Abstract: Eine virtuelle Maschine soll migriert werden. Um der virtuellen Maschine zu ermöglichen, eine Peripheriefunktion ohne lange Unterbrechung zu verwenden, wird eine Migrationsunterstützungseinheit (1705) bereitgestellt, wobei die Migrationsunterstützungseinheit (1705) dazu eingerichtet ist, eine Quellschreibanforderung zu empfangen, die durch eine Peripheriefunktion erzeugt worden ist, und eine Zielschreibanforderung zu erzeugen, die dieselben Schreibdaten aufweist wie die Quellschreibanforderung und an den Zielspeicherbereich der virtuellen Maschine gerichtet ist.

Abstract: Fast error reporting is provided in networks that have an architected delayed error reporting capability. Errors are detected and reported without having to wait for a timeout period to expire. Further, failures of other components caused by the delay are avoided, since the delay is bypassed.

Abstract: A virtual machine is to be migrated. In order to enable the virtual machine to use a peripheral function without a long interruption, a migration assistance unit (1705) is provided, wherein migration assistance unit (1705) is adapted to receive a source write request generated by a peripheral function, and to generate a destination write request comprising the same write data as said source write request and directed to said destination memory area of said virtual machine. The peripheral function may be blocked while the memory data is transferred, and the source virtual machine is paused when nearly all memory data is transferred to the destination. Further write requests are exclusively saved in the destination memory, which may be on the same or different computers.

Abstract: Processing, such as debug and/or recovery processing, within a communications environment is facilitated. Responsive to detecting an event, a stop signal is propagated through a communications network of the communications environment, and each network element that receives the stop signal, transmits the signal to its neighbors (if any), and then performs an action depending on its specific programming. The action can be to take no action, perform a debugging action or perform a recovery action. The elements that receive the signal and perform the same action as other elements form a coordinated network providing a coordinated result.
