The k3s-test workers never ran (they were stuck waiting for volume
binding) and will be re-added as microVMs, so remove their KubeVirt
configs and everything that only existed for KubeVirt guests:
- hosts/k8s/k3s-test-1-worker-{1,2,3} and their outputs
- lib/genKubeVirtGuestModule.nix and lib/genK3sAgentModule.nix (the
latter was only used by the workers)
- the KubeVirt image upload recipes (upload-vm, upload-idols,
upload-k3s-test) and the kubevirt image package in the idols outputs
- refresh the docs; keep only accurate historical mentions (e.g. the
restic backup path must stay as it is)
The VMs now declare their root disk as a DataVolume with `source: upload`, so
upload straight into `<vm>-disk` (CDI only accepts an upload into a DataVolume)
instead of a shared golden PVC. Takes the disk size as an argument.
* feat(kubevirt-youko): export a shared golden-image store over NFS
* feat(vm-images): upload golden images into the cluster
Replace the rsync-to-orangepi5 step with a CDI upload into the golden-image
PVCs (vms/golden-images in k8s-gitops), so VM images no longer depend on the
single-board file server.
