DE-DUPLICATED VIRTUAL MACHINE IMAGE TRANSFER
First Claim
1. A method for copying a first virtual machine image and a second virtual machine image from a source memory to a destination memory, the method comprising:
- copying a first block corresponding to the first virtual machine image from an interim memory to the destination memory, wherein the interim memory includes de-duplicated data that is present in the first virtual machine image and the second virtual machine image;
identifying a second block in the interim memory that corresponds to the second virtual machine image after copying the first block;
storing the second block in a buffer;
identifying a third block in the interim memory that corresponds to the first virtual machine image after storing the second block; and
copying the third block from the interim memory to the destination memory.

Abstract
Technologies are generally described for a system and method effective to copy virtual machine images from a source to a destination memory. A processor may copy a first block corresponding to a first virtual machine image from an interim memory to the destination memory. The interim memory may include de-duplicated data present in the first and the second virtual machine images. The processor may identify a second block in the interim memory that corresponds to the second virtual machine image and store the second block in a buffer. The processor may identify a third block in the interim memory that corresponds to the first virtual machine image and copy the third block from the interim memory to the destination memory.

15. A system effective to copy a first virtual machine image and a second virtual machine image from a source memory to a destination memory, the system comprising:
-
an interim memory; and a processor configured to communicate with the interim memory and configured to communicate with the source memory and the destination memory, the processor effective to; copy a first block corresponding to the first virtual machine image from an interim memory to the destination memory, wherein the interim memory includes de-duplicated data present in the first and the second virtual machine images; identify a second block in the interim memory that corresponds to the second virtual machine image after performance of the copy of the first block; store the second block in a buffer; identify a third block in the interim memory that corresponds to the first virtual machine image after storage of the second block; and copy the third block from the interim memory to the destination memory. - View Dependent Claims (21, 23, 24, 25, 26)

28. A method for copying a first virtual machine image and a second virtual machine image from a source memory to a destination memory, the method comprising:
-
identifying duplicated data, wherein the duplicated data is present in the first and second virtual machine images; copying the duplicated data from the source memory to an interim memory to produce de-duplicated data and an image block map; generating a file map based on the image block map, wherein the file map identifies blocks in the interim memory and virtual machine images corresponding to the blocks; copying a first block corresponding to the first virtual machine image from the interim memory to the destination memory; identifying a second block in the interim memory that corresponds to the second virtual machine image; storing the second block in a buffer; identifying a third block in the interim memory that corresponds to the first virtual machine image; and copying the third block from the interim memory to the destination memory; wherein the file map includes a first file corresponding to the first virtual machine image; a second file corresponding to the second virtual machine image; wherein the first file includes two or more regions, each region includes an identification of consecutive blocks of the de-duplicated data corresponding to the first virtual machine image; an indication of whether blocks are stored in the source memory, destination memory, and/or the buffer; and a region counter, the region counter effective to indicate a number of the second blocks that are stored in the buffer. - View Dependent Claims (29, 30)
