Virtual Machine-to-Image Affinity on a Physical Server

摘要

Techniques, systems, and articles of manufacture for improving virtual machine-to-image affinity on a physical server. A method includes identifying physical machines in a network as candidate source physical machines, wherein each candidate source physical machine stores a first virtual machine image and a set of additional virtual machine images, identifying physical machines in the network as candidate target physical machines, wherein each candidate target physical machine stores one of the additional virtual machine images, and selecting a virtual machine image from the set of additional virtual machine images and selecting a physical machine from the candidate target physical machines such that migrating the selected virtual machine image from a candidate source physical machine to the selected target physical machine results in a maximized image affinity per virtual machine in comparison to each image migration scenarios for the set of additional virtual machine images.

1. A method comprising:
identifying one or more physical machines in a network as a candidate source physical machine, wherein each candidate source physical machine stores a first virtual machine image and a set of one or more additional virtual machine images; identifying one or more physical machines in the network as a candidate target physical machine, wherein each candidate target physical machine stores one of the set of one or more additional virtual machine images; and selecting a virtual machine image from the set of one or more additional virtual machine images and selecting a physical machine from the one or more candidate target physical machines such that migrating the selected virtual machine image from a candidate source physical machine to the selected target physical machine results in a maximized image affinity per virtual machine in comparison to each image migration scenarios for the set of one or more additional virtual machine images; wherein at least one of the steps is carried out by a computer device.
