Updating your Virtual Machines and SCVMM to support Hyper-V RTM

  • Artikel

Today I finally found the time to update my demo environment which was still based on Hyper-V RC0 and SCVMM 2008 Beta. I want to share all the steps needed to perform the upgrade and updates. My demo environment consists out of 3 physical servers, one dc and two Hyper-V machines all in the same domain. My SCVMM 2008 Beta is running as a virtual machine on Hyper-V.

First of all I’ve deleted all my snapshots and then updated my Hyper-V machines to RTM by installing the KB950050 which is now available through windows update. Installing this update requires a reboot and also make sure to take the following guidelines into consideration:

  • Saved state files are not supported between the Release Candidate (RC) and the release version of Hyper-V. All virtual machines should be shut down correctly before you install the release version of Hyper-V.
    Note If you have already applied the release version of Hyper-V, virtual machines in a saved state will not start.
  • Snapshot files are not supported between the Release Candidate (RC) and release version of Hyper-V. All virtual machine snapshots should be deleted by using the "Delete Snapshot Subtree" option for each virtual machine.
    Note After you delete the snapshots and after you shut down the virtual machines, the changes that exist in the snapshot files (.avhd files) will merge into the parent virtual hard disk file (.vhd).
    This operation can take a while. To verify that the snapshots have merged into the parent virtual hard disk file, locate the snapshots, and then verify that no .avhd files exist.

Note The saved state and snapshot files are compatible if you are upgrading from Release Candidate 1 (RC1) to the release version of Hyper-V.

The next step is to install the same patch onto my Domain Controller so I have the new Hyper-V management tools installed.

So I have now updated my 3 physical machines to the latest updates and in the next steps I will update all my virtual machines.

The last step in the process is to install the SCVMM 2008 patch, unfortunately I found out that I had an older version of SCVMM Beta (2.0.3193.0) running and I had to upgrade this one to the latest beta version (2.0.3194.0) and then apply the patch needed to support Hyper-V RTM. The SCVMM patch can be found onto connect.microsoft.com

The upgrade process is pretty straightforward and takes not much time but be aware of the reboots needed.
