Microsoft Hyper-V Dell PowerEdge 2900 Problem Fixed
I just ran into a problem where Microsoft’s Hyper-V role would not install on a 2008r2 x64 Dell PowerEdge 2900. I had a VT-capable processor and VT enabled in the BIOS.
Turns out, the BIOS settings were backwards — if you DISABLE VT in the BIOS it is actually enabled. Disabling VT in BIOS allowed me to install Hyper-V.
This is with the latest PowerEdge 2900 BIOS (v 2.6.1) and 1 dual-core Xeon CPU. The problem also existed with BIOS version 1.5.1
