swtpm VS tpm2-tss-engine

Or you can just add a virtual tpm device in virt-manager while setting up the vm using swtpm. It seems to ha e packages on most major distro's.

If you want Windows 11 instead for whatever reason, swtpm can emulate a TPM chip for QEMU to use.

You can find the source of software TPM implementations which abide to the official spec such as: https://github.com/stefanberger/swtpm but that has no real bearings on the TPM used on real hardware

I install swtpm and in virt-manager add a TPM 2.0 emulated device and set the secure boot image before I install. This seems to work well enough.

I don't know either, but apparently Microsoft didn't guarantee that 'unsupported' systems would continue to receive system updates. I just use a QEMU VM and swtpm.

swtpm - a software Trusted Platform Module emulator and the ways of using it;

Seems there are two such projects for that:

Linux has several TPM emulators. This one is probably the most popular. But here's another for TPM 1.2 only. The main use-case is to emulate TPMs for use with Virtual Machine guests.

Other GitHub posts from previous versions seem to have the issue described here but maybe I missed something, https://github.com/stefanberger/swtpm/issues/572 I'm on an arch install and just installed it from pacman.
