![]() Connectix sold versions of Virtual PC bundled with a variety of guest operating systems, including Windows, OS/2, and Red Hat Linux. The first version of Virtual PC designed for Windows-based systems, version 4.0, was released in June 2001. ![]() Virtual PC was originally developed as a Macintosh application for System 7.5 and released by Connectix in June 1997. Virtual PC by Connectix Connectix Virtual PC version 3 in Mac OS 9, running a Brazilian Portuguese edition of Windows 95 Starting in Windows 8, Microsoft replaced Virtual PC with Hyper-V. The earlier Microsoft versions which run on older versions of Windows were still available and support operating systems older than Windows XP. Windows Virtual PC only runs on Windows 7. History Ĭonnectix Virtual PC, Microsoft Virtual PC 2004, Microsoft Virtual PC 2007, and Windows Virtual PC are successive versions of the same software. Windows Virtual PC does not officially support MS-DOS or operating systems older than Windows XP Professional SP3 as guests. In 2009, Microsoft released Windows Virtual PC, which is only compatible with Windows 7 hosts, and is the technical foundation for the latter's Windows XP Mode. In August 2006, Microsoft announced the Mac version would not be ported to Intel-based Macs, effectively discontinuing the product as PowerPC-based Macs would no longer be manufactured. In July 2006, Microsoft released the Windows version free of charge. After Microsoft acquired Virtual PC from Connectix in 2003, the program was renamed Microsoft Virtual PC. Version 4 was released in 2000 for both Mac OS and Windows, and version 5 (2001) added support for Mac OS X hosts. ![]() Until version 4, Virtual PC only supported Classic Mac OS hosts. The Mac version was discontinued in 2006 following the Mac transition to Intel, while the Windows version was discontinued in 2011 in favour of Hyper-V. It was created by Connectix in 1997 and acquired by Microsoft in 2003. Virtual PC is an x86 emulator for PowerPC Mac hosts and a virtualization app for Microsoft Windows hosts. For the generic term, see Virtual machine. Such systems also provide app-by-app insights into cost, application performance, resource usage, and development processes.This article is about the virtualization software by Microsoft. ![]() The system's granular parsing of resources provides detailed visibility into systems. Virtual machine-based systems are designed to improve the efficiency of a host. Multiple virtual machines, even those with different operating systems, can be run simultaneously and independently within the same host computer. When this virtual machine is deployed to a host computer, software called a hypervisor reads the description and provides the requested compute resources. How does a virtual machine work?Ī virtual machine packages an operating system and application with a description of the compute resources needed to run it, such as the CPU, memory, storage, and networking. This approach has many advantages, but it takes work to make sure that deployments and resources are right-sized and that costs don't escalate. Many enterprise systems use third-party cloud computing providers for most of their internet-connected resources. Without a system for easy management, scaling, and responding to new business objectives, even just maintaining visibility becomes a burden on IT capabilities. Some enterprise systems may have hundreds or even thousands of apps and computing deployments. Virtual machines make it possible to update a single application without having to shut down the server and impacting all the applications running on the server. An error or breach in one app might leverage codependencies to do more damage. Virtual machines can also reduce downtime caused by maintenance or updates. ![]() The company can then incur a fraction of the hardware costs while also reducing space and power requirements.Īs enterprise deployments expand to satisfy the needs of dynamic mobile applications and flexible work arrangements, virtual machines can help manage costs for computing environments. This consolidation of underutilized servers helps organizations improve operational efficiency and reduce costs.įor example, instead of 20 applications running on 20 servers with each server at a low utilization rate, an organization can place 20 virtual machines on a single server. Virtual machines are intended to increase server utilization by running more applications per server. What problems can virtual machines solve? ![]()
