Abstract
Methods, systems, and computer program products are included for de-duplicating one or more memory pages. A method includes receiving, by a hypervisor, a list of read-only memory page hints from a guest running on a virtual machine. The list of read-only memory page hints specifies a first memory page marked as writeable. The method also includes determining whether the first memory page matches a second memory page. In response to a determination that the first memory page matches the second memory page, the hypervisor may deduplicate the first and second memory pages.
