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.
