    Abstract: Methods are provided for using a hardware module connectable to multiple computer systems, where the multiple computer systems are connectable to a server within a common network. The method includes: providing a network address of the server in persistent memory of the hardware security module; providing an encrypted secret entity in the persistent memory of the hardware security module; providing a private key in the persistent memory of the hardware security module; and based on the hardware security module being connectable to one of the computer systems, the method includes: establishing a secure connection between the hardware security module and the server; retrieving, via the secure connection, a wrapping key from the server and storing it in volatile memory of the hardware security module; and decrypting the encrypted secret entity with the wrapping key and storing the decrypted secret entity in the volatile memory of the hardware security module.

    Abstract: A method is provided for suspending and resuming virtual machines in a network in dependence of network activity. The method includes providing a virtual machine manager. The virtual machine manager monitors network traffic of the virtual machines on a network bridge in a network layer using data packet analysis to detect dedicated network protocol traffic. More particularly, the monitoring of network traffic of the virtual machines may include: logging network addresses of the virtual machines of the network; combining logged network addresses with information about suspending or resuming virtual machines based on filtering rules being provided for such combination; and sending information about the network addresses of active and suspended virtual machines for virtual network adapters assigned to the virtual machines to the virtual machine manager.
