I found out, this is caused by kubevirt tests. Kubevirt tests sets labels https://github.com/kubevirt/kubevirt/blob/3cc8a83016985e02b70dbebe987cb7b07faa6f9a/tests/vmi_lifecycle_test.go#L899 https://github.com/kubevirt/kubevirt/blob/3cc8a83016985e02b70dbebe987cb7b07faa6f9a/tests/vmi_lifecycle_test.go#L923 https://github.com/kubevirt/kubevirt/blob/3cc8a83016985e02b70dbebe987cb7b07faa6f9a/tests/vmi_lifecycle_test.go#L1009 https://github.com/kubevirt/kubevirt/blob/3cc8a83016985e02b70dbebe987cb7b07faa6f9a/tests/vmi_lifecycle_test.go#L1047 After the test is done, it doesn't do any clean up. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: Environment with bare-metal, RHEL7 workers. One worker (out of 3) has feature.node.kubernetes.io/cpu-feature-lahf_lm=true This should be set to false, as it is part of Penryn (which is set as minCPU in config map Version-Release number of selected component (if applicable): kubevirt-hyperconverged-operator.v2.2.0 How reproducible: Unknown Steps to Reproduce: - No specific steps to reproduce 1. Check min cpu value in configmap: # oc get cm kubevirt-cpu-plugin-configmap -n openshift-cnv -oyaml apiVersion: v1 data: cpu-plugin-configmap.yaml: |- obsoleteCPUs: - "486" - "pentium" - "pentium2" - "pentium3" - "pentiumpro" - "coreduo" - "n270" - "core2duo" - "Conroe" - "athlon" - "phenom" minCPU: "Penryn" 2. Create a VM and check min CPU xml ============================== # cat /usr/share/libvirt/cpu_map/x86_Penryn.xml <cpus> <model name='Penryn'> <signature family='6' model='23'/> <!-- 010670 --> <signature family='6' model='29'/> <!-- 0106d0 --> <vendor name='Intel'/> <feature name='apic'/> <feature name='clflush'/> <feature name='cmov'/> <feature name='cx16'/> <feature name='cx8'/> <feature name='de'/> <feature name='fpu'/> <feature name='fxsr'/> <feature name='lahf_lm'/> <feature name='lm'/> <feature name='mca'/> <feature name='mce'/> <feature name='mmx'/> <feature name='msr'/> <feature name='mtrr'/> <feature name='nx'/> <feature name='pae'/> <feature name='pat'/> <feature name='pge'/> <feature name='pni'/> <feature name='pse'/> <feature name='pse36'/> <feature name='sep'/> <feature name='sse'/> <feature name='sse2'/> <feature name='sse4.1'/> <feature name='ssse3'/> <feature name='syscall'/> <feature name='tsc'/> </model> </cpus> ===================================== 3. Check nodes CPU labels (see output below) Actual results: One node has feature.node.kubernetes.io/cpu-feature-lahf_lm=true This feature does not appear under node-labeller under annotations (node-labeller-feature.node.kubernetes.io) Expected results: cpu-feature-lahf_lm should be disabled / should not appear Additional info: See attached nodes yaml files
