Hyper-V VMs unloaded after installing Windows Updates

November 19, 2008

I can’t prove it that it was an update that caused it, but after applying these updates: KB954430, KB890830, KB958644, KB957097, KB954459 and KB955069, Hyper-V showed no available VMs though just before installing the above, I had one loaded which had been running for a couple months. The VHD was still on the server, I just had to tell Hyper-V about them again. Strange.
