摘要： A system and method for allowing a virtual machine monitor to assume control of a system when the current privilege level of guest software meets a privilege level exiting criteria. The processor detects that the current privilege level meets the criteria and then transfers control from the guest software to the virtual machine monitor. The virtual machine monitor may decline to assume control for certain privilege level changes or values.

摘要： In some embodiments, the invention involves a system to deprivilege components of a virtual machine monitor and enable deprivileged service virtual machines (SVMs) to handle selected trapped events. An embodiment of the invention is a hybrid VMM operating on a platform with hardware virtualization support. The hybrid VMM utilizes features from both hypervisor-based and host-based VMM architectures. In at least one embodiment, the functionality of a traditional VMM is partitioned into a small platform-dependent part called a micro-hypervisor (MH) and one or more platform-independent parts called service virtual machines (SVMs). The micro-hypervisor operates at a higher virtual machine (VM) privilege level than any SVM, while the SVM and other VMs may still have access to any instruction set architecture (ISA) privilege level. Other embodiments are described and claimed.

摘要： In one embodiment, a method includes transitioning control to a virtual machine (VM) from a virtual machine monitor (VMM), determining that a VMM timer indicator is set to an enabling value, and identifying a VMM timer value configured by the VMM. The method further includes periodically comparing a current value of a timing source with the VMM timer value, generating an internal event if the current value of the timing source has reached the VMM timer value, and transitioning control to the VMM in response to the internal event without incurring an event handling procedure in any one of the VMM and the VM.

摘要： Embodiments of apparatuses, methods, and systems for delivering an interrupt to a virtual processor are disclosed. In one embodiment, an apparatus includes an interface to receive an interrupt request, delivery logic, and exit logic. The delivery logic is to determine, based on an attribute of the interrupt request, whether the interrupt request is to be delivered to the virtual processor. The exit logic is to transfer control to a host if the delivery logic determines that the interrupt request is not to be delivered to the virtual processor.

摘要： In one embodiment, the present invention includes a method of transitioning control to guest software in a virtual machine from a virtual machine monitor, receiving control following a transition from the virtual machine to the virtual machine monitor upon an event, and determining whether to modify a state of the guest code, a state of the virtual machine monitor or a state of controls. If such a determination is made, the state may be modified and control is transitioned back to the guest software.

摘要： In one embodiment, a method for supporting address translation in a virtual-machine environment includes creating a guest translation data structure to be used by a guest operating system for address translation operations, creating an active translation data structure based on the guest translation data structure, and periodically modifying the content of the active translation data structure to conform to the content of the guest translations data structure. The content of the active translation data structure is used by a processor to cache address translations in a translation-lookaside buffer (TLB).

摘要： Transitions among schedulable entities executing in a computer system are tracked in computer hardware or in a virtual machine monitor. In one aspect, the schedulable entities are operating system processes and threads, virtual machines, and instruction streams executing on the hardware. In another aspect, the schedulable entities are processes or threads executing within the virtual machines under the control of the virtual machine monitor. The virtual machine monitor derives scheduling information from the transitions to enable a virtual machine system to guarantee adequate scheduling quality of service to real-time applications executing in virtual machines that contain both real-time and non-real-time applications. In still another aspect, a parent virtual machine monitor in a recursive virtualization system can use the scheduling information to schedule a child virtual machine monitor that controls multiple virtual machines.

摘要： In one embodiment, a method for resolving address space conflicts includes detecting that a guest operating system attempts to access a region occupied by a first portion of a virtual machine monitor and relocating the first portion of the virtual machine monitor within the first address space to allow the guest operating system to access the region previously occupied by the first portion of the virtual machine monitor.
