'''New [[Download/kernel/rhel6|RHEL6-based OpenVZ]] kernel''' has a new memory management model, which supersedes [[UBC|User beancounters]]. It is called '''VSwap'''.

With VSwap, there are two required parameters: <code>ram</code> and <code>swap</code> (a.k.a. <code>physpages</code> and <code>swappages</code>). All the other beancounters become optional.
