VirtualBox 7.0 BETA2 Ubuntu 22.04 Guest, Windows 10 host TPM2 Error

[GilW]

Hello,

I'm trying to use TPM2 on Windows 10 host with Ubuntu 22.04 Guest.
setting->System->Motherboard->TPM: v2.0

$ sudo dmesg | grep -i tpm

The error:

Thanks for the report, this should be fixed with the next Beta!

Thanks!

With BETA3 I can access the TPM from the Ubuntu 22.04 Guest.

But still getting an error message:
