In some embodiments, a system comprises a hardware machine comprising an input/output (I/O) device; and a virtual machine monitor to interface the hardware machine and a plurality of virtual machines.

If the virtual machine is latency sensitive, then a second halt instruction is issued from the virtual machine monitor to halt a physical CPU on which the virtual CPU executes.

Machine-readable media, methods, and apparatus are described to change a first scheduler in the virtual machine monitor.

The computing system includes a virtual high-privilege mode in a trusted domain managed by the virtual machine monitor.

The virtual machine monitor implements multiple virtualization support processors that each provide for the comprehensive handling of potential virtualization exceptions.

In various embodiments, the first and second logic units may perform these functions independent of a VMM of the computing device.

A network delay aware Virtual Machine (VM) may be configured to adapt a Virtual Machine Monitor (VMM) to delay switching back to the network delay aware VM by a delay amount determined using a measured network delay.

The virtual machine monitor implements multiple virtualization support subsystems that each provide for the comprehensive handling of potential virtualization exceptions.

This layer includes the virtual machine monitor (VMM), which is responsible for virtualization, and the VMkernel.

Memory for the needs of certain components, such as the virtual machine monitor (VMM) and virtual devices, is fully reserved when a virtual machine is powered on.

The computer system includes a virtual machine monitor, a server operating system, a management agent module and at least one user operating system.

A virtual machine monitor (VMM) has access to underlying platform hardware in the system and may control physical resources in the platform.

The virtual machine monitor may also host a locking application for limiting the functionality of the computer if contractual terms of use are not met.

Both the metering and locking applications run at a higher privilege level than ring 0, at the same level as the virtual machine monitor.

If a memory permission violation occurs, control of the computing device is transferred to a virtual machine monitor to intervene prior to execution of the API function.
