The way I do it is to use a qemu patch

https://lore.kernel.org/qemu-devel/20231004184219.6594-1-jejb@linux.ibm.com/

which allows qemu to connect to the mssim (or ibmswtpm2) TPM over an
inet socket which means I can execute TPM commands from the host (like
resetting the TPM) as well as the guest and snoop the TPM traffic.
