Abstract: A method automatically parameterizes bay controllers and/or protective devices of a switching arrangement. The method includes automatically detecting the topology of the switching arrangement on the basis of topology information, and automatically determining interlocking and/or enabling conditions for at least one device on the basis of the topology. Communication connections for the at least one device are automatically specified while taking into account the interlocking and/or enabling conditions determined for this device. The at least one device is parameterized with the interlocking and/or enabling conditions and the communication connections and the topology determined for this device, so that interlocking or enabling of a switching action in the at least one device is controllable during the operation of the switching arrangement.

Abstract: Virtual machines may be configured in a complex computing environment having dependencies among themselves and on the virtualization platform they operate on. The present disclosure formalizes these dependencies by defining a component framework that enables a deployer to know about the dependencies at deployment time and allow the platform to ensure that all required dependencies are satisfied at runtime. Disclosed is a set of Open Virtualization Format (OVF) sections that allow an OVF package to express dependencies to services using OVF meta-data. At deployment time, those OVF sections allow the platform to recognize and honor those dependencies, and at runtime provide the virtual machines with appropriate configuration meta-data.

Abstract: A disclosed example method to aggregate resources in a cloud involves receiving a request for a resource at a first tenant application programming interface provider of an internal cloud service. The example method involves using a virtualization platform application programming interface client of the internal cloud service to access the resource when the resource is an internal resource. When the resource is an external resource, a tenant application programming interface client of the internal cloud service is used to send a second request for the resource to a second tenant application programming interface provider of an external cloud service.

Abstract: In a specific embodiment, a secure two-way multi-message communication channel between a virtualization platform and a guest running on a virtual machine hosted on the virtualization platform is provided using the OVF environment channel. The OVF environment may be used to transmit communication parameters from the platform to the virtual machine during power-on. At runtime, a guest executing on the virtual machine may use the communication parameters to establish a secure two-way communication channel with the virtualization platform.
