The physical hosts no longer need k3s or KubeVirt: aquamarine runs natively, the k3s-test masters run as microVMs and kana/ruby under libvirt. So drop the host cluster and split the shared parts out of the KubeVirt host module: - lib/genVmHostModule.nix: the host bits the VMs still need (br0 + the physical NIC as a bridge port, KVM, sysctls, earlyoom, libvirt, journald, stateVersion) - the three hosts use it and drop genK3sServerModule; also drop the longhorn workarounds (openiscsi + the /usr/local/bin tmpfile) and the virtctl package - remove lib/genKubeVirtHostModule.nix
