When libvirt is used from unconfined services you see denials like
avc: denied { search } for comm="rpc-virtqemud" name="78700" dev="proc" scontext=system_u:system_r:virtqemud_t:s0 tcontext=system_u:system_r:unconfined_service_t:s0 tclass=dir permissive=1
avc: denied { read } for comm="rpc-virtqemud" name="stat" dev="proc" scontext=system_u:system_r:virtqemud_t:s0 tcontext=system_u:system_r:unconfined_service_t:s0 tclass=file permissive=1
avc: denied { open } for comm="rpc-virtqemud" path="/proc/78700/stat" dev="proc" scontext=system_u:system_r:virtqemud_t:s0 tcontext=system_u:system_r:unconfined_service_t:s0 tclass=file permissive=1
