摘要： Provided is a method of controlling a virtual computer system in which a physical computer includes a plurality of physical CPUs that is switchable between a sleep state and a normal state, and a virtualization control unit divides the physical computer into a plurality of logical partitions to run a guest OS in each of the logical partitions and controls allocation of resources of the physical computer to the logical partitions, causes the virtualization control unit to: receive an operation instruction for operating the logical partitions; and if the operation instruction is for deleting a virtual CPU from one of the logical partitions, delete this virtual CPU from a table for managing virtual CPU-physical CPU allocation and put, if the deleting leaves no virtual CPUs allocated to one of the physical CPUs that has been allocated the deleted virtual CPU, this one of the physical CPUs into the sleep state.

摘要： Provided is a computer system in which an I/O card is shared among physical servers and logical servers. Servers are set in advance such that one I/O card is used exclusively by one physical or logical server, or shared among a plurality of servers. An I/O hub allocates a virtual MM I/O address unique to each physical or logical server to a physical MM I/O address associated with each I/O card. The I/O hub keeps allocation information indicating the relation between the allocated virtual MM I/O address, the physical MM I/O address, and a server identifier unique to each physical or logical server. When a request to access an I/O card is sent from a physical or logical server, the allocation information is referred to and a server identifier is extracted from the access request. The extracted server identifier is used to identify the physical or logical server that has made the access request.

摘要： Arbitration of IO accesses and band control based on the priority of virtual servers is enabled while curbing performance overhead during IO sharing among the virtual servers. A virtual machine system includes a CPU, a memory, a hypervisor that generates plural virtual servers, and an IO controller that controls an IO interface. The IO controller includes: a DMA receiving unit that receives DMA requests from the IO interface; a decoder that decodes received DMA requests and locates the corresponding virtual servers; a DMA monitoring counter that monitors DMA processing status for each of the virtual servers; a threshold register set in advance for each of the virtual servers; and a priority deciding unit that compares the DMA monitoring counter and the value of the threshold register, and based on processing priority obtained as a result of the comparison, decides the priority of processing of the received DMA requests.

摘要： When a subject of access of a transaction from an IO device is not any resource allocated to a logical partition to which the device having issued the transaction belongs, a report as an error is sent to a CPU, while the transaction is finished on the IO bus. To prevent a transaction between IO devices from gaining access to any resource in another logical partition, one access permission bit is provided for each combination of all the IO devices, and the access is permitted only when the bit has a predetermined value. A reset signal is provided by IO slot so that only an IO slot allocated to a specific logical partition can be reset without affecting any other logical partition. A transaction issued from an IO device in one logical partition is prevented from gaining access to a resource in another logical partition, while proper error handling can be performed.

摘要： When the entire system is split into plural partitions on chipsets connecting plural processors, IO hubs, and memory controllers, and an OS is operating on each of the partitions, the present invention prevents a failure in a partition from propagating to other partitions. Based on address information or issuer information included in a packet inputted to a chipset, a partition from which the packet was issued is identified, and an identified partition identifier is added to the packet. Based on the added partition identifier, a partition initializing part selectively deletes the packet issued from the partition in which a failure occurred, thereby preventing the influence of the failure in the failure-causing partition from propagating to other partitions.
