Abstract: Exemplary methods, apparatuses, and systems include a client virtual machine processing a system call for a device driver to instruct a physical device to perform a function and transmitting the system call to an appliance virtual machine to execute the system call. The client virtual machine determines, in response to the system call, that an established connection with the appliance virtual machine has switched from a first protocol to a second protocol, the first and second protocols including a high-performance transmission protocol and Transmission Control Protocol and Internet Protocol (TCP/IP). The client virtual machine transmits the system call to the appliance virtual machine according to the second protocol. For example, the established connection may switch to the second protocol in response to the client virtual machine migrating to the first host device from a second host device.

Abstract: A method for measuring performance of virtual desktop services offered by a server including a processor is described. A first encoded watermark is embedded into user interface display generated by a virtual desktop when initiating an operation. The first encoded watermark includes pixels identifying the operation and indicating its initiation. A second encoded watermark is embedded into the user interface upon completion of the operation indicating completion of the operation. An action performance time is then computed and stored in a memory. Multiple performance times may be compiled from multiple operations of multiple virtual desktops to assess the performance of the system as a whole.

Abstract: Embodiments of a supplemental message display method and system are described. Supplemental messages to be displayed on the client display of a network client are defined and comprise content that is separate from content generated by any application currently executed on the network client. A virtual desktop view is served from a server computer to the network client. The virtualization layer defines a screen region on the virtual desktop view of the client display device through for the display of one or more of the supplemental messages. The virtualization layer controls the size, location, color, and transparency level of the defined screen region. The defined screen region is made persistent to ensure the continual display of the supplemental message. The supplemental message content is provided to the network client and interactive user input is received through the displayed message.

Abstract: In one embodiment, a client device configured to remotely access a desktop hosted by a server system determines an event related to a user input for a desktop operation directed to the desktop. The client device receives a plurality of updates to a desktop graphical user interface (GUI) from the desktop hosted by the server system. Then, the client device correlates the event to an update in the plurality of updates to the desktop GUI based on a rule in a set of rules correlating events to updates. A metric is monitored for the update and information measured for the metric is stored.

Abstract: A method for measuring performance of virtual desktop services offered by a server including a processor is described. A first encoded watermark is embedded into user interface display generated by a virtual desktop when initiating an operation. The first encoded watermark includes pixels identifying the operation and indicating its initiation. A second encoded watermark is embedded into the user interface upon completion of the operation indicating completion of the operation. An action performance time is then computed and stored in a memory. Multiple performance times may be compiled from multiple operations of multiple virtual desktops to assess the performance of the system as a whole.

Abstract: In one embodiment, a server system receives, from a client device configured to remotely access a desktop hosted by the server system, user input directed to the desktop. The server system further identifies a desktop operation to be performed in response to the user input, where the identifying is performed without relying on preconfigured information that indicates what the desktop operation should be, determines when the desktop operation has completed, and adds, upon completion of the desktop operation, one or more markers to the desktop. The server system then transmits an image of the desktop that includes the one or more markers to the client device, thereby signaling the completion of the desktop operation to the client device.
