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： A method for mapping an active entry within a virtually hashed page table is disclosed. An active entry within a virtually hashed page table is populated. A link table for locating a link at an offset from an active entry is maintained. This link table continues to be maintained as a valid link table until an occupied head bucket threshold is exceeded or a collision has occurred.

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.
