there is a page already that covers the difference in greater details and w/o mistakes
== Comparison == Many may wonder what exactly the difference between OpenVZ and Virtuozzo is.<br/>Virtuozzo is based off OpenVZ, which means it adds a few features. Which are that? * Management interface (GUI)* Resource management* SLM memory management, while OpenVZ uses UBC ("Unified Buffer Cache"), #REDIRECT [[OpenVZ vs. Virtuozzo#SLM vs. UBC|see below for a comparison]].* VZFS (allows for disk and memory savings very similiar to Linux-VServer's copy-on-write system called "unification")* Commercial support OpenVZ is mostly run by Parallels (owner of Virtuozzo) employees, who maintain OpenVZ as the core functionality of Virtuozzo. == SLM vs. UBC ==An example would be: With UBC a VPS may be limited to 128 iptables entries. With SLM you can create thousands of iptables entries up to their global RAM limit.See bottom of http://www.tektonic.net/vz.html for a description of the SLM technology.
