Abstract

A host system executing multiple virtual machines that is associated with multiple storage domains may be identified. Storage domain data may be received that includes utilization of each of the multiple storage domains by the multiple virtual machines. It may be determined that the utilization of a first storage domain of the multiple storage domains by the virtual machines satisfies a threshold utilization. In response to determining that the utilization of the first storage domain satisfies the threshold utilization, a second storage domain may be identified in view of a storage domain rank. An instruction may be provided to cause a storage migration of a virtual machine from the first storage domain to the identified second storage domain.
