Virtualization in Windows and DCS?

[SharpeXB]

In an attempt to stop these crashes:

HYPERVISOR_ERROR bug check value of 0x00020001. I’m going to try disabling Intel(VMX) Virtualization Technology in my BIOS

It appears that Virtualization is not enabled by default in Windows 11 Home. Not sure about Pro

https://support.microsoft.com/en-us/windows/enable-virtualization-on-windows-c5578302-6e43-4b4b-a449-8ced115f58e1

I’m speculating that having this enabled in the BIOS but not in Windows might be the source of the problem. Having both enabled still results in the crash though.

Question: Is this feature used or necessary to run DCS? Looking at a description of what it does:

“Virtualization lets your Windows device emulate a different operating system, like Android or Linux. Enabling virtualization gives you access to a larger library of apps to use and install on your device”

My guess is no. Especially since it’s not a default feature.

I have that one particular option disabled in BIOS too. Other virtualisation options in BIOS however are needed in case you want to enable VBS (virtualisation based security) in Windows, which is highly recommended.

This is what I disabled

I tried all this with no success. This person must be using Pro because the Hyper-V feature is available. I had tried enabling Virtual Machine Platform instead.

I never had that error before. I'll reboot into BIOS and see exactly what I have disabled: I'll try to post a picture here.

EDIT:
This is what it looks like for me. Obviously I have an AMD system so things look a bit different and have different names, but I believe they are the same:

SVM is needed for VBS to work in Windows (I have W11 Pro), so that's enabled.
SR-IOV is needed for virtual machines, which I don't need and is thus disabled.
Everything else related to virtualisation is left on auto/default.

Hello everyone.
So, do I need to disable VMX (in the BIOS) or do I need to enable VMX?
What's best?

Woah this may have caused an instant CTD in DCS

DCS still crashed regardless. I think turning this off in the BIOS prevents those Hypervisor crashes though. 

Be careful. When I disable that in the BIOS my PIN won’t work on the PC and I need to use my password.

With this disabled in the BIOS my PIN code won’t function on the PC
