  • Patent number: 12182437
    Abstract: Systems and methods for creating virtual machine snapshots. An example method comprises: receiving a request to create a snapshot of a virtual machine running on a host computer system; protecting from modification a plurality of virtual memory pages of the virtual machine; responsive to detecting an attempt to modify a virtual memory page of the plurality of memory pages, copying the virtual memory page to a queue residing in a random access memory (RAM) of the host computer system; making the virtual memory page writable; retrieving the virtual memory page from the queue; writing the virtual memory page to a disk of the host computer system; and responsive to exhausting the queue, completing creation of the snapshot of the virtual machine.

  • Patent number: 10606493
    Abstract: A system and method is provided for managing memory allocated to a virtual machine running on a host platform. An exemplary method includes continuously calculating the amount of free physical memory of the host platform by subtracting the amount of physical memory currently used consumed by the host operating system from the total size of the physical memory on the host platform. Moreover, using the calculated amount of free physical memory, the method includes dynamically adjusting an overall limit of the physical memory that can be allocated to the virtual machine running on the host platform, and then allocating to the virtual machine an amount this allocated physical memory so that active pages can be stored in the allocated memory and directly accessed during operation by the virtual machine.
