Abstract: In one embodiment, a request to transition control to a virtual machine (VM) is received from a virtual machine monitor (VMM) and a determination is made as to whether the VMM has requested a delivery of a fault to the VM. If the determination is positive, the fault is delivered to the VM when control is transitioned to the VM.

Abstract: Methods and systems are provided to control the execution of a virtual machine (VM). A VM Monitor (VMM) accesses VM Control Structures (VMCS) indirectly through access instructions passed to a processor. In one embodiment, the access instructions include VMCS component identifiers used by the processor to determine the appropriate storage location for the VMCS components. The processor identifies the appropriate storage location for the VMCS component within the processor storage or within memory.

Abstract: 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.

Abstract: In one embodiment, a processor mode is provided for guest software. The processor mode enables the guest software to operate at a privilege level intended by the guest software. When the guest software attempts to perform an operation restricted by the processor mode, the processor mode is exited to transfer control over the operation to a virtual-machine monitor, which runs outside this processor mode.

Abstract: In one embodiment, fault information relating to a fault associated with the operation of guest software is received. Further, a determination is made as to whether the fault information satisfies one or more filtering criterion. If the determination is positive, control remains with the guest software and is not transferred to the virtual machine monitor (VMM).

Abstract: In one embodiment, a command pertaining to one or more portions of a register is received from guest software. Further, a determination is made as to whether the guest software has access to all of the requested portions of the register based on indicators within a mask field that correspond to the requested portions of the register. If the guest software has access to all of the requested portions of the register, the command received from the guest software is executed on the requested portions of the register.
