I am trying to get TPM passthrough to a Windows VM, and am having some problems. My system is running 14.1-RELEASE, and I am using the latest version of /sysutils/vm-bhyve-devel to manage the VMs. I have configured the TPM to load in boot.conf and added the device hints per the
tpm() man page. It appears to be working and showing up as /dev/tpm0.

The computer is a Dell Optiplex 3060 with an i7 8700. Running
but also returns several messages of:
