Abstract: PROBLEM TO BE SOLVED: To efficiently migrate a virtual computer from a logical partition to another logical partition in the same computer or from a real computer to another real computer. SOLUTION: Before migration, a first virtual computer has an operating system and an application in a first exclusive memory dedicated to the first virtual computer; a communication queue of the first virtual computer is resident in a shared memory shared by first and second computers or first and second LPAR. The operating system and the application are copied from the first exclusive memory to the shared memory and thereafter copied form the shared memory to a second exclusive memory dedicated to the first virtual computer in the second computer or the second LPAR. The first virtual computer is resumed in the second computer or the second LPAR. COPYRIGHT: (C)2006,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a system for dispatching work items within a virtual computer operating system; a recording medium; and a method. SOLUTION: A first virtual computer allocates a first work item to a first work queue and a second work item to a second work queue. The first virtual computer schedules the work items coming from the first work queue for execution by the first virtual computer. A second virtual computer allocates a third work item to the first work queue and a fourth work item to the second work queue. A second virtual computer schedules the work items coming form the second work queue for execution by the second virtual computer. The first virtual computer cannot schedule the work items coming from the second work queue and the second virtual computer cannot schedule the work items coming from the first work queue. A shared work queue within a shared memory is also disclosed. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide a technique for integrally managing locks provided by a plurality of virtual computers to access shared data protected by the locks. SOLUTION: A first and a second virtual computer and a memory shared by the first and second virtual computers are defined. A lock structure is defined within the shared memory. The lock structure is capable of listing the holder of the lock about the shared data in the shared memory. The first virtual computer gains the lock about the shared data when it is usable through the operation of the lock structure. After gaining the lock, the first virtual computer accesses the shared data. The lock structure and the shared data can be directly accessed by the first virtual computer. The second virtual computer gains the lock about the shared data when it is usable through the operation of the lock structure. After gaining the lock the second virtual computer accesses the shared data. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: Von einem Computer durchgeführtes Verfahren, das aufweist:Ausführen eines ersten Hypervisors durch eine Verarbeitungseinheit über eine logische Partition;Ausführen eines zweiten Hypervisors durch die Verarbeitungseinheit über die logische Partition;Empfangen einer Anforderung für die Verwaltung eines virtuellen Servers an dem ersten Hypervisor;Auswerten der Anforderung, um Ressourcen zu ermitteln, die notwendig sind, um den virtuellen Server zu verwalten; undAuswählen des ersten Hypervisors oder aber des zweiten Hypervisors, um die Anforderung durchzuführen auf der Grundlage einer Auslastungsanalyse des ersten und des zweiten Hypervisors, wobei die jeweilige Auslastung des ersten Hypervisors und des zweiten Hypervisors überwacht wird und Ressourcen zwischen dem ersten Hypervisor und dem zweiten Hypervisor dynamisch zugeteilt werden, um der jeweiligen Auslastung Rechnung zu tragen,wobei ein Zugriff auf Hardware-Ressourcen durch den ersten und zweiten Hypervisor über die logische Partition erfolgt, wobei die logische Partition zumindest eine Teilmenge der Hardware-Ressourcen, die auf einem Computersystem vorhanden sind, darstellt, welche als ein gesonderter Computer virtualisiert wird, der von dem ersten und dem zweiten Hypervisor gemeinsam genutzt wird.

Abstract: Embodiments relate to a method for encapsulating a virtual server in a hypervisor subpartition of a single logical partition to provide additional hardware support and advanced virtualization functions. An aspect includes running a first hypervisor and one or more additional hypervisors over a single logical partition. A request to manage a virtual server is received at the first hypervisor. The request is then analyzed to determine what resources are necessary to manage the virtual server. Based on the analyzed request, one of the first hypervisor or the one or more additional hypervisors is selected to complete the request.
