Abstract: PURPOSE: A user application memory protecting method is provided to efficiently protect a user application memory without degradation of a virtualized computer system by suing a mechanism which minimizes execution overhead. CONSTITUTION: An executing context is moved from an executing application to a guest OS(Operating System). A hypervisor removes access right to a memory area of the application. The executing context is moved from the guest OS to the application. The hypervisor modifies a page table of a virtual memory area of the application.
Abstract translation: 目的：提供一种用户应用程序存储器保护方法，以有效地保护用户应用程序存储器，而不会因虚拟化计算机系统的恶化而使执行开销最小化的机制。 构成：执行上下文从执行的应用程序移动到客户操作系统（操作系统）。 管理程序删除对应用程序的内存区域的访问权限。 执行上下文从客户操作系统移动到应用程序。 管理程序修改应用程序的虚拟内存区域的页表。

Abstract: PURPOSE: Memory management system and method of virtual machine are provided to immediately deal with the used amount of the changeable memory by additionally allocating the memory to VM in which the memory is insufficient. CONSTITUTION: VM(Virtual Machines)(110) is used as a guest memory by allocating a predetermined part from a physical memory of a computer system. The VMM(Virtual Machine Manager)(120) manages VMs. If the lack of the guest memory of a first VM, the VMM allocates some of guest memories allocated to one or more of rest VMs.
Abstract translation: 目的：提供虚拟机的内存管理系统和方法，通过向存储器不足的VM另外分配内存来立即处理可更换存储器的使用量。 构成：通过从计算机系统的物理存储器分配预定部分，将VM（虚拟机）（110）用作来宾存储器。 VMM（虚拟机管理器）（120）管理虚拟机。 如果缺少第一个VM的guest虚拟机内存，则VMM会分配一些分配给一个或多个其他虚拟机的guest虚拟机内存。
