摘要:
A system includes a network, a number of server computing devices, and a management server computing device. Each server computing device has a virtual host computer program running thereon to support one or more virtual machine computer programs. Each virtual machine computer program is able to execute an instance of an operating system on which application computer programs are executable. The management server computing device monitors the server computing devices, and causes the virtual machine computer programs supported by the virtual host computer program of a first server computing device to dynamically migrate to the virtual host computer program of a second server computing device, upon one or more conditions being satisfied. The conditions may include the first server being predicted as failure prone, the first sever consuming power less than a threshold, and the first server having resource utilization less than a threshold.

Permitting utilization of computer system resources in accordance with the licensing thereof is disclosed. A method includes conducting an inventory of the resources of a computer system. The method determines which of the resources of the computer system are licensed for current usage, and permits utilization of these resources. Other resources of the computer system that are not licensed for usage are prevented from being used. The method may include determining which resources are licensed for usage with metering. The method permits the utilization of such resources, and tracks utilization availability of these resources. The method may further include determining which resources are licensed for periodic usage. Once the method receives indication to allow the periodic usage of these resources, the method permits their utilization, and tracks their utilization availability as needed. Preferably, the method performs its functionality without rebooting or restarting the computer system.

Duration sensitive scheduling in a computing environment, the computing environment including a computer configured to support a virtual machine, including: identifying, by a duration sensitive scheduler, a processing job to be executed by the virtual machine, wherein the virtual machine includes an entitlement specification that identifies physical resources of the computer that are designated for exclusive use by the virtual machine; determining, by the duration sensitive scheduler, a duration required to complete the processing job; identifying, by the duration sensitive scheduler, a time slot at which the physical resources of the computer that are identified in the entitlement specification are available for use by the virtual machine; scheduling, by the duration sensitive scheduler, the processing job for execution on the virtual machine during the time slot at which the physical resources of the computer that are identified in the entitlement specification are available for use by the virtual machine.
摘要:
Virtual machines are managed on the basis of data obtained from a management information database of a network switch having a plurality of Ethernet links coupled to compute nodes running a plurality of virtual machines. A management entity, such as a provisioning manager, determines the amount of network bandwidth being utilized through each of the Ethernet links. Accordingly, an additional virtual machine may be provisioned to the compute node that is coupled to an Ethernet link identified as having the greatest amount of unutilized network bandwidth.

Virtual machines having a high amount of identical memory pages are grouped under a common hypervisor to enable greater memory savings as the result of transparent page sharing. One method comprises analyzing the software image content of a plurality of virtual machines running on a plurality of hypervisors in a common migration domain, identifying two or more of the virtual machines having greater than a threshold amount of common memory pages, placing the two or more virtual machines under a common hypervisor, and sharing the common memory pages among the two or more virtual machines. Optionally, the identifying of two or more of the virtual machines may include identifying two or more of the virtual machines having the same software image content classifications; thereby, identifying images with a greater affinity for common memory pages.
