KB2636573 – Hyper-V Guest OS May Crash When Performing Live Migration

I can’t say I’ve ever seen this one, but worth installing this new bugfix update for preventative maintenance.

In a Windows Server 2008 R2 environment, you perform a live migration of Hyper-V virtual machines. In this scenario, the guest operating system may crash. Additionally, you receive a Stop error message that resembles the following:

STOP 0x000000D1 (parameter1, parameter2, parameter3, parameter4)
DRIVER_IRQL_NOT_LESS_OR_EQUAL

To resolve this problem, install this update on the host computer where the Hyper-V virtual machines are located.

  1. Finally….seen this for a while now, usually when I put a host in maintenance mode and many VM’s moved in a row. Only Windows 2008 R2 VM’s did this.
