1. A method for converting a source storage object for use by a virtual machine comprising: requesting a size of the source storage object, the source storage object having a set of data blocks on a storage system, the source storage object having a one or more pointers directed to the set of data blocks; creating a destination storage object having the size on the storage system, the destination storage object including one or more reserved ranges of data blocks according to a file system stored on the storage system; copying the one or more pointers of the source storage object to the destination storage object to reference data blocks of the set of data blocks of the source storage object such that a logical sequence of the data blocks in the source storage object is maintained in the destination storage object; and configuring the destination storage object to a format for the virtual machine.
