摘要： Embodiments of apparatus, computer-implemented methods, systems, and computer-readable media are described herein for a virtual machine monitor. The virtual machine monitor may be configured to determine whether to schedule a virtual central processing unit of one of a plurality of virtual machines on a first physical processing unit of a plurality of physical processing units. Each virtual machine may have one or more virtual central processing units. The determination may be based at least in part on whether a context of the virtual central processing unit suggests a desired cache hit rate on one or more cache units of the apparatus by the first physical processing unit when operating the virtual central processing unit.

摘要： Various embodiments are generally directed to virtualized systems. A first guest memory page may be identified based at least in part on a number of accesses to a page table entry for the first guest memory page in a page table by an application executing in a virtual machine (VM) on the processor, the first guest memory page corresponding to a first byte-addressable memory. The execution of the VM and the application on the processor may be paused. The first guest memory page may be migrated to a target memory page in a second byte-addressable memory, the target memory page comprising one of a target host memory page and a target guest memory page, the second byte-addressable memory having an access speed faster than an access speed of the first byte-addressable memory.

摘要： Apparatuses, methods and storage medium associated with in-vehicle computing, are disclosed herein. An in-vehicle system computing platform having a hypervisor to host one or more virtual machines (VMs) includes a memory shrink manager, and a memory snapshot manager. The memory shrink manager is configured to orchestrate shrinking a memory footprint of one of the one or more VMs for a suspend process invoked in response to the computing platform being powered off. The memory snapshot manager is configured to save the shrunken memory footprint of the one VM to the persistent storage during the suspend process, and to reload a subset of the saved shrunken memory footprint during a resume process to resume the one VM from suspension to the persistent storage. The resume process is invoked in response to the computing platform being powered on, cold booted.

摘要： A host machine includes a guest machine, a device emulator, and a hypervisor communicably coupled to the guest machine and the device emulator. The guest machine executes a non-real time thread that causes a non-real time I/O emulation by the device emulator. Responsive to receipt of a real time thread by the guest machine, the hypervisor determines whether the non-real time I/O emulation is abortable or non-abortable. If abortable, the hypervisor aborts the non-real time thread and causes the guest machine to execute the real time thread. Upon completing the execution of the real time thread, the hypervisor causes the guest machine to revert to a non-real time context based on a previous system snapshot. Upon establishing the non-real time context, the hypervisor causes the guest machine to execute the previously aborted non-real time thread.
