Comparison
Many may wonder what exactly the difference between OpenVZ and Virtuozzo is.
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"), 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.
