摘要： A mechanism is described for mitigating the effects of such a DoS attack by detecting a multiple TDR situation within a short duration, identifying the errant virtual machines, and suspending all rendering ability for that virtual machine or set of virtual machines. While the disclosed embodiments are described in the context of virtual machines, the principles may be extended to the general problem of DoS attacks due to TDRs and bugchecks on any physical machine that includes a GPU. For example, DoS attacks can be generated from web sites directly using GPU rendering.
摘要翻译：描述了一种机制，用于通过在短时间内检测多个TDR情况来减轻这种DoS攻击的影响，识别错误的虚拟机，并暂停对该虚拟机或一组虚拟机的所有渲染能力。虽然所公开的实施例在虚拟机的上下文中被描述，但是这些原理可以被扩展到由于在包括GPU的任何物理机器上的TDR和错误检查引起的DoS攻击的一般问题。例如，可以直接使用GPU渲染从网站生成DoS攻击。

摘要： A mechanism is provided for making information about the virtual disk image file and/or its associated virtual image configuration file more readily available to a user. The virtual disk image file format is expanded to include fields in which information about the data in the file can be stored. Extensible information on file content, compatible HW configurations, compatible host OSes, timeout status, DRM status, patch state, and network topology, tag data for indexing, configuration files, saved state files, operation history data, and the like is stored in a location within a virtual disk image file that can be read without executing the virtual machine. This information can then be used to search the contents of the virtual disk image, to enforce usage policies, to provide extensibility for vendors, and the like.

摘要： A computer system and method for communicating in a virtual environment. The computer system may include a first partition and a virtual service client implemented at a first position in the first partition. The computer system may also include a second partition, and a virtual service provider implemented at a second position in the second partition. The first partition and the second partition may be in operative communication via the virtual service client and the virtual service provider. The first position and the second position may enable the virtual service client and the virtual service provider to reduce processing overhead associated with communicating in the virtual environment by eliminating a processing step, a buffer copy, a software interrupt, and/or a context switch.

摘要： In exemplary embodiments, device capabilities, i.e., functions performed in a hardware device, can be selectively enabled/disabled in a virtual machine by modifying configuration information for a hardware device emulator. For example, the configuration information can be changed in order to cause a guest operating system to load a specific device driver that enables/disables select hardware capabilities in a virtual machine. Other techniques are described in the claims, detailed description, and drawings.

摘要： A method of agreeing on the utilization of at least one computer resource between two virtual machines includes sending a first resource request by a first virtual machine to a second virtual machine having computer resources to allocate to the first virtual machine. The second virtual machine responds by sending at least one available resource for use by the first virtual machine. The first virtual machine can select from the at least one available resource. Both the first and second virtual machines can then execute on the agreed resource utilization by the first virtual machine and begin using the resource. When conditions change, either the first virtual machine or the second virtual machine can request a renegotiation of the agreement to use computer resources.
摘要翻译：一种同意在两个虚拟机之间使用至少一个计算机资源的方法包括：将具有计算机资源的第一虚拟机的第一资源请求发送给具有分配给第一虚拟机的计算机资源的第二虚拟机。第二虚拟机通过发送至少一个可用资源来响应，以供第一虚拟机使用。第一个虚拟机可以从至少一个可用资源中进行选择。然后，第一和第二虚拟机都可以由第一虚拟机在商定的资源利用率上执行，并开始使用资源。当条件改变时，第一个虚拟机或第二个虚拟机可以请求重新协商协议以使用计算机资源。

摘要： Methods, systems, and computer readable media are disclosed for creating a multi-port client server connection in a remote desktop environment. In an embodiment, the multi-client server connection can decouple client-server connection and client-server input from graphics delivery from the server to the client. Such embodiment provides higher server performance and enables dynamic server resource management. The multi-client server connection can be implemented in a virtual environment or between physical machines where one set of physical machines receives the graphics requests from the client and another set of physical machines generates and transmits display data to the client.

摘要： A computing device has a hardware device employed to provide a hardware service to the computing device and a plurality of virtual machines including a host virtual machine (VM-H) to which the hardware device is assigned, and a client virtual machine (VM-C) that can consume the hardware service by way of the VM-H. The VM-C includes an emulating stack and an enlightened stack. The emulating stack interfaces an application requesting the hardware service with a trap in a virtualization layer of the computing device which re-directs the request to the VM-H. The enlightened stack interfaces the application with the VM-H and bypasses the virtualization layer. The emulating stack includes a shunt driver that shunts to the enlightened stack each request from the application directed to the emulating stack.
