What is TPM?

TPM - Trusted Platform Module. It's a new age tech for security on the hardware and software levels. Don't ask me about how it works because I don't know. laugh


Is TPM required for Windows 11?

So, the answer is yes. Pretty sure, yes! It's a required module to install new windows 11 OS on any device. But it creates some consequences. Like, older CPUs are not supporting this new tech. TPM is also mandatory for windows 11 virtual machines. So, users have to enable TPM on the hypervisor to install the windows 11 OS. Most hypervisors support TPM.


How to install TPM on Ubuntu KVM?

The first step is, Install the below repo into Ubuntu by editing /etc/apt/sources.list the file. Please make sure the repo is as per your ubuntu version. Like this one is for Ubuntu Focal - 20.XX.X LTS. You can check your Ubuntu version by using lsb_release -a  the command.

deb [trusted=yes] focal main

Now, update the local repository catch for new updates by using the below command.

sudo apt update

Now, install TPM directly from the repo by following the below command.

sudo apt install swtpm-tools

swtpm --version

To install TPM from source code, you need to download its source code from the git repository and then compile it on the local machine and need to make deb an installation file. But it's required some skills related to source code compilation and all. That's it related to TPM installation.

The next step is, Enable secure-boot/UEFI on KVM. (This step is optional because when you install Virtual Machine Manager on your ubuntu, it will by default install secure boot/UEFI related libs to enable it.)

sudo apt install ovmf

Now, Open your Virtual Machine Manager for the final Windows 11 OS installation. Follow all steps as you know. But, wait just before clicking on the Finish button.
