Doc Type:	Bug Fix
Doc Text:	Previously, libvirt made control group (cgroup) requests on files that it should not have. With older kernels, such nonsensical cgroup requests were ignored; however, newer kernels are stricter, resulting in libvirt logging spurious warnings and failures to the libvirtd and audit logs. The audit log failures displayed by the ausearch tool were similar to the following: root [date] - failed cgroup allow path rw /dev/kqemu With this update, libvirt no longer attempts the nonsensical cgroup actions, leaving only valid attempts in the libvirtd and audit logs (making it easier to search for real cases of failure).
