Abstract
An approach is provided in a hypervised computer system where a page table request is at an operating system running in the hypervised computer system. The operating system determines whether the page table request requires the hypervisor to process. If the determination reveals that the page table request requires the hypervisor, then the hypervisor is used to handle the request. However, if the determination reveals that the page table request does not require the hypervisor, then an indicator included in a page table entry corresponding to the request is read to determine if the page table entry is controlled by the operating system or the hypervisor. The operating system is able to update the page table entry if the indicator identifies the page table entry as being operating system controlled.
