VMware vSphere

Is there somewhere a simple overview what are the things that are nessecary to run a vm with vtpm?
I currentliy do not understand what to do/ to have beside the native key provider configured or the vcenter/exi at the lastes versions.

Thanks for input!

Its fairly straightforward like you're thinking. If you added the Native Key Provider to VCSA and it shows backed up and active then you add the TPM option to the VM.  It shouldn't complain about TPM 2.0 unless you are trying to setup TPM on the ESXi host, not a requirement for vTPM and the VM's. You covered the ESXi host is in a cluster which is a requirement.

Thank you  
Yes the VM is on one of the ESXi of a cluster.
Seems I do something wrong.

Native Key Provider is backed up an active:

Next I create a new VM with that settings:

After that I try to add the vTPM via the "new pci device" dialogue and get the error:

I have absolutely no clue what I do wrong.
Do i need other settings for the VM?
Does my vcenter need some more configuration I am not aware of?
Do need my hosts something that is missing?

You can uncheck this option during configuration
