A small update to my tests:
Environment was in VM VirtualBox.
Aonther Test with Ubuntu in VirtualBox with Kernel version:
2.6.32-25-generic
allowed me to execute the commands mentioned above to create hierarchical cgroups. Could this feature have been intentionally disabled in the more recent Kernel version or fedora?


Regards,

Simon
