Abstract: Techniques that enable a hypervisor to (1) maintain shared memory pages and (2) handle memory accounting for VMs that are suspended to and resumed from the volatile memory of a host system are provided. Regarding (1), the hypervisor can maintain shared memory pages in volatile memory across the suspend-to-memory and resume-from-memory operations, without having to save their reference counts. Regarding (2), the hypervisor can keep track of the volatile memory reserved and consumed by VMs as they are suspended and resumed, without erroneously double counting that memory.

Abstract: Systems and methods are described for encrypting a swap file in a computer system. The swap file can be encrypted by a background process executing on the computer system. Processing of paging swapping operations occurs independently and separately of the background encryption of the swap file. Processing a page swapping operation can include decrypting or encrypting data to be swapped involved in the paging operation depending on the paging operation and whether or not the data to be swapped is encrypted or not.
