Abstract:
1. A method of distributed virtual machine (VM) image management in a cloud computing environment, the method comprising: receiving in a hypervisor executing in memory of a host computer, a request for VM image data for a portion of a VM image; determining whether or not the requested VM image data is present in either a local cache of the hypervisor of the host computer or in a cache of a hypervisor of a peer host; retrieving the requested VM image data from a VM image seed in a remote data store in the cloud computing environment only when it is determined that the VM image data neither is present in the local cache of the hypervisor of the host computer nor is present in the cache of the hypervisor of the peer host; and, caching in the local cache of the hypervisor of the host computer the VM image data retrieved from the cache of the hypervisor of the peer host in response to a determination that the VM image data had been previously retrieved from the cache of the hypervisor of the peer host a threshold number of times.
