Some Hyper-V Basics

Here is the answer to an inquiry about Hyper-V when starting from ground zero.

  • Overview
    • RAID 10 is your best friend (lots of I/O) but needs at least 4x drives.
    • 16GB of RAM is better.
      • Gives access to 8GB for SBS 2008+ and a couple of clients including RD RemoteApps on TS and a couple of 7s.
    • Register a domain, or set up a DNS A record for and purchase the GoDaddy cert for that URL.
      • Have an ISP IP handy for it so that one can test things from the Internet which is critical to understanding how things work.
  • Hyper-V
    • Hyper-V on Windows Server 2008 Full
      • GUI install means more updates.
      • GUI install means security openings not in Core.
    • Hyper-V on Windows Server 2008 Core
      • Command Line means less updates (There were about 8-12 in the last 6 months that were applicable).
      • Tougher to configure though we do have a guide.
      • Less OS load means more CPU cycles available for Hyper-V = better VM performance.
  • Hyper-V Server 2008 R2
    • Has a built-in “GUI” to eliminate much of the CL work.
      • SConfig on R2 Core with Hyper-V brings up the same.
    • Blog Category list of posts
      • Note the binding order post is important for both Core and H-V Server.
    • Clustering and all of its features are available in this free addition.
  • P2V
    • We have used StorageCraft for restores to H-V.
      • Only one vCPU can be assigned during the restore or performance suffers.
      • Legacy NIC required for initial restore if networking is critical.
      • Hardware clean-up steps same as Hardware Independent Restore clean-up steps.
    • We have used the built-in SBS 2008/v7 backup for restores to H-V.
    • We have used the built-in Windows Server 2008+ for restores to H-V.

The above is an overview or guideline that can be used to build out an understanding of how to work with Hyper-V in all of its iterations.

Other than more cores is always better for the host, the above should be a good start.
