HP virtualization manager, HP Capacity Advisor, and virtual Machine migration (for IVM's) allow a running VM and its applications to be moved to a different VM host without service interruption.
hp虚拟化管理器、HPCapacityAdvisor和虚拟机迁移(针对IVM)支持在中断服务的情况下将正在运行的VM及其应用程序移动到不同的VM主机。
As you see in Figure 1, the hypervisor is the layer of software that provides the virtualization of the underlying machine (in some cases, with processor support).
在图1中可以看到，hypervisor是提供底层机器虚拟化的软件层(在某些情况下需要处理器支持)。
The administrator simply declares that a given machine can no longer be used and the WebSphere Extended Deployment virtualization system ADAPTS automatically.
管理员只需声明不能继续使用指定的计算机，WebSphereExtendedDeployment虚拟化系统会自动适应这一声明。
In a typical layered architecture, the layer that provides for the platform virtualization is called the hypervisor (sometimes called the virtual machine monitor, or VMM).
在典型的分层架构中，提供平台虚拟化的层称为hypervisor(有时称为虚拟机管理程序或VMM)。
The System/390 architecture allowed complete virtualization of the machine, including even the "privileged" instructions that simply ran inside the sandbox created for them.
System/390架构支持机器的完全虚拟化，甚至包括只能在为虚拟机创建的沙箱中运行的“特权”指令。
Figure 1 shows that the virtualization component is provided by a layer of software called a hypervisor (sometimes called a virtual machine monitor [VMM]).
图1中所示的这个虚拟化组件是由一个名为hypervisor(有时也叫作虚拟机监视器[VMM])的软件层提供的。
If you have any intention of serving users with more than one OS, you'll want a test machine with some form of virtualization on board.
如果您打算使用多个操作系统为用户提供服务，那么需要在测试计算机上实现某种形式的虚拟化。
An important feature of virtualization is the dynamic configuration and reconfiguration of the logical partitions without need for rebooting the entire physical machine or disturbing other partitions.
虚拟化具有一个重要的特性，在对逻辑分区进行动态配置和重新配置时，无需重新启动整个物理计算机，也不会影响到其他分区。
This lets administrators deploy and move application servers at a virtualization layer level instead of at the physical machine level.
