From f8ce01525434e8e2ffc0347896aa3c6ee3dfae39 Mon Sep 17 00:00:00 2001 From: Colin Walters Date: Tue, 4 Nov 2025 09:20:56 -0500 Subject: [PATCH] Rework GHA testing: Use bcvk, cover composefs with tmt Part 1: Use bcvk For local tests, right now testcloud+tmt doesn't support UEFI, see https://github.com/teemtee/tmt/issues/4203 This is a blocker for us doing more testing with UKIs. In this patch we switch to provisioning VMs with bcvk, which fixes this - but beyond that a really compelling thing about this is that bcvk is *also* designed to be ergonomic and efficient beyond just being a test runner, with things like virtiofs mounting of host container storage, etc. In other words, bcvk is the preferred way to run local virt with bootc, and this makes our TMT tests use it. Now a major downside of this though is we're effectively implementing a new "provisioner" for tmt (bypassing the existing `virtual`). In the more medium term I think we want to add `bcvk` as a provisioner option to tmt. Anyways for now, this works by discovers test plans via `tmt plan ls`, spawning a separate VM per test, and then using uses tmt's connect provisioner to run tests targeting these externally provisioned systems. Part 2: Rework the Justfile and Dockerfile This adds `base` and `variant` arguments which are propagated through the system, and we have a new `variant` for sealed composefs. The readonly tests now pass with composefs. Drop the continuous repo tests...as while we could keep that it's actually a whole *other* entry in this matrix.
