摘要： Embodiments of apparatuses, methods, and systems for controlling virtual machines based on performance counters are disclosed. In one embodiment, an apparatus includes an event counter, a comparator, and virtualization control logic. The event counter is to keep an event count based on the number of occurrences of an event. The comparator is to determine whether the event count has reached a threshold value. The virtualization control logic is to transfer control of the apparatus from a guest to a host in response to the comparator determining that the event count has reached the threshold value.

摘要： Embodiments of apparatuses, methods, and systems for executing a protected device model in a virtual machine are disclosed. In one embodiment, an apparatus includes recognition logic, memory management logic, control logic, and execution logic. The recognition logic is to recognize an indication, during execution of first code on a virtual machine, that the first code is attempting to access a device. The memory management logic is to prevent the virtual machine from accessing a portion of memory during execution of the first code, and to allow the virtual machine to access the portion of memory in response to the indication. The control logic is to transfer control of the apparatus from the first code to second code stored in the portion of memory, without exiting the virtual machine. The execution logic is to execute the second code to model the device.

摘要： Methods and systems are provided to control transitions between a virtual machine (VM) and Virtual Machine Monitor (VMM). A processor uses state action indicators to load and/or store associated elements of machine state before completing the transition. The state action indicators may be stored in a Virtual Machine Control Structure (VMCS), predetermined, and/or calculated dynamically. In some embodiments, the values loaded can be directly acquired from the VMCS, predetermined and/or calculated dynamically. In some embodiments, the values stored may be acquired directly from machine state, predetermined and/or calculated dynamically.

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.
