摘要： To determine, when a virtual machine is executed by an arbitrary machine, whether the virtual machine can access computer resources required for the virtual machine, provided is a method of checking a possibility of executing a virtual machine including a first physical computer for executing a first virtual machine and a second physical computer capable of executing a virtual machine. The method includes the steps of: acquiring information on first logical resources; acquiring setting information set to a adaptor of the first physical computer so that the first virtual machine accesses the first logical resources; listing second logical resources accessible when the first virtual machine is executed by the second physical computer by setting the setting information to a adaptor of the second physical computer; and determining whether the first virtual machine can be executed by the second physical computer by comparing the first and second logical resources.

摘要： A virtualization mechanism in a first computer of the plurality of computers generates at least one virtual computer on the first computer. The virtualization mechanism in the first computer executes at least one of a first judgment and a second judgment when a request for activating a first virtual computer of the at least one virtual computer is received, the first judgment being for judging whether or not the activation of the first virtual computer is prohibited based on first information stored in a memory of the virtualization mechanism, and the second judgment being for judging whether or not an identifier included in a logic I/O adapter device assigned to the first virtual computer is invalid based on second information stored in the memory of the virtualization mechanism. The activation of the first virtual computer is permitted or prohibited based on the executed judgment.

摘要： Allocation of virtual disk volumes of a size designated by the computer manager to a virtual computer and accessibility from the virtual computer to the virtual disk volumes without requiring intervention by a hypervisor are to be achieved. In a computer, at least one virtual computer to be in execution on the computer, and a computer system in which the virtual computer has volumes for holding data, a virtualization mechanism has a virtual volume allocating unit and a virtual volume information supplying unit, and the virtual computer has a virtual volume driver for converting positional information on virtual volumes. Additionally, the virtualization mechanism holds the virtual volume information together with defining information for the virtual computer to which the virtual volumes have been allocated.

摘要： Switching of the allocation of a device to a guest OS is implemented through transmission of a virtual suspension interrupt to a guest OS in a VMM; a power control notification process module that causes the guest OS to start a return process from a suspended state; a guest power process module that traps a suspension process of the guest OS; an I/O configuration change process module that updates a logical device definition of the VMM in the suspended state of the guest OS; a guest I/O emulation process module that emulates an I/O instruction that is issued by an I/O reconfiguration process module and that is executed when the guest OS has returned from the suspended state, thereby to provide a new logical device configuration to the guest OS.

摘要： A hypervisor is operated while an I/O device is not controlled by the hypervisor performs a process operation. A result of the process of the I/O device which is being concurrently operated is recorded to be capable of being reflected to the operation of the hypervisor. Therefore, a hypervisor which assigns a computer including an I/O control device controlling an I/O device, a main storage device, and a CPU as resources to each of one or more logical partitions (LPAR) and performs control, and a logging circuit recording data transmission from the I/O device to the main storage device, which is uncontrolled by the hypervisor, in response to an instruction from the hypervisor, are provided. It is possible to shorten a halt time period of an LPAR.

摘要： In a cluster that is composed of two computer nodes and has no common storage, mutual aliveness is monitored over networks. However, this is insufficient because a party node may be wrongly determined as inactive. If failover is performed according to wrong determination, the counterpart may be restored to a normal condition after the failover, so that both the two computers may operate as master. The two nodes to constitute the cluster and other computers to communicate with the cluster are connected by switches that can disable ports to which the computers are connected. A network control program that controls the switches changes the legality of use of ports to which the nodes are connected, synchronously with node failover.

摘要： A method of rebooting an operating system including a plurality of load modules in a single computer. One load module which is to be operated during rebooting of the operating system is held in a memory, while establishing a state capable of accepting interrupt to be processed by the one load module. All the other load modules are loaded in a memory of the computer. Processing of the interrupt can be executed by the one load module even during rebooting of the operating system.

摘要： A computer system of a multi-operation-system (multi-OS) has a main memory having a memory area for a first OS and a memory area for a second OS, both the areas being independent from each other, and a plurality of I/O devices divisionally allocated to the first OS and the second OS. The first OS is loaded in the first OS memory area, and thereafter when the first OS is operated, the second OS is loaded in the second OS memory area and initialized. When the first OS is operated, the first OS hardware resources and the second OS hardware resources are registered by the first OS. Thereafter when the first OS is operated, the first OS inhibits the registration of an interrupt number already allocated to the second OS I/O device. In response to an interrupt request from a second OS I/O device, the second OS starts operating.
