Without going into great detail here, create a new VM by specifying the name of the VM, the location of the virtual hard disk and the.

Just follow these steps: Step #1 – Create and install the base image VM So how do we create one? Creating differencing hard disks is easy. The next time you start the virtual machine, it will be in a clean state ready for another test.Īs you’ve see, differencing virtual hard disks are a good method of sharing the same VM with many users, or share the same virtual hard disk with many VMs. For example, you can use undo disks to test a deployment scenario in a safe environment and delete the changes at the end of the session. Undo disks are convenient because they allow users to start with the exact same virtual disk every time.

At the end of the session when the user stops the VM, he or she can choose to save, commit, or delete the changes.

Virtual PC stores these changes in a separate temporary file called VirtualPCUndo_ VM-NAME_ DATE.vud

Undo disks – Undo disks allow users to delete any changes they make to the virtual hard disk during a session that lasts from the time the virtual machine is started until it is closed.

You can then configure Virtual PC to store any changes that the users make in local differencing virtual hard disks. Another example might be to store a parent virtual hard disk somewhere on the network and share it with many users. For example, you can build one instance of a given operating system, configure it as a parent disk, and then create many alterations of the same operating system by simply adding differencing virtual disks that rely on the parent disk. Virtual PC stores any changes to the virtual hard disk in the differencing virtual hard disk.

Differencing virtual hard disks – Differencing virtual hard disks allow multiple users and multiple virtual machines to use the same parent virtual hard disk at the same time.

Microsoft Virtual PC also supports two types of virtual hard disk that I want to talk about in this article: The virtual machine “sees” the virtual hard disk as a real hard disk, and is able to format it and install itself on it. When you work with Virtual Machines you must allocate at least one virtual hard disk per machine. We will deal with that product in a later article. Note that besides Virtual PC, Microsoft also offers a more robust product called Virtual Server 2005 R2.

You can download Microsoft Virtual PC 2007 for free from the following link: Both are free and both are good, but as far as I am concerned, the latest version, called Microsoft Virtual PC 2007, is my preferred VM tool for my own personal use. I will not go into the age-old fight on who’s best – Microsoft Virtual PC or VMWare’s software. Because a VHD is initialized when it is created, creating a large fixed-size VHD might take some time.As I mentioned in my “ Creating Virtual Machines with Microsoft Virtual PC 2007” article, Microsoft Virtual PC is one of the top contenders in a growing line of Virtual Machine utilities.The minimum size for a VHD is 3 megabytes (MB).The path specifying the location for the VHD must be fully-qualified and cannot be in the \Windows directory.Detaching a VHD does not delete the VHD or any data stored in it. Right-click the disk, select Detach VHD, and then click OK. To detach the VHD, making it unavailable: Specify the location of the VHD, using a fully-qualified path. To make a VHD available for use (either one you have just created or another existing VHD):

In Virtual hard disk format, select Dynamically expanding or Fixed size, and then click OK. In the Create and Attach Virtual Hard Disk dialog box, specify both the location on the physical computer where you want the VHD file to be stored, and the size of the VHD.

You must be a member of the Backup Operators or Administrators group, at minimum, to complete these steps.
