Abstract: A communication channel may be implemented from a host operating system (OS) to a guest OS of a virtual machine. The method may include receiving an instruction to create a communication channel between a guest OS of a virtual machine and host OS of a host computer system. The method may further include transmitting, to a virtual Universal Serial Bus (USB) hub executed by the host OS, a first request to create a virtual USB device on the virtual USB hub. The method may also include providing the virtual USB device to the guest OS and identifying an operation to be performed by the guest OS on the virtual USB device. The method may include providing, from the guest OS to the virtual USB hub of the host OS, a second request that includes the operation to be performed by the guest OS.

Abstract: Systems and methods for pre-fetching data based on memory usage patterns. An example method comprises: receiving a first memory access request identifying a first memory block; receiving a second memory access request identifying a second memory block; update a memory access tracking data structure by incrementing a sequence counter corresponding to a memory access sequence that references the first memory block and the second memory block; receive a third memory access request identifying a third memory block; identifying, based on the memory access tracking data structure, a sequence counter having a maximal value among sequence counters associated with memory access sequences that reference the third memory block; and pre-fetching a fourth memory block corresponding to the identified sequence counter.

Abstract: A method and computer program product for running a remote desktop application on a mobile device without audio interference from the other desktop applications, so the remote user applications runs as if it were a native mobile device application. A remote host desktop has a number of applications running simultaneously and producing sounds. A mobile device user selects one application and launches it on his mobile device. The selected application runs on a mobile device and the sounds produced by all other desktop applications are filtered out by special audio control driver implemented on the host system.
