Abstract: When a process is swapped out of memory, a record of the sharable memory pages of the process is maintained. The sharable memory pages can then be repurposed. When the process is subsequently swapped back into memory, concurrently with the process running the sharable memory pages of the process are prefetched. If during this prefetching the process requests a memory page that is not currently in physical memory, a high priority I/O request is issued for that memory page. The high priority I/O request is placed at the front of an I/O queue, so the high priority I/O request is processed before the pending prefetch requests.

Abstract: A host machine having guest virtual machine physical memory backed by host virtual memory is described. The host machine includes host physical memory. The host machine further includes one or more guest virtual machines. Each of the guest virtual machines includes guest physical memory. The host machine further includes host virtual memory. The host machine further includes a data structure having a correlation of guest physical memory addresses to host virtual memory addresses and a data structure having a correlation of host virtual memory addresses to host physical memory addresses.

Abstract: In one embodiment, a memory management system temporarily maintains a memory page at an artificially high priority level. The memory management system may assign an initial priority level to a memory page in a page priority list. The memory management system may change the memory page to a target priority level in the page priority list after a protection period has expired.
