Abstract
Disclosed is an improved approach to optimize link-based cloning in a virtualization architecture. In some approaches, each of the remote nodes is allowed to maintain its own snapshot of the linked/shared image. In this way, the processing power of each remote node can be used in a decentralized manner to administratively handle access to the shared data, rather than requiring the CPU resources of only the host node to centrally handle administrative access to the data. In addition, each of nodes can maintain copies of the shared image in a local cache. This allows the caching resources to also be decentralized, as each of the nodes can use its own caching resources to hold the shared data.
