How would I change this BIOS issue to allow Hyper-V on a server?

Medium Priority

Last Modified: 2020-06-07
I recently installed Windows Server 2019 Standard on a Dell PowerEdge 2900 that used to run SBS 2008. This is NOT my current production server which is a new Dell T430 which is easily capable of running Hyper-V.

It may be possible that the old Dell just isn't up to the task. I am trying to use it as a "sandbox" to run VMs and restores.

Restart server and enter BIOS
In the BIOS, under CPU Information, and make sure Virtualization Technology is enabled.
Save change and exit

Thanks,

I did that. Very easy. Then I got this error message, which I doubt I can work around. Not sure adding a new processor to an 8 yo server makes sense.

Try using DISM to enable the feature
Dism /online /enable-feature /featurename:microsoft-Hyper-V -All

Where is that located?

You can run the command at the prompt, run as administrator.

That worked great. Updated the BIOS. Hyper-V now has a checkbox next to it as though it is installed. Rebooted the server. But, I can't find the Hyper-V icon to open Hyper-V. I think we are getting closer though.

I checked on my actual production server, which runs Hyper-V. ---- Hyper-V manager was listed under tools in the Server Manager. It is not there on the Dell 2900.

At the best ypu have a Xeon 5400 CPU but according to https://social.technet.microsoft.com/wiki/contents/articles/1401.hyper-v-list-of-slat-capable-cpus-for-hosts.aspx you need a 5500 or later CPU to have SLAT.

Make sure the server is compatible I using Securable from Steve Gibson's site.  https://www.grc.com/securable.htm  It will tell you things like VT is turned off as Iamthecreator OM advised.
I would then uninstall the Hyper-V role and reinstall.

Thanks all. I am downloading the Hyper-V-2019. If this doesn't work, I will back track as Andy and Rob suggested.

I think I will wait on the download. Looks like the entire Windows.

@Andy, may be worth doing 2012 since I need Hyper-V. But, as a very wise EE advisor once said, may as well use 2019 to learn the latest -- of course, it is a risk-benefit thing.

Nothing too quick.

The Hyper-V download has no GUI. You have to use RSAT tools to manage from another computer and initial set up is from a command line.  Also, as of Jan 2020, server 212 is no longer supported.  Better to go with 2019.

The big issue is I want to be able to "restore" VMs to a separate server than the production server to spin them up and test them. Need Hyper-V for that. Windows Server 2016 Standard would mimic the production server.

2019 and 2016 are fine

Since the MS article says "Other than that, the main difference in hardware is that second-level address translation (SLAT) is now required instead of recommended." I fear 2019 and 2016 are not fine.

OK, not fine in that sense.
Easy to test if your server supports SLAT

No Dell 2900 supports SLAT, they are Xeon 5000 - 5400 and SLAT wasn't introduced until Xeon 5500.

Ebay has tons of servers you can buy for $200 that will have an appropriate processor with SLAT.  I don't THINK 2016 requires SLAT, but 2019 definitely does.

Commented:
So, I have been lucky to have some of the best experts on EE helping with this question. I am confused though as far as Hyper-V being compatible with 2016. If I am reading correctly, some say it is and some say it isn't.

I am currently on 2019. I don't need to be. I have no problem installing 2016, but only if I know that Hyper-V will work after.

The issue is your server, as andyalder pointed out, is not SLAT compatible, so you cannot install Server (Hyper-V) 2016 or 2019.  SLAT is not a requirement for Server 2012 Hyper-V and previous versions.

If it's just a sandbox you can use a PC processor, all i series processors are SLAT and VT compatible, though sometimes you have driver issues with PC NICs and server O/S, or other hardware.

Commented:
Thanks. I thought of that. But, the PCs I have that could be used have i7s, but they the PCs are getting a bit old.

Try one.  If it works OK, i.e. drivers are compatible add RAM

Not as old as your server since any i7 PC does support SLAT.

The Lenovos were bought in January of 2011. The server was purchased on 8/29/2008. It is running right beside me.
