摘要： Virtual machine guest migration overcommit is supported by providing a virtual machine with an unschedulable resource that is not available for system scheduling. The unschedulable resource may, but need not, be provided in the form of a memory buffer, or one or more network resources, or one or more resources that are accessible from a network. The unschedulable resource is utilized in one or more domains to temporarily conceal one or more user environments that do not fit into a set of currently available resources, such that the one or more temporarily concealed user environments are not terminated or paged out.

摘要： A continuously operating system is provided and includes a processor and a computer readable medium to which the processor is operatively coupled, the computer readable medium having executable instructions stored thereon which, when executed, cause the processor to continuously load an operating system and to simultaneously operate as at least first and second mechanisms. The first mechanism loads a new module, which is a new version of an in-memory module of the operating system, into the operating system, and the second mechanism isolates and interrupts current access to the in-memory module such that subsequent access is to the new module.

摘要： A system and computer program product for migrating contents of a memory on a virtual machine. The system includes a source virtual machine executing on a host system, the source virtual machine including a memory. The system also includes a hypervisor executing on the host system. The hypervisor is in communication with the source virtual machine and includes instructions. The instructions facilitate establishing communication from the source virtual machine to a target virtual machine, the source virtual machine including a memory. The contents of the memory on the source virtual machine are transmitted to the target virtual machine. The contents of the memory on the source virtual machine include a plurality of pages. It is determined if all or a subset of the pages have been modified on the source virtual machine subsequent to being transmitted to the target virtual machine. If it is determined that all or a subset of the pages have been modified, then the modified pages, including a page location and page content for each of the modified pages, are transmitted to the target virtual machine. The determining and transmitting the modified pages continues until the number of remaining pages that have been modified is less than a threshold. The virtual machine is then paused the remaining pages are transmitted to the target virtual machine.

摘要： A computing system is provided and includes recording media relative to which input/output (I/O) operations are executable, and a processor, disposed in signal communication with the recording media, which is configured to execute the I/O operations and to evaluate power requirements associated with executions of the I/O operations relative to each individual recording medium. The processor includes a computer-readable medium having a set of instructions stored thereon, which, when executed, cause the processor to schedule the executions of the I/O operations relative to each individual recording medium or to refuse the executions of the I/O operations in accordance with the evaluated power requirements.
