XPS 8950, Virtualization Support in BIOS?
Good morning,
I am trying to figure out if it's possible to enable/disable virtualization support in the BIOS? I know the manual says it is possible but my BIOS looks nothing like the manual, and it looks nothing the BIOS in my XPS 9530 laptop either. It was just updated so it's on the latest version, 1.22(?)
Is there another super secret BIOS that I can install to get that?
I am trying to VMWare player or workstation in order to use Cisco CML and I'd rather not do it on my laptop.
Why does Dell want to charge me $99 just to ask a question?
Thanks,
Leonard

Version of Windows?
Don't have XPS 8950, so I can't give direct info, but if there are tabs in BIOS setup, did you look at all of them? The manual says virtualization is enabled by default.
Click Start>Run>msinfo32.exe and click OK. When that opens, click Summary at top left. Then scroll down to bottom of right pane to see what it says about virtualization....
Have you read this?

Thanks for the reply.
I have looked at all of the tabs and virtualization is nowhere to be found.
VM and hypervisor platforms are both off. Msinfo says virtualization based security is running.
Memory integrity in Core isolation is disabled.
I've found no place to disable Device Guard.
I've been thru dozens of threads on different platforms and they basically point to the same settings, all of which I have checked.

What about Secure Boot and TPM in BIOS?
Have you tried to enable Virtual Machine and Windows Hypervisor on the Windows Features screen?

I forgot to mention this is Windows 11 Home. Both Secure Boot and TPM are enabled in the BIOS. I disabled Secure Boot then installed Virtual Machine and Hypervisor in different combinations and nothing worked.
What's odd is this worked before Microsoft blue screened this machine with last months update which caused me to reinstall Windows and before the latest BIOS update.
Thanks for the ideas, really appreciate the help.

Did all the drivers get installed after you reinstalled Windows, especially the Intel Chipset and Intel Management Engine?
Make sure the latest Chipset is installed before you install the Management Engine....

I installed both of them and it didn't help. I have an old XPS 8770 that I had Ubuntu running on and it has virtualization support in the BIOS, so I put Win10 and VMware Player on it and CML works fine, and I can access it from my 8950 so that's a win/win. Now I just need to get WSL2 running so I get Ubuntu back.
I really wish I knew what made that stop working, it's probably going to bug me for a few days but I'll get over it.
Thank you very much for your help, I really do appreciate it.

I pinged my Dell contacts about this issue. I'll post here, if I hear anything useful...
FWIW, I suppose you could downgrade BIOS back to a prior version where thing worked properly. Make sure BIOS downgrade is enabled in BIOS setup, and pay attention to any warnings on the BIOS 1.22.0 support page about how far back you may be able to go, especially since you will likely lose security fixes.
If you do downgrade, you should immediately go into BIOS setup again and disable UEFI Capsule Updates. Otherwise, Windows Update could force-install 1.22.0 again without permission or warnings. And if SupportAssist is running on this PC, you may want to completely disable it so it also won't update BIOS (or any other drivers, etc).
