Windows 11 Pro as a VM in Ubuntu

Is anyone using Windows 11 Pro as a VM in Ubuntu? For me, it said the system does not meet the requirements. Is it because I tried to create a VM in Ubuntu (VirtualBox 6.1)? Is there any policy that says no VM in Ubuntu? I tried to use a portable SSD to keep the VDI file.

PS: I had a working Windows 11 on this PC before.

I'm not a VBOX user at the moment, I run it in QEMU/KVM on my Linux machine. But there is a tweak that works anywhere.
Is this happening during setup?
You should mount the VBoxGuestAdditions.iso (in the VM) where you'll find the windows11-bypass.reg to apply in the PE setup environment and then retry the install.

VirtualBox 6.1.xx does not provide TPM or Secure Boot emulation, so those factors alone are sufficient to prevent Windows 11 from installing. You need to adapt the usual hardware work arounds to the Windows ISO.

You can install without TPM, the provided reg entry bypasses the checks. This is provided in VirtualBox 6 additions which has no TPM and it's even provided in VirtualBox 7 additions which has a TPM. The point being, a VM doesn't necessarily need a TPM or a user might not want it.

Will try. Thanks :)

Yes, while trying to run the setup. I could get only up to selecting the language.

@Hopachi,

Sorry, but VirtualBox Guest Additions do not provide TPM/Secure Boot facilities in either Version 6.1 or 7.0 In 7.0 TPM and Secure Boot are provided through the initial VM installation via options available in the installation setup. Guest Additions are only installable after installation of an OS, for obvious reasons - There has to be a working Guest VM to install them in.

@LeLibran
True for Win11 default requirements. A TPM is needed but can be bypassed.

See my first post.
You misunderstood my wrong wording there in the my second post: VirtualBox 7 does provide a TPM:

NOT the additions themselves indeed. The additions ISO provide a (file) way to bypass the TPM requirement entirely.
And yes, you need the additions on an installed OS BUT the additions ISO is useful to add during setup. I've already done this.

You have to think outside the box with these installs. If you look carefully on the ISO, the additions ISO provides more than just some software to run on the installed OS.

See this:
(first two posts)

There are a lot of tutorials that show how to create the reg entries manually during setup, Shift+F10. But all that can be done faster if you just add the additions ISO in a secondary CD/DVD drive in the VM during setup and run/apply the reg file.

TPM emulation (package swtpm) usually works on Linux Hosts -- I don't bother with VBOX but use KVM/QEMU. You can always set the CPU topography to "Hypervisor default" which passes the Ms cpu test.

For using sec boot in a VM on a Linux host using KVM/QEMU install package OVMF.

I'm running Canary build W11 Pro on a laptop with an old i5 CPU which in Native mode fails W11 CPU test. As a VM on KVM/QEMU - works perfectly.




More details -- this is for Debian and similar distros (Arch Linux, Ubuntu etc).

Tried this, and now the error is gone :)
