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: The invention relates to a method and system for managing virtual network ports on a physical server (10) to provide a virtual server (20) access to a group of storage resources (110) through a network (100) and comprises the steps: generating a storage access group (SAG) (60) representing a group of storage resources (110); executing a hypervisor (14) on the physical server (10); generating a virtual server (20) on said hypervisor (14); for the virtual server (20) activating access to said network (100). A management console (70) creates and manages the storage access group (60) providing access to the group of storage resources (110) for the virtual server (20) the physical servers (10, 12). The management console comprises a virtual server management facility (72) and a SAG facility (74). The virtual server management facility (72) manages virtual server definitions and activates, deactivates, migrates virtual servers (20, 22). The SAG facility (74) provides management of virtual network port descriptions (60), administration of network port names (WWPN1, WWPN2) and creates, activates and deactivates virtual network ports (40). The SAG represents a group of storage resources, virtual servers requiring access to the storage resources and network ports required to access the storage resources.

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.
