摘要： In scheduling shared processing that has a higher priority than LPAR processing, giving precedence to physical CPUs running idle LPARs prevents prolonged hold-up of LPAR processing. In a system is comprised of multiple physical CPUs, multiple LPARs to which these physical CPUs are allocated and which execute programs under their guest OSes, and a management program managing these LPARs, a few additional units are introduced: a guest OS monitoring unit that can grasp the states of guest OSes running on these LPARs and a dispatcher unit that allocates one of these physical CPUs to shared processing requested by the management program, which has a higher priority than LPAR processing. When a request for shared processing arises, the dispatcher unit interrogates the guest OS monitoring unit and, based on the information obtained from it, gives priority of allocation to the physical CPU processing an idle LPAR.

摘要： In a processor capping method in a virtual machine system, a complement virtual machine is created having a possessive processor time equal to the difference of subtraction of a possessive processor time given to the processor capping enabled virtual machine from a possessive processor time of the whole physical computer; a processor time by which each virtual machine utilizes the physical processor per unit time is determined; schedule priorities of each virtual machine and of the complement virtual machine are determined on the basis of their possessive processor times and the determined utilization processor time as well; and the schedule priority of the processor capping enabled virtual machine is compared with that of the complement virtual machine corresponding to the processor capping enabled computer to decide whether the schedule for the physical processor of the virtual processor the processor capping enabled virtual machine has is permissible or prohibitive.

摘要翻译：在调度具有比LPAR处理优先级更高的共享处理的情况下，优先运行空闲LPAR的物理CPU可以防止LPAR处理的长时间保持。在一个系统中包括多个物理CPU，分配了这些物理CPU的多个LPAR以及在其客户操作系统下执行程序的多个LPAR，以及管理这些LPAR的管理程序，引入了几个附加单元：客户操作系统监视单元，掌握在这些LPAR上运行的客户操作系统的状态以及将这些物理CPU之一分配给管理程序所请求的共享处理的调度单元，其具有比LPAR处理更高的优先级。当发生共享处理的请求时，调度单元询问客户操作系统监视单元，并且根据从其获得的信息给处理空闲LPAR的物理CPU的分配优先级。

摘要： The network connection of a VM (target VM) that has been live-migrated from a first physical computer to a second physical computer is restored in a virtual computer system in which communication is performed using a certain type of information outside the jurisdiction of a virtualization mechanism. When receiving a packet from the VM, the first virtualization mechanism of the first physical computer extracts a certain type of information from the packet and registers the extracted certain type of information in a first management information unit. The first virtualization mechanism transmits the certain type of information in the first management information unit to the second virtualization mechanism of the second physical computer during live migration. The second virtualization mechanism registers the certain type of information in a second management information unit and transmits a certain type of packet including the certain type of information from at least one of one or more physical I/O devices of the second physical computer in order to restore the network connection of the target VM.

摘要： A hypervisor sets all physical areas in an allocation area, which is allocated to a virtual machine from within a physical memory and is configured from a plurality of physical areas, to a write protect mode. In a case where a physical processor identifies that the write-destination area from the virtual machine is in the write protect mode, the hypervisor manages the write-destination area as an updated area, and cancels the write protect mode of the write-destination area. At a certain point in time, the hypervisor copies data inside the updated physical area from within the allocation area to a storage area (a copy area) that differs from the allocation area. In a case where a prescribed failure is detected in the physical area, the hypervisor restores data from the copy area.
