Hyper-V Update reverting when installing via Windows Update

While installing the update to Hyper-V RTM the installation would seemingly finish successfully, but then threw an error during the reboot while configuring the updates. To solve this we tried to shut down all the VMs and stop all the Hyper-V related services, but even this did not help. Eventually we completely removed the Hyper-V role, installed the updates, re-added the role and all was fine.

It meant having to reinstall all of the Integration Services components on each of the VMs, but at least their settings were largely still in tact, except for the need to recreate the Virtual Network and set that accordingly on each VM.

Migrating Virtual Server 2005 to Hyper-V

There are a lot of blog posts out there about this, but as a summarised and by no means conclusive list, I would advise:

• Ensuring all Virtual Machines are fully service packed and updated
• Uninstalling the Virtual Machine Additions from your Virtual Server 2005 VMs
  • This is required before the Integration Services can be installed for Hyper-V which is a must for network support and proper control of VMs amongst other things
• Understanding the different approach taken with Hyper-V virtual networking including the use of the virtual switch
  • External, Internal and Private
• Enabling Virtualisation Support via your BIOS if not done already
  • When enabled this seems to slow Virtual Server down hugely, but is required for Hyper-V
• Fully updating your Parent Partition Operating System

Also if you want to manage Hyper-V from you Vista Workstation I would install the Windows Vista Service Pack 1 Management Tools update for the release version of Hyper-V which you can download from...
