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.
I have a question about TPM hardware.
Fedora 34 running as an image in a Vmware Player VM on a Windows 10 host
reports that I don't have a TPM chip, and with Windows 10 running in a
Virtualbox (both these VM' are the free versions of the VM's) VM on the
same Windows 10 host when I try to update the image to Windows 11 it
says the environment does not meet the install requirements. Vmware
Player doesn't support UEFI but Virtualbox does and is active in the VM
images. If I try upgrade the native Windows 10 host Windows 11 says it
can install on my hardware. The Bios indicates that I have activated
fTPM in my AMD Rizen cpu which Windows 11 seems to be finding, are the
VM's suppressing the TPM functionality because I need to buy the
commercial versions that allow a TPM to be added to the VM's as a
device, or is Windows 11 and Fedora 34 not looking for the hardware the
right way when running in a VM?
regards,
Steve
