Virtuozzo 3.0 for Linux Service Pack 1

HERNDON, Va.– SWsoft, a recognized leader in automation and virtualization software, today announced updates for the Linux and Windows versions of its Virtuozzo server virtualization software that dramatically improve networking management and provide greater support for Linux and Windows applications.

Both the Virtuozzo 3.0 for Linux Service Pack 1 and Virtuozzo 3.5.1 for Windows Service Pack 1 deliver advanced networking features including:

· Ethernet layer network adapter support - enables a virtual environment (VE) to run any Ethernet dependent application or service;

· VLAN support - allows set up of a virtual networking infrastructure that meets strict security requirements with complete network traffic isolation via support for virtual environment network adapters;

· Improved CPU management - the Linux update enables system administrators to assign any number of virtual CPUs, up to the number of physical CPUs available. The Windows update includes a new CPU scheduler to provide better isolation and enables strict CPU upper limits for each virtual environment.

“These updates to our Virtuozzo operating system-level virtualization technology provide significant improvements in terms of performance, scalability and security for our customers,” said Kurt Daniel, vice president of marketing and alliances, SWsoft. “Wider application support and advanced networking deliver greater flexibility and make it easier and more cost-efficient to create and manage Virtuozzo-based virtual servers.”

The Windows update also includes support for Citrix Presentation Server, which now can be directly installed in a virtual environment without any special configuration.

Operating System-Level Virtualization
With SWsoft Virtuozzo operating system (OS)-level server virtualization technology, a single Linux or Windows OS instance can be dynamically partitioned into multiple, highly-efficient virtual environments (VEs).

Virtuozzo is the first and only virtualization technology that addresses the challenge faced by today’s datacenters of operating systems sprawl where a number of different operating systems require support, maintenance and updating. Virtuozzo provides efficiency and manageability that result in the lowest total cost-of-ownership and fastest ROI for customers.

Virtuozzo is growing fastest among all vendors — 98 percent — in the hot overall market for virtualization technology, according to industry analyst firm IDC. (IDC Report: Worldwide Virtual Machine Software 2005 Vendor Shares, September 2006)
