Hyper-V Program Manager
We released a new hotfix for Hyper-V today.
This hotfix addresses an issue where virtual machines may crash (with a STOP 0x000000D1, DRIVER_IRQL_NOT_LESS_OR_EQUAL error) when it is being live migrated. While this problem is relatively hard to encounter – I would encourage anyone who is using live migration to plan to deploy this hotfix in the near future, as you do not want to hit this accidentally.
You can download this fix directly from here: http://support.microsoft.com/kb/2636573
Alternatively, it is also being distributed through Windows Update. Unfortunately it is only available as an optional update though – so you will need to explicitly select to install it on your servers.
Either way, this hotfix does require that you reboot the physical server so you will need to plan the deployment of the fix appropriately for your environment.
A similar BSOD* error shows up as soon as a brand new VM (no OS) created using Windows Virtual PC with default settings is started on Windows 7 Ultimate x86 en-us (no SP1). The issue remains even after updating to Win 7 SP1 on the host machine.
Likewise when Windows XP Mode is being created, the host machine went BSOD.
Is there a separate fix for this, especially on x86 32-bit machines? Note that the latest drivers (network, system, etc.) are deployed.
Thanks / rgds,
