Upgrading Hyper-V (pre-release to RTM)

A few nights ago, I finally got around to upgrading my own Hyper-V installation from release candidate 1 to the RTM version. I’d already updated the notebook PC that I use for work but I’d forgotten about the server at home – it was working well (and if it ain’t broke…). What follows explains the process for upgrading a server that is already running a pre-release version of Hyper-V to the RTM code:

  1. On the parent partition, run the 64-bit version of Microsoft update 950050. This will update the Hyper-V components and will require a restart. After the restart, the version of Hyper-V Manager should be 6.0.6001.18016.

  2. On each virtual machine, upgrade the integration components ICs – also known as integration services). To do this:
    • Connect to a VM using the Virtual Machine Connection (VMC) tool and log on.
    • Cancel the Found New Hardware Wizard and select Insert Integration Services Setup Disk from the Action menu in the VMC tool.
    • A previous version of the Hyper-V integration services should be detected. Click OK to upgrade.

    • When the integration services have been upgraded, restart the virtual machine.
    • Following the restart, there should be no new hardware detected and all synthetic devices (e.g. the Microsoft Virtual Machine Bus Network Adapter) should be at version 6.0.6001.18016.

The process is time consuming and it does involve restarting every computer in the virtualised infrastructure, which should not be surprising as it also involves some pretty deep changes in the operating system (this upgrade is also from a pre-release version of Hyper-V, which implies it’s not running a production workload).
