VHD File Format

Disk image file format used with Virtual Server and Hyper-V

VHD is the file extension for a disk image file format for storing the complete contents of a hard drive. VHD stands for virtual hard disk. The disk image, sometimes called a virtual machine, replicates an existing hard drive and includes all data and structural elements.

VHD is the format used for Virtual Server and Hyper-V hypervisors. The VMware counterpart to the VHD file format is the VMDK format.
