摘要： 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 embodiment provides a computer program product including computer usable program code for performing a method that 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.

摘要： A computer-implemented method comprises obtaining a cache hit ratio for each of a plurality of virtual machines, and identifying, from among the plurality of virtual machines, a first virtual machine having a cache hit ratio that is less than a threshold ratio. The identified first virtual machine is then migrated from the first physical server having a first cache size to a second physical server having a second cache size that is greater than the first cache size. Optionally, a virtual machine having a cache hit ratio that is less than a threshold ratio is identified on a class-specific basis, such as for L1 cache, L2 cache and L3 cache.

摘要： A computer implemented method is provided, including monitoring the utilization of resources available within a compute node, wherein the resources include an input/output capacity, a processor capacity, and a memory capacity. The method further comprises allocating virtual machines to the compute node to maximize use of a first one of the resources; and then allocating an additional virtual machine to the compute node to increase the utilization of the resources other than the first one of the resources without over-allocating the first one of the resources. In a web server, the input/output capacity may be the resource to be maximized. However, unused memory capacity and/or processor capacity of the compute node may be used more effectively by identifying an additional virtual machine that is memory intensive or processor intensive to be allocated or migrated to the compute node. The additional virtual machine(s) may be identified in new workload requests or from analysis of virtual machines running on other compute nodes accessible over the network.

摘要： A computer implemented method is provided, including monitoring network traffic among virtual machines allocated to a plurality of compute nodes on a network, and identifying first and second virtual machines having inter-virtual machine communication over the network in an amount that is greater than a threshold amount of the network traffic. The method further comprises migrating at least one of the first and second virtual machines so that the first and second virtual machines are allocated to the same compute node and the inter-virtual machine communication between the first and second virtual machines is no longer directed over the network. In one embodiment, each compute node is coupled to an Ethernet link of a network switch, and data is obtained from a management information database of the network switch to determine the amount of network bandwidth that is being utilized for communication between the first and second virtual machines.
