摘要： An event calling for a migration of a workload from a source processor set of processing units to a target processor set of processing units is detected. Processes of the workload are allocated to a second processor set of processing units so that some workload processes are executed on the source processor set and some workload processes are executed on a second processor set of processor units. Then, some workload processes are allocated to the second processor set so that no workload process is executing on the source processor set and at least some of said processes are executing on the second process set. The second processor set can be the target processor set or an intermediate processor set from which the workload is migrated to the target processor set.

摘要： A computer system comprises a physical computer and a virtual machine monitor executable on the physical computer and configured to create an emulation of at least one guest operating system adapted to control the physical computer. The computer system further comprises a host executable on the physical computer that manages physical resources coupled to the physical computer on behalf of the virtual machine monitor and the at least one guest operating system. The host is adapted to virtualize a Peripheral Component Interconnect (PCI) configuration address space whereby the at least one guest operating system controls PCI input/output (I/O) devices directly and in absence of I/O emulation.

摘要： Various embodiments of the present invention are directed to efficient provision, by a virtual-machine monitor, of a virtual, physical memory interface to guest operating systems and other programs and routines interfacing to a computer system through a virtual-machine interface. In one embodiment of the present invention, a virtual-machine monitor maintains control over a translation lookaside buffer (“TLB”), machine registers which control virtual memory translations, and a processor page table, providing each concurrently executing guest operating system with a guest-processor-page table and guest-physical memory-to-physical memory translations. In one embodiment, a virtual-machine monitor can rely on hardware virtual-address-translation mechanisms for the bulk of virtual-address translations needed during guest-operating-system execution, thus providing a guest-physical memory interface without introducing excessive overhead and inefficiency.

摘要： A system and corresponding method virtualizes a real-time clock in the presence of a time-disrupting event. The real-time clock is used with physical machines and includes a single time source within each of the physical machines. The system is implemented in one or more programmable devices, which may be hardware and/or software devices, or a combination of hardware and software devices. The physical machines include one or more virtual machines. The system includes an offset module that determines a time difference offset between a virtual interrupt timer counter (ITCV) associated with a virtual machine and a physical interrupt timer counter (ITCP) associated with a physical machine. The system also includes a virtual machine monitor that computes one or more first time adjustments based on the offset and applies the adjustments to eliminate at least a first part of the offset.

摘要： A software monitor, interposed between the hardware layer of a computer system and one or more guest operating systems, constructs and maintains a guest-physical-address-to-host-physical-address map for each guest operating system, and maintains a virtual memory addressing context for each guest operating system that may include a virtual-hash-page table for each guest operating system, the contents of translation registers for each guest operating system, CPU-specific virtual-memory translations for each guest operating system, and the contents of various status registers. The monitor runs at the highest privilege level provided by the hardware system, intercepting attempts to execute privileged instructions by guest operating systems, and simulates or enhances certain of the privileged instructions related to virtual-memory addressing in order to construct and maintain the guest-physical-address-to-host-physical-address map and to provide each guest operating system with the illusion that the guest operating system is executing as the most privileged process on a virtual machine.
