Virtual machine image distribution network

摘要

Virtual machine images are distributed to, and retrieved from an image distribution network. A virtual machine image is received on the image distribution network and divided into chunks with a unique resource identifier created for each of the chunks. A virtual machine image reassembly file is created. Each of the chunks is assigned a unique resource locator address. An image distribution network server maintains a mapping between unique resource identifier for each of the chunks and the unique resource locator address. When a request to download a virtual machine image is received, chunks of the virtual machine image that are locally present are identified. Chunks of the virtual machine image that are not locally present are mapped to unique resource locator addresses in the image distribution network. When a sufficient number of chunks has been retrieved to instantiate the virtual machine image, the virtual machine image is instantiated.

主权项

1. A computer implemented method for distributing a virtual machine image to an image distribution network, the method comprising:
receiving, by a computer, the virtual machine image for publication on the image distribution network; dividing, by the computer, the virtual machine image into chunks; creating, by the computer, a unique resource identifier for each of the chunks; and creating, by the computer, a virtual machine image reassembly file for the virtual machine image, wherein the unique resource identifier for each of the chunks of the virtual machine image is prioritized in an order within the virtual machine image reassembly file based on a temporal access sequence pattern of the chunks by a running virtual machine, and wherein the unique resource identifier for each of the chunks is associated with one or more unique resource identifiers of other chunks based on a chunk access pattern between the chunks of the virtual machine image.
