Abstract
A host controller migrates live virtual machines from one host to another host to balance the load in the host cluster. In one embodiment, the host controller identifies an overloaded host from the host cluster. The host controller selects a virtual machine from the existing virtual machines that run on the overloaded host based on a percentage value associated with the virtual machine. The percentage value represents CPU usage incurred by the virtual machine on the host. In one embodiment, the selected virtual machine is one that incurs the least amount of load on the host. The host controller then selects a target host from the host cluster as a destination for migrating the selected virtual machine.
