Just to clarify, the OpenVZ kernel runs fine on RHEL(5&6) too. In fact I have a couple of RHEL hosts running OpenVZ. So far as resource management goes, in the EL6-based OpenVZ kernel, vSwap-based configuration/management is preferred whereas in the EL5-based kernel (which OpenVZ is EOL'ing in Oct. I think), user_beancounters are what you have. vzctl's resource management facilities do what the vast majority of container users need. vzctl-core is available for non-OpenVZ kernels but it is missing quite a few features compared to when run on an OpenVZ-based kernel. See: https://wiki.openvz.org/Vzctl_for_upstream_kernel I don't think it is well tested on upstream kernels.
