DL380 G5 -Hyper V on windows 2008 R2 fails to work.

[stephen.ni]

Let me start by saying we have just flashed the BIOS, and verfied the reginal settings, since these were the first answers I found on a google search.

The problem is on a clean install of Windows 2008 R2, on a DL 380 G5 server, with all current critical updates, we installed Hypervisor. But when we try to build a new virtual machine, we get the following error:

'Hypervisor' driver required by the Virtual Machine Management service is not installed or is disabled. Check your settings or try reinstalling the Hyper-V role.

We have verified that Hyper-V is enabled in Bios. The Bios is flashed to the 9/2009 update.

The DL380 G5 has the needed technology.
All the services (3) say they are running, but you can't actually launch a virtual machine, without that error.

Any input would be Appeciated.

Make sure you have windows firewall disabled....

BTW, regional settings was issue only with win2008 without R2, in R2 it's solved

Firewire was on, so I turned it off.
Problem Persists.

Rebooted, but problem persists.

ran the following, which I found on the MS technet website:

netsh advfirewall firewall set rule group="Remote Volume Management" new enable=yes

Did you set DEP - No-Excecute Memory Protection flag as well ?
And you must power off - power on server after these changes in BIOS

That was the Problem. The second BIOS Setting. I even looked it over, and pressed F1 on that item, but it did not say anything about being related to Hyper-V Technology.

The problem is now solved. We will make a note of this setting for HP servers.

Thanks.
