Abstract: Systems and methods are described for replacing image data from a virtual machine with local image data, such as for a video application. In some aspects, a method for replacing image data in a video application may include obtaining first image data from a camera connected to the user device and transmitting the first image data to a virtual machine that executes the video application. The user device may receive a video application image from the virtual machine that includes an indication that identifies the first image data. The user device may identify the first image data in the video application image based on the indication and replace it with second image data obtained from the camera device to produce a modified video application image. The client device may render the modified video application image in a virtual computing environment displayed on the user device.

Abstract: Methods and system for power management of computing resources supporting one or more virtual machines involves grouping the plurality of virtual machines into a plurality of groups. The grouping can comprise assigning each of the plurality of virtual machines to one or more of the plurality of groups based on virtual machine functionality. For each group, a further determination is made as to whether the level of activity is indicative of an idle state. Upon determining that the level of activity associated with a group is indicative of an idle state, that group of virtual machines is instructed to enter a low power mode.
