SWsoft Parallels has today launched the finalized version of its anti-hypervisor approach to virtualization, Virtuozzo Containers 4.0. It also appears the company is officially SWsoft no longer. Banish the name from your mind.

A shiny new logo constructed, voilà:

While big name virtualization houses run multiple operating systems on a single server, Virtuozzo divides a single OS into different "containers." In a nutshell, it virtualizes the OS rather than the hardware.

If you missed our ever-intrepid coverage of the Virtuozzo 4.0 beta (http://www.theregister.co.uk/2007/09/14/swsoft_parallels_virtuozzo/), here are the bullet points of enhancements:

• Support for Windows Server 2003 and Red Hat Enterprise Linux clustering services, and backup enhancements.
• Resource controls such as setting limits on bursts of CPU activity.
• Real-time optimization of hardware resources, and an improved Virtuozzo file system to more effectively utilize hard disk resources

Virtuozzo Containers 4.0 is available now at $2,500 per dual CPU. ®
