HyperV clearly has a whole lot of advantages and there might be various numbers of reasons why many set up HyperV environment and prefer it too. You can best utilize the benefits of HyperV without compromising on the 64 bit compatibility. It is possible to facilitate product evaluations, test labs testing and learning environments too with the help of HyperV. If you are aware, HyperV works on entry level 64 bit hardware too. However, the CPU capacity and the latest BIOS update must be available in order to support the hardware virtualization.
With complete supported software versions, you can now make a blast to deploy or organize full scale test environments. You can even use even the 64 bit version of the exchange server 2007 from the Microsoft. Once you are done with the initial set up of the deployment, you may easily redeploy every time you need to begin from the basics or if you have to check on a new product or even when you want to start a new training or class session. This could be done easily anytime you want to do thus exhibiting the advantage of HyperV.
Imagine a situation where your customer has two domain controllers or DCs and that you are deploying a test environment. Say your customer also has SQL server running with two SharePoint front end servers, a hub transport server, an exchange mail box server 2007 and a client access server. With all these combination, it is certainly going to take a lot of effort. However, if you have a better and large environment, say for instance with 600 virtual machines, you can easily reinstall the VMs every time or every week you want or even every time a new lab environment is required. Such deployments are very important when you want to automate. Thus HyperV makes a whole lot of difference.
HyperV is basically a windows technology. It is easy to combine HyperV with WMI or Windows Management Instrumentation, WDS or Windows Deployment Services, Windows Power Shell, AIK or Windows Automated Installation Kit and PE or Pre-installation Environment 2.0. With these you can enable deployments at full scale just at a wink of your eye which means it takes much lesser time. Watching the installation screen and the progress bar when the system is deploying and configuring them is definitely an interesting aspect. However, this may not be your priority. Thus HyperV is definitely makes life easy.
You can also deploy HyperV servers, Virtual Machines, server applications without interaction from any administrator, guest operating systems using WDS, unattend.xml files, customer install images and WMI scripts. The idea behind this is to pre-configure WDS environment first for once and later installs test systems based on requirement. The same applies with reinstalling teaching environment, developing, testing customer solutions and troubleshooting various critical issues under different configurations. To launch the preboot execution environment, also known as PXE, you just need to press the F12 key in order to interact while deployment. If you are using the Startrom.n12, you may even skip this step. Earlier default Startrom.com was used in WDS configuration.
