I have been trying to upgrade our windows server 2012 installation that is running hyper-v, but have a problem with the physical nic. The issue is that upon finalising the upgrade, WinSer2012R2 presents a BSOD (IRQL_NOT_LESS_OR_EQUAL) and the only hardware device I cannot remove prior to the upgrade is the NIC so I assume this is giving me the grief.
I have tried to remove the NIC driver, but Hyper-V depends on it (all vPcs depend on it as well as a logical switch).
How can I remove the physical NIC? Is my only option to reconfigure all vPcs to have no NIC and delete the logical switches? This is a lot of work to reconfigure and error prone as well.
I would have checked log files for the boot, but for some reason, WinSer2012R2 does not create any log entries or memory dumps for me to look at. So all I have is the above mentioned BSOD hint.
Suggestions?
