HyperV role complain about virtualization not being enabled but it is.

[Patric Falinder]

Hi,

We recently got three new DL360 Gen10 Plus which I have installed Windows Serve 2022 on.
I just got ready to install the HyperV role on them but I get an error saying "Hyper-V cannot be installed because virtualization support is not enabled in the BIOS":

But my BIOS/UEFI settings looks like this:

What am I missing here?
I installed Windows through Intelligent Provisioning so all the right drivers etc. are installed.
I can't figure out why it's complaining about this when it clearly is enabled already.

So I just noticed that the options in BIOS are greyed out. No matter what I do I can't change them.
Even though they show as Enabled it seems to be disabled.

I just checked on the host and it says that Virtualization is disabled as well..

Hi Patric,

I assume workload profile applied might have disabled the virtualization option, please check the below URL about workload profile and switch over to either Virtualization - Power Efficient or Virtualization - Max Performance workload profile.

To Select:

From the System Utilities screen, select System Configuration> BIOS/Platform Configuration (RBSU)> Workload Profile

Refer Document on Workload Profiles URL:  UEFI Workload-based Profiles and Tuning Guide for HPE Servers 

I hope this will resolve the issue

Thanks

Thanks for the reply. I already had it set to Virtualization - Max Performance from the beginning. I also tried switching to other profiles but the options are still greyed out.

I just tried to reset to default and then the options are not greyed out anymore. I tried switched to Virtualization - Max Performance and now it works. So I'm guessing there was some setting I made at first that messed this up.

Weird, I had to do the same thing, reset BIOS to Defaults and my HyperV wasn't greyed out anymore.

And Window Hyper V Server Started OK.

Thanks for your follow up and fix!

Just wanted to follow up with another thanks. 

Different ProLiant in my case, a ProLiant MicroServer Gen 10 Plus V2. 

Had to default the BIOS, then select the 'Virtualisation - Max Performance' profile. The virtualization options were still greyed out but after doing this, it was available to Windows. 

Many thanks !

Hello, 

I had the same issue with HPE proliant DL360 GEN 11. I had to disable Intel TXT support in the Intel security option.

after that all is working.
