A hosted runner of the ubuntu-24.04 pool is not promised nested virtualization, and 3 of the 16 suites of run 42182554717 failed the check of /dev/kvm. rerun-no-kvm.yaml could not help: a workflow_run workflow runs only from the default branch, where the file is not, and a run cannot rerun its own failed jobs while it is in progress. The step "Enable KVM" of the nix action is now the only one that enables KVM (enable_kvm of install-nix-action is off), runs before the disk and the install, waits for udev to settle and polls /dev/kvm for 30 seconds instead of testing it once, 42 ms after an asynchronous udevadm trigger, and prints what tells a missing device from a rule that was not applied yet. With defer-no-kvm a host without KVM is an output, not a failure. _vm.yaml calls _vm-attempt.yaml up to three times: the suites that found no KVM are listed through the artifacts of the run and run again on new machines, and the last attempt fails them. vm-fast and vm-slow are calls of it. rerun-no-kvm.yaml is removed.

# The KDE VM suites of a tier, with the draw of the host repeated for the ones that found no KVM.

#
|
|
# GitHub documents hardware acceleration on its Linux runners, and does not promise it of every host of
|
|
# the pool (docs/dev/ci.md, "KVM"). A suite whose machine has no /dev/kvm is run again on a new machine,
|
|
# in the attempt after, up to three in all. Everything is in this one run, so that it works on any
|
|
# branch and any event, and the check that a ruleset requires is the result of this workflow call: green
|
|
# when every suite ran and passed, red when a suite failed, or when no machine had KVM in three draws.
|
|
#
|
|
# The caller grants `actions: read`, which the planning of the later attempts needs.
