New  RHEL6-based OpenVZ  kernel has a new memory management model, which supersedes  User beancounters . It is called  VSwap . Now you can set two primary parameters:  physpages  and  swappages , while all the other beancounters become secondary. physpages This parameter limits the physical memory (RAM) available to processes inside a container. The  barrier  is ignored, and the  limit  sets the limit. Currently the user memory and the page cache are accounted into  physpages . swappages This parameter limits the amount of swap space which can be used for processes inside a container. The  barrier  is ignored, and the  limit  sets the limit. The sum of physpages.limit and swappages.limit limits the maximum amount of allocated memory which can be used by a container. When physpages limit is reached, memory pages belonging to the container are pushed out to so called virtual swap ( vswap ). The d...
