I configured a key providor, it shows active. I don't see any issues under the Constraints tab.
When I try to create a new VM and add device, the option to add a TPM is there now but when I click add, it shows in the list of hardware devices but at the top theres an error: The maximum number of devices of this type has been reached.
---------------------------------------
NM, I didn't realize it added the TPM automatically now so it was fussing at me for trying to add a second.
