From the mail, it appears that a software TPM should solve the

a TPM is found. So, for those who have already tried version 11, has
any one of you
tried installing on an older laptop, and then adding a software TPM,
or is this impossible? --doug
As stated earlier, my system doesn´t have a hardware TPM, but adding a
software TPM in virt-manager was enough.

Three questions:
Background: I have Windows 10 on the computer, even tho there are no apps
on it--I only use Linux. There may someday be a need for Windows?
Q1: Could you install the win 11 and then add the TPM s/w, or must the TPM
be on the machine already.
Q2: If it must be on the machine already, do you install it from a previous
version of Windows, i.e., Win 10? If not then how?
Q3: Would you please direct me to the source of the TPM you installed?
Thank you--doug
The "software" TPM being talked about is more like TPM emulation. It can be added to
any VM via virt-manager on the "Hardware" screen and using the button in the lower left
to add hardware.
The TPM can be added to any VM. The one caveat is that the VM must have been created to
boot via UEFI and not BIOS. That option needs to be specified when the VM was created.
None of my motherboards have a TPM. So I use the emulation. However, if you're motherboard does
have a TPM, I believe there is an option when adding TPM to a VM to use "Pass Thru".
It isn't possible, AFAIK, to simply change a VM from BIOS to UEFI.
