A system and method for providing quality of service during live migration includes determining one or more quality of service (QoS) specifications for one or more virtual machines (VMs) to be live migrated. Based on the one or more QoS specifications, a QoS is applied to a live migration of the one or more VMs by controlling; resources including at least one of live migration network characteristics and VM execution parameters.

Mechanisms are provided for virtualizing physical sensors and providing sensor data to a requestor using the virtualized physical sensors. The mechanisms obtain sensor data from a plurality of physical sensors and storing the sensor data in a virtual sensor storage system of the data processing system in at least one standardized format. A request from a requestor for a first type of sensor data is received which does not specify a particular physical sensor. A portion of the sensor data stored in the virtual sensor storage system is retrieved in response to receiving the request, the portion of sensor data corresponding to the type of sensor data requested in the request from the requestor. The retrieved portion of the sensor data is returned to the requestor in a format corresponding to a physical sensor configured to provide the requested type of sensor data.

Sensor virtualization through cloud storage and retrieval mechanisms

A method of saving power in a computing system having a plurality of dial in-line memory modules (DIMMs) and employing a suspend-to-RAM sleep mode includes, when entering suspend-to-RAM sleep mode, consolidating selected information into a subset of DIMMs, and turning off power to all other DIMMs. A DIMM power rail may be coupled to each of the DIMMs, the DIMM power rail being configured to selectively have power being supplied to respective DIMMs turned off in response to enable/disable logic signals.

Mechanisms are provided for determining the location of computing assets within an organization. These mechanisms determine first location information identifying a location of at least one first physical asset housing in a predetermined physical area of the organization relative to a predetermined coordinate system, and second location information identifying a location of at least one second physical asset housing within the at least one first asset housing. The mechanisms automatically determine third location information identifying a location of at least one computing asset within the at least one second physical asset housing. In addition, the mechanisms generate an asset location map data structure for the organization based on the first, second and third location information. The mechanisms also perform at least one management operation for managing resources of the organization, based on the asset location map data structure for the organization.

A mechanism is provided for performing secure recursive virtualization of a computer system. A portion of memory is allocated by a virtual machine monitor (VMM) or an operating system (OS) to a new domain. An initial program for the new domain is loaded into the portion of memory. Secure recursive virtualization firmware (SVF) in the data processing system is called to request that the new domain be generated. A determination is made as to whether the call is from a privileged domain or a non-privileged domain. Responsive to the request being from a privileged domain, all access to the new domain is removed from any other domain in the data processing system. Responsive to receiving an indication that the new domain has been generated, an execution of the initial program is scheduled.

Secure recursive virtualization

Mechanisms are provided for determining the physical location of a physical asset in a physical area. A plurality of physical assets are controlled to cause each physical asset to output a visual output pattern on visual output elements of the physical asset. An image of a target physical asset is captured that has the current state of the visual output elements. An identification of the target physical asset is determined based on the current state of the visual output elements. A physical location of the target physical asset is determined based on a physical location of the image capture device when the image was captured. Location data identifying the determined physical location of the target physical asset is stored in an asset database in association with configuration information for the physical asset.

Disclosed are a processor and processing method that provide non-hierarchical computer security enhancements for context states. The processor can comprise a context control unit that uses context identifier tags associated with corresponding contexts to control access by the contexts to context information (i.e., context states) contained in the processor's non-stackable and/or stackable registers. For example, in response to an access request, the context control unit can grant a specific context access to a register only when that register is tagged with a specific context identifier tag. If the register is tagged with another context identifier tag, the contents of the specific register are saved in a context save area of memory and the previous context states of the specific context are restored to the specific register before access can be granted. The context control unit can also provide such computer security enhancements while still facilitating authorized cross-context and/or cross-level communications.
