Abstract
Systems and methods for enhancing efficient memory swap for virtual machines. An example method may comprise: receiving, by a hypervisor running on a host computer system, a request, from a virtual machine managed by the hypervisor, to write to a virtual disk a content of a memory page identified by a guest physical address (GPA); detecting, by the hypervisor, that the content of the memory page is stored on a storage device; storing, on the virtual disk, an identifier of a location of the content of the memory page on the storage device; and un-mapping the GPA from the storage device.
