  • Impeding progress of malicious guest software
    Patent number: 8763115
    Abstract: One embodiment of the present invention is a method of operating a virtualization system, the method including: (a) instantiating a virtualization system on an underlying hardware machine, the virtualization system exposing a virtual machine in which multiple execution contexts of a guest execute; (b) monitoring the execution contexts from the virtualization system; and (c) selectively impeding computational progress of a particular one of the execution contexts.
    Type: Grant
    Filed: March 19, 2008
    Date of Patent: June 24, 2014
    Assignee: VMware, Inc.
    Inventors: Dmitriy Budko, Xiaoxin Chen, Oded Horovitz, Carl A. Waldspurger
  • Monitoring execution of guest code in a virtual machine
    Patent number: 8402441
    Abstract: A method is provided for monitoring registered code in a virtual machine of a virtualization system. The method includes instantiating a guest in the virtual machine of the virtualization system and monitoring execution of code registered for monitored execution in an execution context of the guest. The monitoring is performed by the virtualization system and is hidden from computations of the guest.

  • Selective descheduling of idling guests running on a host computer system
    Patent number: 8352944
    Abstract: Guests, such as virtual machines, that are running on a host hardware platform are selectively descheduled when an idling condition is detected. An example of the idling condition is that the guest has been executing instructions in an idle loop for more than a threshold period. Guest instructions may be evaluated for the idling condition in conjunction with binary translation.

  • Forcing registered code into an execution context of guest software
    Patent number: 8250519
    Abstract: A method is provided for executing guest computations in a virtual machine of a virtualization system and forcing execution of registered code into an execution context of the guest. The forcing is performed from the virtualization system based on an execution trigger monitored without reliance on functionality of the guest software.

  • FORCING REGISTERED CODE INTO AN EXECUTION CONTEXT OF GUEST SOFTWARE
    Publication number: 20090055571
    Abstract: One embodiment of the present invention includes a method for: (a) executing guest computations in a virtual machine of the virtualization system; and (b) forcing execution of registered code into an execution context of the guest, wherein the forcing is performed from the virtualization system based on an execution trigger monitored without reliance on functionality of the guest software.
