In order to alleviate I / O bottleneck problem and acquire better Cost / Performance I / O service people has done lots of studies on Virtual Disk Array in cluster computering system .

为了缓解I／O瓶颈，并获得有较好性价比的I／O服务，集群 虚拟 盘阵已成为人们研究的热点。

The Default Add Disk add-on creates a virtual disk on the virtual machine formats the disk with the selected file system and mounts the disk .

DefaultAddDisk附件在 虚拟机上创建一个虚拟磁盘，使用选择的文件 系统格式化 磁盘，然后装载磁盘。

The virtual appliance container is a VM image ( VMI ) . A VMI is a file that contains the VM 's hard disk image ( including the kernel boot partition and root file system ) .

虚拟设备容器是一个VM映像（VMI），VMI是一个包含VM的 硬盘映像（包括内核、引导分区和引导文件 系统）的文件。

Therefore image mapping ( a mapping from data blocks of a virtual machine disk image file to data blocks of a physical file system ) should be updated according to new file mapping to make actual mapping unchanged .

那么，镜像映射（从 存放 虚拟文件系统的 镜像文件的数据块到物理文件 系统的数据块的映射）则要根据新的文件映射进行相应的更新，以使得实际映射保持不变。

However for Windows virtual machines experiments show that virtual disk fragments cause considerable impact to system performance .

而对于Windows 系统的虚拟机，实验表明 虚拟 磁盘碎片对其I/O性能造成重大的影响。

The virtual image also contains virtual disk definition and virtual network connection units that represent the virtual resources that the hypervisor provides to the virtual system .

虚拟镜像还包含了 虚拟 硬盘定义与虚拟网络连接单元，它们代表了虚拟监管系统向虚拟机 系统所提供的虚拟资源。

You define virtual Ethernet and disk devices on the VIO Server and then make them available to the other LPARs on the system .

您在VIOServer上定义 虚拟以太网和 磁盘设备，然后使它们对 系统上的其他LPAR可用。

Development and implementation of a virtual disk server system

虚拟 磁盘服务器 系统的开发与实现

With your virtual disk created load the guest operating system into it .

在创建 虚拟 磁盘之后，就可以将客户操作 系统加载到其上。

This utility works with the kvm module using / dev / kvm to load a guest associate it with the virtual disk ( a regular file in the host operating system ) and then boot it .

这个工具可以与kvm模块协同工作，使用/dev/kvm来加载客户操作系统，将它与 虚拟 磁盘（主机操作 系统中的一个普通文件）关联起来，然后启动客户操作 系统。

The virtual disk driver accesses all of the e-files on the virtual disk . Then by analyzing and designing the reliable secure storage system of the virtual disk it gives out the overall structure and function module .

接着，通过分析设计了 虚拟 盘安全存储 系统，给出了 系统的总体构架和功能模块。

Note here that you indicate the VM which is a ReactOS operating system in Virtual Machine Disk ( VMDK ) format .

这里注意要指明VM，它是以 VirtualMachine Disk（VMDK）格式存在的ReactOS操作 系统。

At first this paper briefly introduces the foundational knowledge of cryptography . Then emphasizes the principle and implementation of two file encryption systems ( virtual disk encryption system and direct file encryption system ) .

首先简要介绍了密码学的基础知识，然后重点介绍两种文件加密系统（ 虚拟 磁盘加密 系统、直接文件加密统）的基本原理和实现方法。

Hypervisor Edition is separated into four separate virtual disks one disk each for the operating system WebSphere Application Server binaries WebSphere Application Server profiles and IBM HTTP Server that exist in the image .

HypervisorEdition被隔离到4个单独的 虚拟磁盘中，这4个 磁盘分别用于存放映像所包含的操作 系统、WebsphereApplicationServer二进制文件、WebsphereApplicationServer配置文件和IBMHTTPServer。
