Virtuozzo is a privately held software company, specializing in virtualization software. It used to be a part of the Parallels company, but became an independent business entity in 2016.[1] Virtuozzo developed the first commercially available operating system-level virtualization container technology in 2000 which was open-sourced in 2005 in the form of OpenVZ.[2]

Company history[edit]

The company was founded in 1997 under the name SWsoft and maintained its headquarters in Herndon, Virginia with additional offices throughout North America, Europe, and Asia. Its research and development offices were located in Moscow, Russia, and it had sales offices in Germany and Singapore. In January 2002, Virtuozzo 2.0 containers virtualization solution was released. In 2003, SWsoft acquires makers of Confixx and Plesk web hosting products,[3] and got more offices in Germany and Novosibirsk, Russia. In December 2007, after acquisition of Parallels, Inc., a company announced its plans to change its name to Parallels and ship its products under the Parallels brand name.[4]

In 2015–2016, Parallels has spun off Odin, Plesk, and Virtuozzo, so that the virtualization and storage unit became a separate company.

Virtuozzo is an operating system-level server virtualization solution designed to centralize server management and consolidate workloads, which reduces overhead by reducing the number of physical servers required. Organizations use Virtuozzo for server consolidation, disaster recovery, and server workload agility. Virtuozzo does not generate a virtual machine that resides on a host OS so that users can run multiple operating systems. Instead it creates isolated virtual private servers (VPSs) on a single physical server. For instance, the software can run multiple Linux VPSs, but not Linux and Windows at the same time on the same server. Each VPS performs exactly like a stand-alone server and can be rebooted independently.

Virtuozzo for Linux became available in 2001 while a version that supports 32- and 64-bit microprocessors became available in 2005.[5] Linux architectures that support Virtuozzo for Linux are x86, ia64, AMD64, EM64T, and Itanium. Virtuozzo for Linux enables multiple Linux distributions to exist simultaneously on one server.[6] It is based on OpenVZ, a Linux-based OS-level virtualization technology, which allows a physical server to run multiple isolated operating system instances. In 2005, the company updated Virtuozzo to support 64-bit x86 processors.[7] Virtuozzo requires at least a Pentium III server with at least 1 GB of memory and 4 GB available hard drive. Virtuozzo’s management tools will be compatible with Microsoft’s Viridian and Virtual Server software.
