SYSTEM AND METHOD FOR MANAGING MEMORY IN VIRTUAL MACHINES

Abstract:

A system and method include managing allocation of host physical memory to a guest physical memory of a virtual machine running on a computing node. The node includes hardware resources that are mapped the guest physical memory by a hypervisor. The hypervisor allocates a first amount of the host physical memory to the guest physical memory. The hypervisor also receives first page fault information. The hypervisor determines, based on the first page fault information, a first page fault rate. The hypervisor also determines that the first page fault rate is greater than a threshold rate, and allocates a second amount, greater than the first amount, of the host physical memory to the guest physical memory.
