最近忙于换工作

利用本站系统，弄了一个虚拟频道

http://vmware.u.blogbus.com/

 省我很多事，哈哈

注意是V2P，不是P2V！！！

在大家大谈特谈虚拟化的时候，其实包括很多用户都会为虚拟化找条退路，也就是所谓的V2P的需求。

比例：

某个应用去年一直没上线，loading很低，虚拟化了。。但是今年吞并了另一个公司，这个应用变重要了。
此时，我们如果有V2P的解决方案，就不必要重新去部署环境，浪费大量的人力物力，也解决了时间。

又或者像上次Vmware出现重大失误的时候，我们如何来防范虚拟化带来的威胁呢？

其实谈V2P的话题不多，目前主要是有几个解决方案：

1.Vmware官方推荐的是使用ghost+sysprep来实现，这种垃圾思维，基本上我们不认同也不能称之为解决方案，也许它是卖虚拟化的，所以它没必要花多少心思来推
http://www.vmware.com/support/v2p/index.html

2.基于备份操作系统的解决方案
说白了，就是备份操作系统软件，当然它同时要具备能够恢复到异构硬件平台上，之前我提到过2个软件：
BESR和Acronis True Image
http://epie.blogbus.com/logs/28919126.html

3.HP的SMP软件包，包含了V2P的功能，但是有很多前提，造成了这个解决方案无限的局限性。
    1.目标Server硬件是HP Poliant服务器
    2.目标Server的硬件version要高，基本上要G5以上才行

4. 整理中，目前还没有找到特别适合的。

Who has the most cost effective virtual infrastructure

http://www.chriswolf.com/?p=180

The Task

There’s been some interesting hypervisor pricing comparisons circulating the Internet over the past two weeks that have caught my interest:

• VMware’s Mike Dipetrillo: ESX 3.5i for Free and the Impact on Hyper-V and the SMB
• Virtualization.info - Alessandro Perilli: VMware ESXi vs Microsoft Hyper-V: which one is better for SMBs?
• EvolveTechnologies - Dave Sobel: Is VMware Cheaper than Microsoft?

After reading with interest, I set out to conduct my own pricing evaluation, thinking that it couldn’t be too hard to get vendors to agree on a fair pricing comparison (insert joke here). To keep it simple, I decided to use a small branch office consisting of six Windows Server 2003 servers in the evaluation. I consider high availability a requirement in all production virtualization deployments and added virtual infrastructure management to the mix as well. To summarize, the solution requirements consisted of:

• Virtualizing six Windows Server 2003 servers on two 2-way physical hosts
• High availability failover support
• Centralized management of the virtual infrastructure

With the criteria set, I moved to evaluating vendor solutions with each vendor’s bottom line list price.

The Proposed Solutions

Table 1 below compares what I see as comparable solutions from VMware, Microsoft, Virtual Iron, and Citrix.

Table 1: Hypervisor price comparison (assumes Windows guest OS licensing is not required)

Citrix XenServer 4.1 does not include high availability, so the Status Avance OEM was used instead. Note that the pricing in Table 1 assumes that the branch office already has existing Windows Server 2003 licenses. If licensing is required, or if plans to upgrade branch office systems to Windows Server 2008 are in place, then the pricing comparison changes substantially. The Microsoft solution already includes licensing for 8 VMs, since Hyper-V is a part of the Windows Server 2008 OS. For the three other solutions, the cheapest way to go would be to purchase six Windows Server 2008 standard edition licenses for $995 each (total cost = $5,970 for six VMs). Downgrade rights would allow you to run Windows Server 2003 under the Windows Server 2008 license, and you would already be covered when it comes time to upgrade. Note that there’s no price difference with Windows Server 2008 and Windows Server 2003 Standard Edition licenses.

Table 2 shows vendor solution pricing with the Windows Server 2008 license included (added cost of $5,970).

Table 2: Hypervisor price comparison (assumes Windows guest OS licensing is required)

As you can see, OS licensing cost is a significant factor. With the cost of OS licensing, the Microsoft Hyper-V solution changes from the most expensive to the least expensive. Also, it should be noted that both Table 1 and Table 2 reflect vendor list pricing. Since vendor discounts vary, the resulting paid price for any of the above solutions could be thousands less. Still, the list pricing comparison should give you a good idea of where each vendor stands.

The Fruit of My Labor

I had to use a minimal configuration in order to make the vendor comparisons as close as possible. VMware eloquently stated that for an apples-to-apples comparison with Hyper-V, I should include Systems Center Operations Manger and System Center Configuration Manager in the Microsoft price. However, while Virtual Center does a few things that Virtual Machine Manager doesn’t do, System Center Configuration Manger and Operations Manager can do much more than Virtual Center. So to balance the comparison, I would have to add System Center Configuration Manger and Operations Manager to the price of each solution, making the addition a wash. The same happened when backup was added to the equation. Citrix and Stratus would also argue that their solution includes local storage mirroring support, so purchasing shared network storage is not required and could represent considerable savings. VMware also noted that their price includes a year of Gold Support, and that similar support on competitive offerings could raise the price as much as 20%. Since I cannot buy a VMware product without support, I’m keeping the support cost in my comparison because it does represent the minimum price. In addition, Virtual Iron’s competitors have been quick to note that Virtual Iron does not have a similar supporting vendor ecosystem, which is a decision making factor you won’t find on a product data sheet.

So I’m sure vendors will still argue along the lines of apples-to-apples, but I counter that I am comparing apples-to-apples while agreeing that some may be tastier than others. You may see some of the solutions as granny smith apples and others as red delicious apples. On the outside, they’re all apples, but on the inside the experience is unique to each one.

Fruitless? Fruitful? I welcome your feedback.

简单浏览了下 《VMware虚拟机提速12招 》
http://virtualman.blog.51cto.com/200540/39414

整理的很到位，但是并不是所有的已上线用户都能用到这12招，我针对性整理下：

1.提升硬件环境，软件版本

2.减少虚拟的os的系统默认开销

值得学习的几点

1.不要忽略VMRC的开销

2.虚机是否有必要启用SMP，是否性能有提升。多数使用单CPU性能比较好

3.删除不必要的虚拟硬件

4.虚拟机内存和CPU配置的优化

当我们把HP Proliant的物理机虚拟到ESX中时，我们会发现一些HP agents and utilities 等没有得到清除。

暂时还没有官方的解决办法，网上找了些相关讨论

http://www.techhead.co.uk/vmware-esx-removal-hp-agents-and-utilties-after-migration

http://communities.vmware.com/thread/70682

 最新的解决方法：

脚本说明：除了手动Add/Remove Programs一些HP的程序，还有一些驻留的HP程序没有清理，

1) Create a new batch file (p2vcleaner.bat for example). The contents are listed below.
2) Create a new REG file (must be called p2vcleaner.reg). The contents are listed below.
3) Download snetcfg.exe off the Internet (http://www.jsifaq.com/docs/files/76011/snetcfg.zip)
4) Put all three files in the same directory on your freshly P2Ved VM (c:\p2vscripts for example)
5) Run the batch file.
6) Manually uninstall any HP tools that the batch file choked on.
7) Delete the P2VScripts directory.
8) Reboot

His new Vi3 book

VMware Infrastructure 3: Advanced Technical Design Guide and Advanced Operations Guide

The Amazon link is here

主要新增功能

以下信息介绍本版本 VMware Infrastructure 3 提供的一些重要增强功能：

注意：并非 VirtualCenter 和 ESX Server 的所有版本组合都受到支持，只有 ESX Server 3.5 Update 2 和 VirualCenter 2.5 Update 2 配合使用时，这些重要功能才都可用。有关兼容性的详细信息，请参见文档《ESX Server、VirtualCenter 和 VMware Infrastructure Client 兼容性列表》。

功能

• Windows Server 2008 支持 - 支持 Windows Server 2008（Standard、Enterprise 和 Datecenter 版本）用作客户操作系统。借助 VMware 内存过度使用技术和 ESX 的可靠性，可使用此全新客户操作系统让虚拟机密度达到最大，从而实现最大程度的 ROI。Windows Server 2008 不支持客户操作系统自定义和 Microsoft 群集服务器 (Microsoft Cluster Server, MSCS)。
• 增强型 VMotion 兼容性 – 增强型 VMotion 兼容性 (Enhanced VMotion compatibility, EVC) 利用 Intel FlexMigration 或 AMD-V Extended Migration 技术自动配置服务器的 CPU，简化了多代 CPU 间的 VMotion 兼容性问题，使这些 CPU 能够与旧版本的服务器兼容。在 VirtualCenter 清单中启用了群集的 EVC 后,该群集中的所有 主机都会得以配置，以便确保要进行 VMotion 的 CPU 的兼容性。VirtualCenter 不允许添加无法自动配置为与 EVC 群集中的主机兼容的主机。
  
• Storage VMotion – 支持不同 FC/iSCSI 数据存储之间的 Storage VMotion 操作。ESX/ESXi 3.5 Update 1 也增加了此支持功能。
• VSS 静止支持 - 创建 Windows 2003 客户机的静止快照时，既支持文件系统，也支持应用程序静止。而 Windows Server 2008 客户机则只支持文件系统静止。有关详细信息，请参见《虚拟机备份指南》和《VMware Consolidated Backup 1.5 发行说明》。
• 热虚拟扩展支持 - 提供虚拟机运行时扩展虚拟磁盘的功能。
• 192 vCPU - VMware 现在支持将每台主机包含的 vCPU 的最大数量增加到 192（若每台主机包含的虚拟机最大数量为 170，主机中可随时配置的虚拟软驱或虚拟 CDROM 设备的最大数量为 3）。ESX 3.5 Update 1 也增加了此支持功能。

VMware High Availability (HA)

VirtualCenter 2.5 update 2 增加了根据 VMware Tools 检测信号监控单个虚拟机故障的完全支持。本版本还增加了对群集可以包含 ESX 和 ESXi 主机的混合组合的支持，从而最大程度的降低先前配置对 DNS 的依赖性。

VirtualCenter 警报

为了将每个系统组件（例如，内存和电源）的健康考虑在内，VirtualCenter 2.5 Update 2 新增了对服务器总体健康状况警报的支持。现在可以将警报配置为在主机健康状况降低时触发。

管理代理支持

• HP 管理代理 - HP Insight 管理代理为受支持的服务器平台上的 ESX Server 主机提供服务器管理功能。现在支持新版本 8.1。

虚拟机世界一定会很关注这条消息,由于受到微软Hyper-V以及Citrix's Xen等虚拟机市场的强大压力,VMware宣布ESX 3i软件免费.
一台集成了ESX Server 3i的PC服务器就像插了一块提供虚拟化功能的硬件卡,不再需要安装任何软件,就可以直接部署在虚拟化环境,通过Virtual Center对其进行管理,享用虚拟化的各种功能.

保护、简化和加快服务器虚拟化

VMware ESXi 是业界第一个与硬件集成并构建于新一代精简体系结构之上的管理程序，它为您的企业建立动态、自动化的数据中心提供了高效基础。

VMware ESXi 代表了实现虚拟化愿景方面的重大进步，它不仅为 x86 服务器提供了标准计算平台，还通过与服务器硬件的集成进一步简化了 IT 运营。
VMware ESXi 的主要优势
增强的安全性和提高的可靠性

VMware ESXi 是唯一一个既不属于也不依赖通用操作系统 (OS) 的管理程序，可以避免大量可靠性方面的常见问题和安全漏洞。VMware ESXi 精简的 32M 占用空间只是通用操作系统所占空间的一小部分，这使得在最大程度减少完成诸如安全强化、用户访问控制、反病毒和备份等任务所需的工作量的同时，受攻击范围更小。此外，与服务器内部固态组件的集成可实现无磁盘的服务器配置。这不仅降低了硬件故障率，还减少了服务器电力消耗。

简化硬件资源和虚拟机主机的管理

VMware ESXi 提供了管理服务器计算节点的简化方法， 通过一组 基于标准的强大 管理功能，将您从本地管理任务中解放出来。除了免去安装步骤并简化配置之外，VMware ESXi 还通过 Common Information Model (CIM) 为硬件资源提供了无代理、基于标准的监控功能。您也可以将集成的远程命令行界面 (CLI) 用于存储、网络和主机配置，以及维护、修补程序和更新。
在数据中心启用即插即用容量管理

使用 VMware ESXi，您可以快速部署现成准备好运行虚拟机的新服务器。VMware ESXi 中的自动配置功能提供了检测、发现和智能默认配置，所采用的菜单驱动启动方式让您可以在几分钟内完成从启动服务器到运行虚拟机的过程。 将您的新服务器插入到虚拟基础架构中，通过迁移虚拟机并以最佳方式负载平衡资源池，让 DRS 自动管理您的新容量。
