Abstract: A method for shutting down a virtual system including several virtual machines hosted by one or more physical servers includes the steps of: receiving a shutdown command for the virtual system or detecting an event that triggers a process for shutting down of the virtual system; sending a request for data about dependencies in the virtual system; retrieving the requested data; generating a sequence of shutdown actions depending on the retrieved requested data, the sequence including a shutting down of all applications executed by the virtual machines, the shutting down of all virtual machines, and then the shutting down of all virtual machine managers; and executing shutdown actions in the generated sequence in order to shut down the virtual system.

Abstract: A plug adapter configured for application with a system for automatically deducing the electrical cabling between electrical devices includes: a plug configured to plug into in a socket of an electrical device; a socket configured to plug into a plug of an electrical cable; a light receiver positioned to receive light emitted by an optical fiber ending in the plug of the electrical cable; and an electronic unit configured to control the light receiver and/or the light emitter and including an interface configured to communicate with a cabling management system of the system configured to automatically deduce the electrical cabling between electrical devices in order to receive control signals for the light emitter and to transmit detection signals from the light receiver.

Abstract: A method of managing a system having a multitude of power sources and power loads, configured for execution in a computing device, the computing device being assigned to the system; and system having a multitude of power sources and power loads, wherein such a managing method is applied to the system.
