Patent number: 10776020Abstract: Aspects of the disclosure provide for mechanisms for memory protection of virtual machines in a computer system. A method of the disclosure includes: obtaining, by a hypervisor, a guest page table associated with a virtual machine, wherein the guest page table comprises a first guest page table entry associated with a privilege flag indicating that a first virtual page of a guest memory of the virtual machine is accessible to unprivileged code; and in view of a determination that the virtual machine is running in a kernel mode, generating a first host page table in view of the guest page table, wherein the first host page table comprises a first host page table entry corresponding to the first guest page table entry, and wherein the first host page table entry is associated with a privilege flag indicating that the first virtual page is not accessible to the unprivileged code.Type: GrantFiled: August 13, 2018Date of Patent: September 15, 2020Assignee: Red Hat, Inc.Inventors: David Gilbert, Paolo Bonzini

Patent number: 10761676Abstract: A method, apparatus, and system for displaying information for an aircraft on display devices in a flight deck of the aircraft. A computer system in the aircraft identifies information used to operate the aircraft. The computer system selects a display configuration from a plurality of display configurations for the display devices based on a first set of tasks assigned to a pilot for a current flight and a second set of tasks assigned to a copilot for the current flight of the aircraft. The computer system displays the information in windows on display devices in the flight deck of the aircraft in the display configuration. The display configuration simplifies access to the information used by the pilot to perform the first set of tasks and the copilot to perform the second set of tasks.Type: GrantFiled: September 25, 2018Date of Patent: September 1, 2020Assignee: The Boeing CompanyInventors: Brian David Gilbert, John Wiedemann, Sherwin S.

Patent number: 10552230Abstract: A hypervisor of a source host receives a request to migrate a group of virtual machines that provide network function virtualization support (NFV) from the source host to a destination host. The hypervisor of the source host determines that a first virtual machine of the group of virtual machines being migrated to the destination host shares a memory space on the source host with the group of virtual machines on the source host. Upon receiving a request from a second virtual machine of the group of virtual machines on the source host to access a first memory page of the shared memory space on the source host that has been migrated to the destination host, the hypervisor of the source host initiates migration of the second virtual machine to the destination host.Type: GrantFiled: May 23, 2016Date of Patent: February 4, 2020Assignee: Red Hat Israel, Ltd.Inventors: Michael S. Tsirkin, David A. Gilbert

Patent number: 10503659Abstract: A system and methods for migrating a virtual machine (VM). In one embodiment, a hypervisor receives a request to migrate the contents of a memory of a source VM in a first physical memory area to a destination VM in a second physical memory area, where the first and second physical memory areas are disjoint. The hypervisor executes the destination VM in response to the request, and detects an access of a page of memory of the destination VM. The hypervisor determines, in view of a data structure maintained by a guest operating system executing in the destination VM, that a first page of a memory of the source VM in the first physical memory area is currently in use by the destination VM.Type: GrantFiled: April 2, 2018Date of Patent: December 10, 2019Assignee: Red Hat Israel, Ltd.Inventors: Michael Tsirkin, David A.

Publication number: 20180096610Abstract: A collision avoidance system comprises a pair of video cameras mounted to a vertical stabilizer of the aircraft, a machine vision processing unit, and a system to inform the pilots of a potential collision. The machine vision processing unit is configured to process image data captured by the video cameras using stereoscopic and structure from motion techniques to detect an obstacle that is near or in the path of the aircraft. Estimates of the range to the object and the rate of change of that range are computed. With the range and range rate, a time to collision can be estimated toward every point of the aircraft. A pilot warning can be sounded based on the nearness of the potential collision. A method of calibrating the video cameras using existing feature points on the top of the aircraft is initiated in response to power being turned on.Type: ApplicationFiled: September 30, 2016Publication date: April 5, 2018Applicant: The Boeing CompanyInventors: Gary Alan Ray, Brian David Gilbert
