Deploy essay the virtual machines to the host computer and start the images. Monitor the consumption of book resources, especially disk and memory. The Dreaded Windows Server 2008 Licensing Rules for Hyper-v in practical terms, favour the Enterprise edition of Windows Server 2008 as licensing allows you to install up to 4 Enterprise guests on an Enterprise host. However, do double-check as Microsoft's licensing will never be my area of specialist interest. Microsoft's Application Virtualization Finally, a few words about Microsoft's Application Virtualization, also known as SoftGrid. . The Application version, is a more fine-grained solution that complements Hyper-V. . Instead of virtualizing the whole operating system, Application Virtualization creates multiple instances of just your applications. So obtain the Application Virtualization package you need to subscribe to the software Assurance package. . Else check the rules at Microsoft's site. Summary of Virtualization in Windows Server 2008 Whether you call it wsv or Hyper-v, this new virtualization technology means that you can use windows Server 2008 to parent numerous child virtual servers.
Ideas for Placing Virtual Machines to optimize your virtual machines, begin by collecting performance information about the existing physical paper computers. . (you could use system Center Operations Manager (scom) 2007.) Check the resource requirements for the configuration of the virtual machine. Gestimate the number of simultaneous virtual machines the host computer can run. Remember factors such as total memory (allow 512MB for the parent partition number of virtual processors, virtual hard disk storage, and network connectivity. You could consider load balancing. . to optimize load balancing, assign virtual computers to two host computers so that each host computer should experience approximately equal resource usage. Plan to convert all physical computers to virtual machines.
Once you add an existing vhd, legs you can then start the real work of configuring such basic vhd installations to your own specifications. Monitor your Network with the real-time Traffic Analyzer The main reason to monitor your network is to check that long your all your servers are available. . If there is a network problem you want an interface to show the scope of the problem at a glance. Even when all servers and routers are available, sooner or later you will be curious to know who, or what, is hogging your precious network's bandwidth. . a gui showing the top 10 users makes interesting reading. Another reason to monitor network traffic is to learn more about your server's response times and the use of resources. . to take the pain out of capturing frames and analysing the raw data, guy recommends that you download a copy of the solarWinds free real-time netFlow Analyzer.
Obviously, you can always add more ram later should you need more virtual servers than your initial plan indicated. One key point, interrupt the hyper-V wizard when it asks for Name and Location. . Instead of accepting the defaults, create your child operating systems on a different partition from the parent. . see screen shot to the right. The wizard will also reveal that each child has its own enormous vhd file (Virtual hard drive this may lead you be on the lookout for existing vhds which you can add to your parent. This technique saves the time needed to install the basic operating system; somewhat like using sysprep or ghost images to install previous operating systems. Another way of thinking about a pre-formed vhd is that you are adding a foster child to your parent, rather than giving birth to child by installing the operating system from scratch. . As for the nature of these child operating systems, they could be windows Server 2003, server 2008, or even Linux.

When you buy summary your Windows Server 2008 Product key, make sure you order the meaning 64bit version as the parent Hyper-V will only install on a 64bit version of Server 2008. . Child virtual servers can be all sorts of 32bit operating systems.
How to Install the virtualization Service When you install the parent or host Virtual server, microsoft recommend that you install the server Core role (rather than the normal gui). . This is for practical and security concerns, rather than an essential requirement for the parent host. My favourite way to connect with the core server is with a remote connection. Begin by launching Server Manager, and then click on add Role to install Hyper-V. Windows Server Virtualization (WSv) As usual, ram is the limiting factor for multiple machine configurations, so don't skimp on memory for a production machine. For each Child virtual machine allow 2gb of ram (800 mb is the absolute minimum). .
i am a great believer it trying server configurations in a virtual world before unleashing them on a live network. Let us be realistic here, 80 of the forgoing advantages will be useless to you. . Yet one will be a little gem, which makes it well worth the effort of setting up a hyper-V parent and adding child roles. . While i don't work for Microsoft, i do like to keep my eye on this trends, virtual pc - virtual Server 200x and now - hyper-V. . I see a pattern, and I see evolution. .
to switch metaphors, this is a gravy train I want to ride for a while. Parent Hardware requirements If you are just testing Windows Server 2008's Hyper-V then you may be able to 'get away' with sub-optimal hardware. .

Download Free trial eliminate the guess Work of Virtual Capacity Planning Microsoft's Thinking Behind Virtualization Research shows that many servers aren't used at their optimal capacity. Some surveys suggest the average utilization may be only. Therefore why shredder waste money buying five servers when you could buy one? . If you follow this logic, expect additional benefits in the form of less power consumption and less heat production. . you may also save money on spares, repairs and even insurance. Furthermore there is the notion that Virtualization encourages more flexibility. If the email server is stressed then create an extra virtual server. . If the three servers in the web farm are under-employed, then just stop two of these virtual servers. As reviews Virtualization started life as a training and testing role, you could continue to foster these roles in Windows Server 2008. .
be one of your virtual servers, for example, a virtual machine performing the role of a domain controller, or an email server. . Crucial concept: the child does not have its own hardware separate from the parent. A clever layer that isolates the parent and child partitions from the physical hardware on the host computer.vhd is a huge physical file that holds all the disk data for the child operating system. . never miss the chance to collect a free. Vhd download from. (you will still need a licence!).
Whereas Virtual thesis pc and Virtual Server 200x were primarily for testing, training, or trying out ideas; this Windows Server 2008 Role is the real deal for virtualizing a whole production network. . Some network managers really will be running their organization from one parent core server, which hosts a handful of child virtual servers, such as, email, database, domain controller or file print. Windows Server 2008's 'virtualization' terminology, the idea of Virtualization is to emulate, or host, an entire computer environment within the operating system of another computer. . Here are some related terms: wsv (Windows Server Virtualization) The whole concept of virtualization. Hyper-V (Code name viridian). . means very nearly the same thing as wsv.

Configurations range from a single parent with two child virtual servers, all the entry way up to 8-way clustering and dynamic. Incidentally, hyper-v virtualization is the number one reason to migrate from W2K3. Topics for Virtualization (Hyper-v learn From Virtualization's evolution, with Microsoft's virtualization, it is even more useful than usual to review the evolution of this technology. . The twin reasons to review the past are, firstly, you may have already experimented with Virtual pc, or Virtual. Server 200x and thus already have some inkling of the concepts of this virtual world. . Secondly, before you commit to window. Server 2008 virtualization you may wish to practice with one of the cheaper virtual options.
