    • 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.

    • 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 a page exception detecting function using two PT's. When a page exception occurs, the VMM refers to a cause code of the page exception and, when a P field of the cause code is 0, determines immediately that emulation is unnecessary.

    • 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.
    • 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。
