PowerVM has NVRAM that is associated with each VM on the system. The NVRAM holds information about the VM such as which device is the boot device. PowerVM produces an event when the NVRAM for a VM is changed. The NVRAM should be set on the VM during operations like cold migration, resize to a different host and evacuation when the VM is newly created on the destination host from an existing VM on the source host. This change set introduces the concept of an NVRAM store and an NVRAM manager. The compute driver listens for the PowerVM NVRAM change events and stores the NVRAM in the configured store. A Swift store for the NVRAM is implemented. Future change sets will utilize the NVRAM from the store on VM operations and manage its life cycle. This change set does include storing the NVRAM during migrate/resize and was included to facilitate live testing. Change-Id: I59be9946794f53fdcae5515cc818d4fe967986d0
