Shared Features

Virtual PC and Virtual Server share a number of features in common. These include the following:
• Basic file architecture. Both Virtual PC and Virtual Server use the same file types for configuration and resource files. For example, virtual machine configuration files are .vmc files, virtual hard disk files are .vhd files, and saved state files are .vsv files. This common file architecture allows virtual machines (within certain limitations) to be shared between Virtual PC and Virtual Server.
• Networking. Both Virtual PC and Virtual Server allow networking between virtual machines and physical machines. With Virtual Server, however, you can also create and configure virtual networks.
• Virtual machine control options. Options for controlling virtual machines, such as starting, stopping, shutting down, and saving state are the same for Virtual PC and Virtual Server.
• Disk features. Undo and differencing disks are available in both Virtual PC and Virtual Server.
