kvm 英'keɪv'iː'em美'keɪv'iː'em COCA²⁸⁰¹³⁶⁺⁵ 基本例句 abbr.=kilovolt meter 千伏计¹⁰⁰;Switch Keyboard Video Mouse Switch;KVM 交换机 The guest operating system interfaces to the KVM module using a modified QEMU process for PC hardware emulation. 客户操作系统使用为 PC硬件仿真修改过的 QEMU进程与 KVM模块接口。 ibm The two biggest drawbacks to KVM are that it requires newer virtualization- capable processors and a user- space QEMU process to provide I/ O virtualization. KVM两个最大的缺点是需要较新的能够支持虚拟化的处理器,以及一个用户空间的 QEMU进程来提供 I/ O虚拟化。 ibm The KVM module introduces a new execution mode into the kernel. KVM模块向内核中引入了一个新的执行模块。 ibm With KVM installed, you can start guest operating systems in user- space. 安装 KVM之后,您可以在用户空间启动客户操作系统。 ibm Another advantage to KVM is that because it's part of the kernel itself, it can take advantage of kernel optimizations and advancements. KVM的另外一个优点是它是内核本身的一部分,因此可以利用内核的优化和改进。 ibm As previously mentioned, KVM uses the underlying hardware's virtualization support to provide full native virtualization. 如前所述, KVM使用底层硬件的虚拟化支持来提供完整的原生虚拟化。 ibm Because KVM virtual machines are regular processes, the standard memory conservation techniques apply. 由于 KVM虚拟机是常规进程,可以使用标准内存转换技术。 ibm Even though KVM has been out for only a short time, you can find several articles exploring its performance in several areas. 尽管 KVM的出现时间非常短,但是您可以找到一些介绍其各个方面性能的文章。 ibm Figure2 provides a view of virtualization with KVM. 图2提供了一个使用 KVM进行虚拟化的视图。 ibm Further, KVM isn't really a full virtualization scheme by itself but rather a piece of a larger solution. 另外, KVM不再仅仅是一个全虚拟化解决方案,而将成为更大的解决方案的一部分。 ibm IBM has a heterogenous approach toward virtualization, with KVM one of several options. IBM对虚拟化的推进来自于不同的途径, KVM也是其中之一。 infoq In this article, we will focus on CLDC and KVM architectures. 在本篇文章中,我们将把注意力放在 CLDC和 KVM体系结构上。 ibm QEMU is an open source processor emulator that also provides the PC environment virtualization capabilities for KVM. QEMU是一个开源处理器仿真器,它也可以为 KVM提供 PC环境虚拟化功能。 ibm QEMU works in concert with KVM to offer platform emulation and individual device emulation to provide the platform for KVM-based virtualization. QEMU和 KVM一起运作,提供平台模拟和独立的设备模拟,为基于 KVM的虚拟化提供平台。 ibm Recall that KVM is part of a virtualization solution. 记住 KVM只是虚拟化解决方案的一部分。 ibm Recently, a modification to the kernel was made called the Kernel-based Virtual Machine KVM. 最近,对内核进行了修改,称为基于内核的虚拟机 KVM。 ibm The tool is deployed in a typical KVM environment and manages two distinct workloads. 此工具部署在典型的 KVM环境中,并管理两组不同的工作负载。 ibm There are two approaches to creating guests for use by KVM. 有两种方法可以为 KVM创建客户机。 ibm This modification enabled a new interface to user space that allows other operating systems to run above the KVM- enabled kernel. 这个修改为用户空间启用了一个新的接口,它可以允许其他操作系统在启用了 KVM的内核之上运行。 ibm Today, KVM has a very effective cooperative CPU- sharing mechanism. 现在, KVM有一种可有效协作的共享 CPU机制。 ibm Using KVM is actually quite simple if your hardware supports it. 如果硬件支持的话,使用 KVM实际上非常简单。 ibm While the host is managing the memory allocated to a KVM guest, the guest kernel is simultaneously managing the same memory. 当主机管理分配给 KVM客户的内存时,客户内核也同时在管理相同的内存。 ibm While simple, this process illustrates how you can instantiate new guest operating systems with KVM. 尽管这个过程非常简单,但是它解释了如何使用 KVM实例化新客户操作系统。 ibm You can deploy KVM-based virtualization in a myriad of configurations using architectures designed to meet different goals. 您可以部署基于 KVM的虚拟化,进行各种配置,使用可满足不同目标的架构。 ibm You've successfully created a virtual server built on KVM. 您已经成功创建了一个基于 KVM的虚拟服务器。 ibm Your choice of hardware and software may be different, but the main hardware criterion is that your processor should have hardware virtualization available— it's a must in order to use KVM. 选择的硬件和软件可能有所不同,但是主要的硬件标准是您的处理器应当具有硬件虚拟化特性—这是使用 KVM的必要条件。 ibm KVM is also considered a full virtualization solution, but I explore this later. KVM也被认为是一个全虚拟化解决方案,不过我们稍后再介绍这个问题。 ibm KVM is an interesting solution to the virtualization problem, but as it's the first one into the kernel, it's hard not to imagine that it will gain ground quickly for server virtualization. KVM是解决虚拟化问题的一个有趣的解决方案,但是由于它是第一个进入内核的虚拟化解决方案,很难想象它会很快用于服务器虚拟化。 ibm KVM simply ignores this problem and mandates that if you want virtualization, you'll have to run on newer hardware. KVM会简单地忽略这个问题,如果您希望进行虚拟化,就强制必须在更新的硬件上运行。 ibm But KVM isn't the first to do this. 但是 KVM并不是第一个这样做的程序。 ibm |
