Abstract: Techniques for managing the migration of data from one virtual machine to another using volume snapshotting and sub-file cloning are described. According to exemplary embodiments, data including a header and content is stored on a storage volume associated with a first virtual machine. The header is converted to be compatible with a second virtual machine, and the storage volume is snapshotted to provide a read-only representation of the storage volume at the time that the snapshot was created. New data is created using the converted header and a pointer to the location of the data inside the volume snapshot. Using the exemplary techniques described herein, data can be migrated from one virtual machine to another in constant time, and data access is more robust because the pointer refers to the volume snapshot.

Abstract: Exemplary embodiments provide techniques for managing VM migrations that use relatively simple and uncomplicated commands or APIs that can be executed through scripts or applications. Configuration and preparation for the conversion may be addressed by one set of command-lets or APIs, while the conversion itself is handled by a separate set of command-lets or APIs, which allows the conversion command-lets to be uncomplex and to require little input. Moreover, the architecture-specific commands can be largely abstracted away, so that the configuration and conversion processes can be carried out through straightforward general commands, which automatically cause an interface (e.g., at the conversion server) to call upon any necessary architecture-specific functionality. Still further, the information that must be entered by a user may be kept to a minimum, because the initial configuration information may be used by the system to automatically discover additional information that is needed to perform the conversion.
