Doc Type: Known Issue
Doc Text:
The way cgroups are managed for `libvirt` changed between RHEL releases. As a result, `virsh cpu-stats` is not an officially supported part of the Red Hat OpenStack Platform (RHOSP) product. The functionality is provided by the underlying version of `libvirt` received from RHEL. Greenfield RHOSP 17.x is only supported on RHEL 9, which uses cgroups v2. The cgroups v2 API does not provide the API required to support the `virsh cpu-stats` API and this functionality is unavailable when using 17.1 on RHEL 9. + RHOSP 17.1 on RHEL 8, supported during mixed RHEL upgrades from 16.2, has been updated to make virsh cpu-stats functional while running on rhel 8.4. As a result, virsh cpu-stats functionality has been restored on RHEL 8 hosts but is unavailable on fully upgraded RHEL 9 hosts.
