Virtualization offers huge benefits in flexibility, cost-effectiveness and eco-friendliness. However, some design choices need to be made towards deploying Active Directory Domain Controllers in virtual environments. Some of these choices are general choices, but some of them apply to Hyper-V enabled environments specifically.
When deploying an Active Directory environment, either for test or production purposes, either virtual or physical, be sure to deploy at least two Domain Controllers per Active Directory domain, whenever possible. When either Domain Controller fails you don't lose your Active Directory information and any applications, services and users depending on it can continue to operate, unless specifically pointed to.

Last month at the BUILD Conference we introduced Windows Server 8 and began discussing how it will help customers deliver the most dynamic, available, and cost-effective server platform for what we call "cloud optimized IT." I wanted to follow up on Bill Laing's blog post and dig into the advancements in our Hyper-V virtualization role, which provides a complete virtualization platform, increased scalability and performance, and connectivity to cloud services.
Using Windows Server 8 Hyper-V, organization can deliver fully isolated, multi-tenant clouds, enable high scale and low cost data centers and provide the most manageable, extensible and interoperable platform for cloud. Below are just a few examples of some new and enhanced features in the Windows Server 8 Developer Preview that support a complete virtualization platform and provide the best platform for the cloud.

SUMMARY 

A virtual hosting environment lets you run multiple guest operating systems on a single host computer at the same time. Host software virtualizes resources that include the following:

  • CPU
  • Memory
  • Disk
  • Network
  • Local devices
By virtualizing these resources on a physical computer, host software lets you use fewer computers to deploy operating systems for test, for development, and in production roles. However, certain restrictions apply to the deployment of Active Directory domain controllers that run in a virtual hosting environment. These restrictions do not apply to a domain controller that runs on a physical computer.
