虚拟化技术已经在很多场合中应用过了，但现在主要的关注点是服务器和操作系统的虚拟化。
It has been used historically in a number of contexts, but a primary focus now is in the virtualization of servers and operating systems.
每个操作系统都使用自己的虚拟机，虚拟机与管理器协作，从而决定对物理硬件的访问(见图2)。
Each operating system USES its own virtual machine that cooperates with the hypervisor to arbitrate access to the physical hardware (see Figure 2).
虚拟化最常用的方法是整合服务器，以便提高服务器利用率，并减少操作空间和能量损耗。
The most common motivation for virtualization is consolidating servers to improve server utilization, and to reduce operational space and power expenditures.
服务器虚拟化是对最终用户隐藏服务器资源（比如物理服务器、处理器和操作系统）的过程。
Server virtualization is the process of hiding server resources such as individual physical servers, processors, and operating systems from end users.
不好的一面是，由于虚拟化软件互操作性方面的问题，虚拟化后的服务器有可能不能从一个厂商转移到另一个厂商。
One downside is that virtualized servers may not be transferable from one vendor to another due to interoperability issues of the virtualization software.
然后可以部署它，创建包含完整操作系统和软件应用程序的新的虚拟服务器，或者覆盖现有的虚拟服务器。
You can then deploy it to create a new virtual server that is complete with a fully functional operating system and software applications or overwrite an existing virtual server.
当数据库服务器处于联机状态并执行操作时，如果虚拟区的初始尺寸太小，数据库服务器会自动向虚拟区附加其他操作系统段。
When the database server is online and performing operations, it automatically attaches additional operating-system segments to the virtual portion, if the initial size is too small.
QEMU是一个平台虚拟化应用程序，让您能够仿真完整的计算机（处理器和相关的外部设备），用于在其上虚拟化另一种操作系统。
QEMU is a platform virtualization application that allows you to emulate an entire computer (processors and associated peripherals) for purposes of virtualizing another operating system on it.
捕捉正在运行的虚拟服务器，从而获得访客操作系统、正在运行的应用程序和虚拟服务器定义。
Capture a running virtual server that is configured just the way you want, complete with guest operating system, running applications, and virtual server definition.
虚拟处理器是操作系统计划处理的进程。
A virtual processor is a process that the operating system schedules for processing.

虚拟化技术能够解决这个问题，它能够创建虚拟服务器，虚拟服务器上可以运行多个操作系统及其应用程序。
Server virtualization solves this problem by creating a virtualized server on which many operating systems (and their applications) can run.
一个操作系统类型、一个虚拟服务器系统(或如果您在运行LPAR的话是服务器类型)，状态应当没有问题。
One operating system type and one virtual server type (or server type if you're not running on LPAR), the status should be OK.
为了实现虚拟处理器上下文切换成本的最小化，操作系统将告诉Hypervisor是否正在使用某些资源。
To minimize the cost of a virtual processor context switch, the operating system indicates to the hypervisor whether some resources are in use.
