Hm, I did

kvm -tpm type=builtin,path=tpm.img -m 1G disk.img -vnc :1

with disk.img being a newly installed VM.  I installed trousers
and tpm-tools, tried loading the tpm, tpm_tis, tpm_infineon, and
some other modules, /dev/tpm was never created, and

  tpm_takeownership

continued to give me:

Tspi_Context_Connect failed: 0x00003011 - layer=tsp, code=0011 (17), Communication failure

Which kernel module should work with builtin?

thanks,
