  • Virtual machine management using partially offloaded virtualization managers
    Patent number: 11429414
    Abstract: An opportunistic hypervisor determines that a guest virtual machine of a virtualization host has voluntarily released control of a physical processor. The hypervisor uses the released processor to identify and initiate a virtualization management task which has not been completed. In response to determining that at least a portion of the task has been performed, the hypervisor enters a quiescent state, releasing the physical processor to enable resumption of the guest virtual machine.
    Type: Grant
    Filed: November 9, 2018
    Date of Patent: August 30, 2022
    Assignee: Amazon Technologies, Inc.

  • Memory allocation techniques at partially-offloaded virtualization managers
    Patent number: 11068277
    Abstract: An offloaded virtualization management component of a virtualization host receives an indication from a hypervisor of a portion of main memory of the host for which memory allocation decisions are not to be performed by the hypervisor. The offloaded virtualization management component assigns a subset of the portion to a particular guest virtual machine and provides an indication of the subset to the hypervisor.
