virtual hard disk (vhd) is a file format standard which maps logical hard disk contents to a physical disk image format, which can then be more efficiently stored in a variety of different storage types, such as file systems or logical volumes.

vhds are container files storing block metadata alongside a virtual disk's contents, in a single disk image. the metadata enables advanced storage backend capabilities, such as thin provisioning, disk image snapshotting, and coalescing of differencing disks.

this package contains the runtime vhdio library.
