Abstract:
Systems and methods for memory page hints that account for multiple page sizes. An example method may comprise: determining, by a processing device executing a guest operating system, that a memory page size of the guest operating system is different from a memory page size of a hypervisor; adding, by the guest operating system, a guest memory page released by the guest operating system to a set of guest memory pages; determining in view of the memory page size of the hypervisor that the set of guest memory pages fills a hypervisor memory page; and providing an indication to the hypervisor that the hypervisor memory page is available for reuse.
