…irt 6.1) OpenSCAP node rule checking that nested virtualization is disabled: the 'nested' parameter of kvm_intel/kvm_amd (exposed at /sys/module/kvm_*/parameters/nested) must be N or 0. Nodes where the KVM modules are not loaded do not expose the parameter, which is compliant - so the rule is inert on non-virtualization nodes without needing a CPE. Custom OVAL: for each module, absent-file (none_exist) OR content ^(N|0)$. Validated on real hardware: a host with kvm_amd nested=1 evaluates false (non-compliant) and the absent kvm_intel branch evaluates true, via oscap oval eval of the built ssg-ocp4-oval.xml.

…controls) Node companion profile for the CEL-based cis-vm-extension platform profile, hosting the benchmark's node-level controls. 'platform: ocp4-node' maps to the openshift_container_platform_node CPE, from which the Compliance Operator derives Node-type scans (per-role master/worker), same as cis-node. The content build rejects profiles with no selections, so the profile ships with its first rule, kubevirt-nested-virtualization-disabled (CIS 6.1, CMP-4443). The remaining node rules add their selections under their own tickets: CMP-4441 (1.8 seccomp profile permissions), CMP-4442 (1.9 cache directory permissions), CMP-4444 (6.2 vCPU metrics), CMP-4445 (6.3 CPU vulnerability mitigations). e2e/CI coverage for this profile is tracked in CMP-4510.

… 1.9) OpenSCAP node rule checking that the kubevirt cache directory (/var/run/kubevirt-private/) has mode 0755 or more restrictive. Uses the file_permissions template, which passes when the directory is absent (compliant by default on non-virt nodes). Validated on a live cluster: directory absent = PASS, directory with 0777 = FAIL, directory with 0755 = PASS.
