Abstract: Apparatuses, methods and storage media associated with memory management in virtualized computing are disclosed herein. In embodiments, an apparatus may include a virtual machine manager to manage operations of a plurality of virtual machines, having a memory manager to manage allocation and de-allocation of physical memory to and from the plurality of virtual machines. Allocation and de-allocation may include de-allocation of unused and used physical memory allocated to a first of the plurality of virtual machines to recover physical memory for allocation to one or more other ones of the plurality of virtual machines, and re-allocation of physical memory for the previously de-allocated unused and used physical memory of the first virtual machine. Other embodiments may be disclosed or claimed.

Abstract: Embodiments described herein relate generally to managing the power consumption of a virtual machine on a computing device. The computing device may include a virtual machine power management feature that is to detect when a virtual machine running on the computing device should be frozen. In response to this detection, the virtual machine may be frozen by reducing the processor cycles consumed by the virtual machine. This detection may be based on, for example, detection that the virtual machine is no longer running in the foreground or detection that the virtual machine is idle. The computing device may be a portable electronic device in which power consumption is an important consideration. Other embodiments may be described and/or claimed.

Abstract: Apparatuses, methods, and computer-readable media for buffer provision application (“BFA”) are described. The BPA may facilitate display of a guest application executing in a host operating system (“host OS”). The host OS may provide for execution of a guest application, such as through use of an emulator configured to emulate a guest OS environment. The BFA may provide a drawing buffer for use by the guest application. The drawing buffer may be caused to be allocated within the host OS by the BFA. The BFA may then cause the allocated buffer to be provided to the guest application so that the guest application may draw frame data directly to the drawing buffer. The BFA may then facilitate access to the drawing buffer by the host OS when compositing drawing buffer data with other drawing data of the host OS. Other embodiments may be described and claimed.
