From: Jiri Denemark <jdenemar@redhat.com> Some CPU features may be enabled explicitly, but should not automatically become part of a host-model CPU. Users can now request such features to be shown in the host-model CPU in domain capabilities by VIR_CONNECT_GET_DOMAIN_CAPABILITIES_SUPPORTED_CPU_FEATURES flag.
