摘要： In order to provide an inexpensive way to share an I/O device loaded in an I/O drawer among a plurality of blades, in a server system including a plurality of servers, a PCI device, and a manager for initializing a PCI switch, the PCI device has a plurality of virtual functions (VFs). The PCI switch, which has VF allocation information which indicates association between the servers and the VFs, is configured to: receive a transaction from one of the servers or from the PCI device; when the received transaction is a transaction sent from the one of the servers, remove a server identifier with which a sender server is identified and transfer the received transaction to the PCI device; and when the received transaction is a transaction sent from the PCI device, attach a server identifier that is determined based on the VF allocation information.

摘要： The program attains compatibility of suppression of an overhead accompanying page exception handling in the case of operating a program whose amount of memory use is large on a virtual machine and suppression of the overhead accompanying page exception handling in the case of operating a first OS that has a function of making another OS run on a virtual machine. A VMM creates a shadow PT (Page Table) for prohibiting reading-writing of privileged memory that requires emulation of reading/writing by using a RSV-bit, and registers the shadow PT and the second PT that a second OS operating on the first OS has in an x86 compatible CPU equipped with page exception detecting function using two PT's. When a page exception occurs, the VMM refers to cause code of the page exception and, when a P field of the cause code is 0, determines immediately that emulation is unnecessary.

摘要： A method is provided which eliminates redundancy from the shadow PT operation performed by the virtual machine monitor (VMM) when the guest operating system running on a virtual machine updates a guest page table (PT) address. The VMM associates a plurality of shadow PTs with guest PTs and allocates their relation in memory. When it detects the update of a guest PT address, the VMM searches for a shadow PT corresponding to the updated guest PT. If the associated shadow PT exists, the VMM omits rewriting the shadow PT and registers the address of the shadow PT with the central processing unit (CPU). If the associated shadow PT does not exist, the VMM allocates a memory, creates a shadow PT, registers an address of the created shadow PT with the CPU, and records a relationship between the updated guest PT and the generated shadow PT.
摘要翻译：当在虚拟机上运行的客户操作系统更新访客页表（PT）地址时，提供一种消除虚拟机监视器（VMM）执行的阴影PT操作的冗余的方法。 VMM将多个阴影PT与客户PT相关联，并将其关系分配给内存。当检测到客户PT地址的更新时，VMM搜索与更新的客户PT相对应的影子PT。如果相关联的阴影PT存在，则VMM将省略重写阴影PT，并将阴影PT的地址与中央处理单元（CPU）注册。如果相关联的阴影PT不存在，则VMM分配存储器，创建阴影PT，向CPU注册创建的阴影PT的地址，并记录更新的客户PT与生成的阴影PT之间的关系。

摘要： There is a need for providing the Xeon CPU with a two-level VM that is independent of VMM types and prevents the throughput from degrading when the OS operates the privilege register. A machine is provided with a processor and memory. The machine includes a first virtual machine manager for managing a virtual machine, a second virtual machine for managing an operating system, first management information, and second management information. The processor is provided with a register and a shadowing function. The machine uses a virtualization method. The first virtual machine manager detects a call from the second virtual machine manager. The first virtual machine manager enables the shadowing function when it is determined that an instruction for enabling the shadowing function caused the call.

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： Provided is a failover method for a cluster system for realizing smooth failover of the guest OS's, even when there are many guest OS's, while reducing consumption of computer resources of a server. Smooth failover is realized by preventing competition during failover even when the number of guest OS's is increased. In a cluster configuration in which a slave/master cluster program is operated in a guest OS/host OS, the master cluster program (510) collects and transmits heartbeats of the slave cluster program, thereby realizing failure monitoring through the certain amount of heartbeats without depending on the number of guest OS's. Further, when the master cluster program monitors failures of the slave cluster program of its own computer to find a normal operation of the guest OS, the amount of communication through heartbeats is reduced by eliminating the necessity of communication to a standby system slave cluster program.
摘要翻译：提供了一种集群系统的故障转移方法，即使客户操作系统有很多客户操作系统也能实现客户操作系统的平滑故障切换，同时降低服务器计算机资源的消耗。即使客户操作系统的数量增加，也可以通过防止故障切换期间的竞争来实现平滑的故障切换。在从机/主机集群程序在客户OS /主机OS中运行的集群配置中，主集群程序（510）收集并发送从属集群程序的心跳，从而通过一定数量的心跳来实现故障监视，而没有取决于客户操作系统的数量。此外，当主集群程序监视其自己的计算机的从属集群程序的故障以查找客户OS的正常操作时，通过消除与备用系统从属集群程序的通信的必要性来减少通过心跳的通信量。
