Abstract

Embodiments of the present invention provide a method, system and computer program product for collocating VMs based on memory sharing potential. In an embodiment of the invention, a VM co-location method has been claimed. The method includes selecting a VM from amongst different VMs for server colocation. The method additionally includes computing an individual shared memory factor for each of a set of the VMs with respect to the selected VM. The method yet further includes determining a VM amongst the VMs in the set associated with a highest computed shared memory factor. Finally, the method includes co-locating the determined VM with the selected VM in a single server.

First claim

We claim:

1. A virtual machine collocating system comprising:
a cluster of servers, each with at least one processor and memory;
a plurality of virtual machines (VM) executing in the cluster of servers;
a hypervisor executing in memory of one of the servers; and,
a VM collocate module coupled to the hypervisor, the module comprising program code enabled to select a VM from amongst the plurality of VMs for server colocation, to compute an individual shared memory factor for e…
