non-NixOS
GL-related error

https://nixos.org/manual/nixpkgs/unstable/#nix-on-gnulinux

If you are using a non-NixOS GNU/Linux/X11 desktop with free software video drivers, consider launching OpenGL-dependent programs from Nixpkgs with Nixpkgs versions of libglvnd and mesa.drivers in LD_LIBRARY_PATH.

Check if https://github.com/guibou/nixGL works around it for you.

nix run --override-input nixpkgs nixpkgs/nixos-21.11 --impure github:guibou/nixGL -- quickemu --vm alpine-latest.conf works.

Thank you very much for the assistance.

I assume this is the expected behaviour and so I'm closing this issue.

[OPNA2608]

It's sadly a known problem, see #9415 for the relevant issue.

Adding --display spice worked for me.
quickemu --vm macos-catalina.conf --display spice
