摘要：One embodiment of the system disclosed herein facilitates reduction of latencyassociated with accessing content of a memory page that has been swapped out by aguest operating system in a virtualized computer system. During operation, a hypervisor
detects an I/O write command issued by the guest operating system at a swap locationwithin the guest operating system's swap file and records the swap location. Thehypervisor then prefetches contents of a page stored at the swap location within theguest operating system's swap file into a prefetch cache in host machine memory.Subsequently, the hypervisor detects an I/O read command issued by the guestoperating system at the swap location within the swap file. In response, the hypervisorprovides contents of the page to the guest operating system from the prefetch cache,thereby avoiding accessing the guest operating system's swap file.
