Abstract: A host-side overcommit value is set upon a physical node that implements virtual machines (VM Node). The overcommit value is determined by receiving a selected enablement template that includes a selected computing capacity and a selected overcommit value. A user-side normalization factor is determined that normalizes the selected computing capacity against a reference data handling system. A comparable computing capacity of the VM Node is determined. A host-side normalization factor is determined that normalizes the comparable computing capacity against the reference data handling system. The host-side overcommit value is determined from the selected overcommit value, the user-side normalization factor, and the host-side normalization factor. The host-side overcommit value may indicate the degree the comparable computing capacity is overcommitted to virtual machines deployed upon heterogeneous VM Nodes as normalized against the reference system.

Abstract: Systems, methods, and computer program products to perform an operation, by, responsive to a request specifying to transition a state of a virtual machine in a cloud computing environment from a first state to a second state, allocating one or more system resources to the virtual machine during the transition from the first state to the second state, and, upon completion of the transition, releasing a portion of the allocated one or more system resources to a pool of available resources, so that the virtual machine is left with a remaining portion of the allocated one or more resources sufficient for operation during the second state.

Abstract: A method, a system, and a computer program product for managing the resources of a virtual machine on a physical server are provided. The method includes receiving, at a management application, a request to increase a first virtual resource from an initial level to an increased level for a first virtual machine. The first virtual machine is provided by a first physical server in a computing environment. The method also includes determining whether a free virtual resource for the first physical server is sufficient for the request at the increased level. The method also includes increasing, in response to the free virtual resource being insufficient for the request, the first virtual resource.

Abstract: Methods for managing an address on a switching device, managing an address on a network switch, and screening addresses in a cloud computing environment are provided. One embodiment is directed towards a computer-implemented method for managing an address on a switching device that is communicatively coupled to a plurality of virtual machines. The method includes accessing an address pool that includes an assigned address for each virtual machine from the plurality of virtual machines. The method includes determining, on the switching device, a used address for the virtual machine from the plurality of virtual machines. The method includes determining whether the used address is matching the assigned address for each virtual machine.

Abstract: Techniques are disclosed for virtual machine trust isolation in an Infrastructure-as-a-Service (IaaS) cloud environment. More specifically, embodiments of the invention monitor levels of suspicious activity on a particular virtual machine using node agents embedded in each physical node. The node agents transmit activity data to a security and relocation engine. If a virtual machine's suspicious activity levels exceed defined suspicious activity thresholds, the security and relocation engine assigns that virtual machine to a different zone. The zones may have reduced connectivity and/or service levels. This enables administrators to more efficiently respond to security threats in the cloud environment.

Abstract: A mobile wireless device connects to a network of multiple wireless transceiver stations using a protocol in which a connection is established with a particular transceiver station. If the mobile device moves out of range of the original station, the connection is passed to another station, which then impersonates the original station, without dropping the connection. Preferably, the original station provides a virtual Media Access Control (MAC) address to identify itself when the connection is established, and this virtual MAC address is passed to any successor station. Preferably, the station monitors signal strength and automatically passes the connection by polling its neighbors upon determining that signal strength is getting weak.
