argunix pre-flight: no connected builder satisfies this derivation's
requiredSystemFeatures. Failing fast instead of waiting for nix's
remote-build scheduler to give up.

attribute: checks.x86_64-linux.zot-image
derivation: /nix/store/rm61sjrcyaszkz97kp5645i7icsxfy73-vm-test-run-zot-image.drv
required (system, features): (x86_64-linux, ["kvm", "nixos-test"])

connected builders:
  - argunixdev: systems=["x86_64-linux", "aarch64-linux", "i686-linux"] features=["benchmark", "big-parallel", "nixos-test"] max_jobs=2 state=Active

Fix one of:
  1. Add the missing feature(s) to a builder's nix.settings.system-features.
  2. Add a builder host that natively satisfies the feature.
  3. Drop the requirement from the derivation if it isn't actually needed.
