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： When the number of logical CPUs increases as the number of LPARs increases, a physical CPU amount which a hypervisor uses will increase and thus the physical CPU resource cannot be effectively utilized. Grouping of LPARs and physical CPUs is performed and a logical CPU to which a physical CPU is allocated is selected from logical CPUs of an LPAR within a group.

摘要： A virtual machine control method and a virtual machine system are disclosed. In the case where a guest program can be operated in a plurality of address translation modes and the same guest virtual address is translated into different host real addresses in each address translation mode, the illegal access to a host real address by illegal address translation by double registration in the same page table is avoided, and the address translation mechanism is efficiently operated. A plurality of host page tables are prepared in the main storage, and one of the host page tables is selected with the change in address translation mode of the guest program. The bottom address of the selected host page table is set in the host page table register thereby to switch the host page table.
摘要翻译：公开了虚拟机控制方法和虚拟机系统。在客户程序可以以多种地址转换模式操作并且在每个地址转换模式中将相同的客户虚拟地址转换为不同的主机实地址的情况下，通过双重地址转换的非法地址转换非法访问主机实地址避免了在同一页表中的注册，并且有效地操作了地址转换机制。在主存储器中准备多个主机页表，并且通过访客程序的地址转换模式的改变来选择一个主页面表。所选主机页表的底部地址在主页表寄存器中设置，从而切换主页表。

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。
