摘要： Technologies for scheduling workload submissions for a graphics processing unit (GPU) in a virtualization environment include a GPU scheduler embodied in a computing device. The virtualization environment includes a number of different virtual machines that are configured with a native graphics driver. The GPU scheduler receives GPU commands from the different virtual machines, dynamically selects a scheduling policy, and schedules the GPU commands for processing by the GPU.

摘要： Examples may include a determining a checkpointing/delivery policy for primary and secondary virtual machines based on output-packet-similarities. The output-packet-similarities may be based on a comparison of time intervals via which content matched for packets outputted from the primary and secondary virtual machines. A checkpointing/delivery mode may then be selected based, at least in part, on the determined checkpointing/delivery policy.

摘要： Multiple operating systems are supported on a computing device by disk virtualization technologies that allow switching between a native operating system and a virtualized guest operating system without performing a format conversion of the native operating system image, which is stored in a partition of a physical data storage device. The disk virtualization technologies establish a virtual storage device in a manner that allows the guest operating system to directly access the partition of the physical storage device that contains the native operating system image.

摘要： Embodiments described herein relate generally to managing the power consumption of a virtual machine on a computing device. The computing device may include a virtual machine power management feature that is to detect when a virtual machine running on the computing device should be frozen. In response to this detection, the virtual machine may be frozen by reducing the processor cycles consumed by the virtual machine. This detection may be based on, for example, detection that the virtual machine is no longer running in the foreground or detection that the virtual machine is idle. The computing device may be a portable electronic device in which power consumption is an important consideration. Other embodiments may be described and/or claimed.

摘要： Apparatuses, methods and storage medium associated with live migration of virtual machines (VMs) from/to host computers with graphics virtualization are disclosed herein. In embodiments, an apparatus may include a virtual machine monitor (VMM) having a memory manager to manage accesses of system memory of the apparatus, including tracking of modified memory pages of the system memory. Additionally, the VMM may include a graphics command parser to analyze graphics commands issued to a graphics processor (GPU) of the apparatus to detect writes to the system memory caused by the graphics commands, and augment the tracking of modified memory pages. Further, the VMM may include a live migration function to live migrate a VM to another apparatus, including provision of current memory content of the VM, utilizing modified memory pages tracked by the memory manager, as augmented by the graphics command parser.

摘要： Embodiments of the invention enable dynamic level boosting of operations across virtualization layers to enable efficient nested virtualization. Embodiments of the invention execute a first virtual machine monitor (VMM) to virtualize system hardware. A nested virtualization environment is created by executing a plurality of upper level VMMs via virtual machines (VMs). These upper level VMMs are used to execute an upper level virtualization layer including an operating system (OS). During operation of the above described nested virtualization environment, a privileged instruction issued from an OS is trapped and emulated via the respective upper level VMM (i.e., the VMM that creates the VM for that OS). Embodiments of the invention enable the emulation of the privileged instruction via a lower level VMM. In some embodiments, the emulated instruction is executed via the first VMM with little to no involvement of any intermediate virtualization layers residing between the first and upper level VMMs.

摘要： Embodiments of graphics instruction instrumentor (“GII”) and a graphics profiler (“GP”) are described. The GII may facilitate profiling of execution of graphics instructions by one or more graphics processors. The GII may identify target graphics instructions for which execution profile information is desired. The GII may store instrumentation graphics instructions in a graphics instruction buffer. The instrumentation graphics instructions may facilitate the GP in collecting graphics profile information. For example, timestamp-storage instructions may be store timestamps before and after execution of the target graphics instructions. The GII also may store an interrupt-generation instruction to cause an interrupt to be sent to the GP so that the GP may begin collection of graphics profile data. The GII may store an event-wait instruction to pause the graphics processors until an event is received. Other embodiments may be described and claimed.

摘要： Embodiments of apparatus, computer-implemented methods, systems, and computer-readable media are described herein for a virtual machine monitor. The virtual machine monitor may be configured to determine whether to schedule a virtual central processing unit of one of a plurality of virtual machines on a first physical processing unit of a plurality of physical processing units. Each virtual machine may have one or more virtual central processing units. The determination may be based at least in part on whether a context of the virtual central processing unit suggests a desired cache hit rate on one or more cache units of the apparatus by the first physical processing unit when operating the virtual central processing unit.
