Updating qemu and trying again

nix profile install github:NixOS/nixpkgs/f3dab3509afca932f3f4fd0908957709bb1c1f57#podman github:NixOS/nixpkgs/f3dab3509afca932f3f4fd0908957709bb1c1f57#qemu github:NixOS/nixpkgs/f3dab3509afca932f3f4fd0908957709bb1c1f57#jq 

Still broken

nix run github:NixOS/nixpkgs/nixpkgs-unstable#darwin.builder

error: 'darwin.builder' has been changed and renamed to 'darwin.linux-builder'. The default ssh port is now 31022. Please update your configuration or override the port back to 22. See https://nixos.org/manual/nixpkgs/unstable/#sec-darwin-builder

Broken

Colima

Now trying colima...

nix profile install github:abiosoft/colima/f2c91a1b5bd4d0764ac3c4d889ad5d4d9837f639

Of course it is broken, it the default... what would be the fun right?!
