Abstract
A hypervisor receives a memory page checksum from a guest operating system, which corresponds to a page of memory utilized by the guest. Next, the hypervisor proceeds through a series of steps to detect that the memory page checksum matches a checksum value included in a checksum entry item, which includes an identifier of a different guest. In turn, the hypervisor shares the page of memory between the guest and the different guest in response to detecting that the memory page checksum matches the checksum value included the checksum entry item.
