MEMORY MANAGEMENT IN A VIRTUAL MACHINE BASED ON PAGE FAULT PERFORMANCE WORKLOAD CRITERIA

摘要

Embodiments of the present invention address deficiencies of the art in respect to virtualization and provide a novel and non-obvious method, system and computer program product for monitoring and managing memory used in a virtualized computing environment. In this regard, a method for monitoring and managing memory used by a virtual machine in a virtualized computing environment can include counting page fault occurrences in a guest operating system (OS) executing in the VM, pinning additional physical memory to the VM along with initiating a hot-add event to the guest OS executing in the VM, responsive to exceeding a page fault allowance threshold in order to mitigate system degradation in the VM based on page fault occurrences.
