Hi,<br><br>I want to use the vTPM in a qemu Windows image. Unfortunately, it didn't work.<br>First, the equipment:<br>TPM 2.0 hardware<br>CentOS 7.2<br>Qemu v2.10.2<br>SeaBIOS 1.11.0<br>libtpm and so on<br><br>My host is centos 7.2 with the TPM 2.0 hardware and qemu v2.10.2.<br>I
 make the libtpm and seabios with ./configure, make and so on. I checked
 seabios with make menuconfig the TPM setting. It is enabled tpm by 
default.<br>Eventually, all works without errors. <br><br>I start the Widnows 10 image with:<br>qemu-system-x86_64
 -display sdl -enable-kvm -m 2048 -boot d -bios bios.bin -boot menu=on 
-tpmdev 
cuse-tpm,id=tpm0,cancel-path=/dev/null,type=passthrough,path=/dev/tpm0&nbsp; 
-device tpm-tis,tpmdev=tpm0 win10.img <br><br><div>First it looks all 
fine. Windows 10 booted up but the vTPM was recognized as TPM 1.2 
instead of TPM 2.0 in device manager. I open the tpm Manager with 
tpm.msc but get error with No compatible TPM found.</div><div>If I use vTPM in a qemu linux image, everything gose well. <br></div><br>So, what could be the problem?<br>Thanks
