qemu - win11: this PC can't run Windows 11

When trying to execute the setup the setup stops after selecting the os type with the following result:

"this PC doesn't meet the minimum system requirements to install this version of windows. For more information visit ..."

What is wrong, My pc is up to date and Windows has enough memory?

So first of all win11 has 3 major system requirements

• 4GB RAM
• Secure boot
• TPM-device

The requirement of your hypersisor is qemu version 4. It is installed with Ubuntu 20.04.

Secure Boot

We do need a secure "bios", which is an uefi system. Using "Virtual machine Manager" you do only have one chance to set this setting up. In the last step 5 you are asked, if you want to do some additional modifications to your machine. Set that hook. Once the machine is created, you won't have an easy chance to change that!

• got to the tab Overview
• Firmware change the default bios to : UEFI ... .secboot.fd

TPM device

The tpm thingy is a key management unit required by windows for security stuff.

If you not have installed swtpm yet, you have to install that on your machine.

https://launchpad.net/~smoser/+archive/ubuntu/swtpm
sudo add-apt-repository ppa:smoser/swtpm
sudo apt-get update
sudo apt-get install swtpm-tools swtpm

Change the permission of that folder if necessary

sudo chown -R tss:root /var/lib/swtpm-localca

The tss user is used by qemu. In this folder will be the certificates.

Once installed, add the TPM-device to your machine. In the configuration window of the machine choose:

- [Add Hardware]
- TPM
  - `Model`:`CRB`
  - `Backend`:`Emulated device`
  - `Version`:`2.0`

With a bit of luck, you should now be able to pass the magical win11 install barrier.
