US Patent 9940159 Facilitating hibernation mode transitions for virtual machines

Systems and methods for facilitating hibernation mode transitions for virtual machines. An example method comprises: responsive to determining that an active user session exists in a virtual machine operating in a hibernation state on a host computer system, disabling modifications of a hardware configuration parameter of the virtual machine; responsive to determining that the active user session has terminated, enabling modifications of the hardware configuration parameter of the virtual machine; and responsive to determining the hardware configuration parameter of the virtual machine has been modified, causing the virtual machine to discard, upon awakening, a previously saved memory state.
