Setting up a Virtual Machine (VirtualBox) We'll show you how to set up a virtual machine using VirtualBox. VirtualBox is one of the most popular virtual machine programs since it is free, open source, and available on all the popular operating systems. Some options are VirtualBox (Windows, Linux, Mac OS X), VMware Player (Windows, Linux), VMware Fusion (Mac OS X) and Parallels Desktop (Mac OS X). There are many different virtual machine programs you can use. Also, when many virtual machines are running at the same time on a single computer, performance can become unstable. Since hardware resources are indirect, they are not as efficient as a physical computer. There are a few drawbacks with virtual machines. Each piece of virtual hardware is mapped to real hardware on the host computer. Virtual machines have virtual hardware, including CPUs, memory, hard drives, and more. Often a server will use a program called a hypervisor to manage multiple virtual machines that are running at the same time. Virtual machines are also used to quickly set up software with an image, access virus-infected data, and test other operating systems.Ī single physical computer can run multiple virtual machines at the same time. For instance, if you are using a Mac computer you can run Windows programs inside a Windows virtual machine on the Mac computer. Virtual machines are often used for running software on operating systems that software wasn't originally intended for. This means that nothing that runs on the virtual machine can impact the host computer. Virtual machines are sandboxed from the host computer. It is basically a way to create a computer within a computer.Ī virtual machine runs in a window on the host computer and gives a user the same experience they would have if they were using a completely different computer. Virtual PC provides additions that you install in a guest operating system to enable this functionality.A virtual machine is a program you run on a computer that acts like it is a separate computer. Users can copy, paste, drag, and drop between guest and host. The restoration process normally takes a few seconds-much faster than restarting the guest operating system. They can also save virtual machines to disk and restore them at a later time. They can pause individual virtual machines so they stop using CPU cycles on the physical computer. They simply click the window containing the virtual machine. Users switch between operating systems as easily as they switch between applications. StandardizationĬonfigure and test upgrades and installations on virtual machines, and then you can deploy throughout your company a standard configuration that avoids problems caused by minor differences between hardware platforms. The first time Virtual PC starts, it guides you through the process of creating the first virtual machine. Any administrator can run the Virtual PC guided setup program, and installation doesn’t require a reboot. Virtual PC has a number of settings that control how the product interacts with the physical computer, allocates resources, and so on. ConfigurabilityĪfter installing Virtual PC, you can configure it to suit your requirements. Virtual PC is perfect for any scenario in which you need to support multiple operating systems, whether you use it for tech support, legacy application support, training, or just for consolidating physical computers. You can run multiple operating systems at once on a single physical computer and switch between them as easily as switching applications-instantly, with a mouse click. Use virtual machines to run operating systems such as MS-DOS, Windows, and OS/2. Virtual PC lets you create separate virtual machines on your Windows desktop, each of which virtualizes the hardware of a complete physical computer.
