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:
Methods, systems, and computer programs are provided for managing remote display performance. One method includes operations for receiving notifications of events identified by an operating system, and for receiving notifications of display updates destined to a remote display coupled to a remote client. The method includes an operation for correlating events and display updates to determine the transmittal priority for the updates, where the priority is associated with a criticality for presenting the display updates on the remote display. Further, a subset of the display updates are identified as unnecessary for transmission to the remote client based, at least in part, on the priority of the display updates. Additionally, the method includes an operation for performing at least one of: discarding the subset; consolidating the subset into a single display update for transmittal to the remote client; or limiting the frequency of transmission of the subset to the remote client.
Abstract:
In a computer-implemented method for providing management of a virtualization infrastructure, a query related to the virtualization infrastructure is received. A graph database of the virtualization infrastructure is accessed, the graph database including nodes associated with members of the virtualization infrastructure and edges associated with relationships of the members of the virtualization infrastructure, wherein the nodes and the relationships include types. An answer to the query is received from the graph database.
Abstract:
Methods, systems, and computer programs are provided for measuring the performance of display images received on a remote computer display. One method includes an operation for detecting calls from an application to an application programming interface (API), which is provided for rendering images on a display image, each call causing an update of the display image. Further, the method includes an operation for embedding data for measuring performance in display frames of the display image based on the detecting. The embedding results in modified displayed frames with respective data for measuring performance. The modified displayed frames are transmitted to a remote client, which results in received modified display frames having respective received data for measuring the performance. In addition, the method includes an operation for calculating the remote display quality for the given application based on the received modified display frames and the respective received data for measuring performance.
Abstract:
In one embodiment, a method displays images from a remote desktop of a desktop GUI on a client device. The method receives a plurality of image blocks for a frame update of an image of the desktop GUI being displayed on the client device. The remote desktop is being run on a host. The client device determines that one or more missing image blocks have not been received for the frame update and determines if the frame update should be performed without the one or more missing image blocks. If the frame update of the desktop GUI should be performed without the one or more missing image blocks, the client device performs the frame update of the desktop GUI using the plurality of image blocks without using the one or more missing image blocks.

Abstract:
In a computer-implemented method to facilitate administration of a virtualization infrastructure, operational conditions of members of the virtualization infrastructure are monitored, wherein the members of the virtualization infrastructure are mapped to a social network such that at least a portion of the members of the virtualization infrastructure are also members of the social network. A group of members of the virtualization infrastructure is created within the social network based at least in part on the operational conditions.
Abstract:
In a computer-implemented method to facilitate administration of a member of a network, performance of a member of a network is monitored by an agent, wherein members of the network are provided with access to a shared message stream such that the members of the network are able to monitor messages generated by other members of the network posted to the shared message stream. Responsive to the agent identifying a specific operational condition of the member, the shared message stream is monitored for a message related to the specific operational condition. Provided the shared message stream comprises a message related to the specific operational condition identified by the agent, an association of the message with an indication that the member identifies with the specific operational condition is established, wherein the agent is configured to establish the association.
Abstract:
Methods, systems, and computer programs are provided for managing remote display performance. One method includes an operation for determining pixel data for a group of macroblocks, each macroblock having a group of pixels. The macroblocks are for embedding in respective video frames of a video stream. The pixel data for each pixel in each macroblock is calculated with a formula based on the frame number of the respective video frame and on the location of the pixel within the macroblock. Farther, the method includes operations for embedding the macroblocks in the respective video frames, and for transmitting the video frames with the embedded macroblocks to a remote client. A performance metric for the transmitted video stream is calculated based on the macroblocks received at the remote client by comparing the received macroblocks to the expected macroblocks based on the formula.
Abstract:
One method for managing remote display performance includes operations for embedding pixel data in a file of an application executing on a server, and detecting an open window of a graphical user interface (GUI) associated with the application. The pixel data is used to create a pixel strip in the window, while the GUI is being displayed on a remote display of a remote client. Update information for the GUI being displayed on the remote display is transmitted from the server to the remote client, the update information corresponding to the change in the presentation of the open window on the server. Further, a change in a presentation of the open window is detected, and a pixel strip received at the remote display is identified. A performance metric for the remote display is calculated based on the received pixel strip when compared to the expected values for the pixel strip.
