Quick Fix: Enable Hyper-V on HP ML 310 G5..

OK so i wanted to virtualise two systems in our office on an HP ML310 G5.

I installed Windows 2008 Enterprise R2, enabled the hyper-v role, did a P2V transfer of the first system (XP SP3) got everything ready, when i tried to start the machine i was hit with a message about the Hypervisor not running.

I did a quick google search and found a post that told me to go into the BIOS and make sure the Intel Virtulisation technolgoy was enabled, i rebooted and entered the BIOS,

Advanced Settings > Processor Options > Intel V…

Changed to enabled, and rebooted.

No Change.

At this point i was working remotley through ILO, when i discovered you needed a cold boot of the system (full power off, power removed!)

So i had to wait until this morning to do that.

I removed the power, booted up, but no, HyperV not running.

Getting more than a little frustrated i removed and reinstalled the Hyper-V role, adding extra reboots in just make sure… No change.

Again i hit google, i came across this post..

Which explains to enable another option in the BIOS, No-Excecute Memory Protection.

I rebooted and enabled this, logged back into my System and BINGO!

We have a working Hyper-V system.

I find it a little odd that my ML 310 – needed this doing, when my ML110 G6 worked out of the box, but there you go!

Hopefully this will save you some time.
