  • Virtual machine migration detection by a hosted operating system
    Patent number: 11520612
    Abstract: In an embodiment, a guest operating system (OS) running on a virtual machine (VM) detects a VM migration, where the embodiment comprises storing, by the guest OS, a VM identifier (VMID) provided by the VM and a first host identifier (HID) provided by a host computer system in a computer memory. The embodiment also comprises determining, by the guest OS, that the VM performs migrations that are transparent to the guest OS. The embodiment further comprises detecting, by the guest OS, that the VM has been migrated based on a comparison of the first HID to a second HID provided to the guest OS in response to an HID request from the guest OS.

  • Operating system code patching during live migration
    Patent number: 11436043
    Abstract: For a process of an operating system, it is detected that a live migration has occurred, the live migration comprising a change in a hardware characteristic of a computer system on which the process executes. A first message is broadcast to a set of processors, the first message causing each processor in the set of processors to enter a waiting state. While each of the set of processors is in the waiting state, a portion of a set of program instructions of the operating system is modified.
