Abstract
A method for reducing disk read rate by managing dataset mapping of virtual machine (VM) guest memory, comprising: monitoring a plurality of disk read write operations of a VM guest; updating a dataset mapping between disk blocks allocated to the VM guest and corresponding physical addresses of memory pages of the VM guest containing replica of data stored in the disk blocks, based on the plurality of disk read write operations; when identifying writing to one of the memory pages, removing a mapping of corresponding disk block and corresponding physical address of memory page; when reclaiming a mapped memory page of the VM guest by a host of the VM guest, discarding data contained in the memory page; and when the data is requested by the VM guest after it was reclaimed by said host, retrieving the data from corresponding disk block according to the mapping.
