Hi， I am sorry, I bothered you. Still vTPM 2.0 for win 10 problem， I downloaded the latest qemu source from git, the version is V3.0.50. I think this is the latest code of qemu upstream. I also downloaded seabios upstream and bulid it with tpm2 support. Unfortunately, I tried both passthrough and emulator, and I didn’t get the expected results.
For emulator， I did it like this： #mkdir /tmp/mytpm2/ #chown tss:root /tmp/mytpm2 #swtpm_setup --tpmstate /tmp/mytpm2 --create-ek-cert --create-platform-cert --allow-signing --tpm2 #swtpm socket --tpmstate dir=/tmp/mytpm2 --ctrl type=unixio,path=/tmp/mytpm2/swtpm-sock --log level=20 --tpm2 No errors occurred, suggesting that the certificate was also generated successfully.Then I created a blank img file named win10.img，and install win10 virtual machine as follows： #qemu-system-x86_64 -display sdl -enable-kvm -cdrom win10.iso -serial stdio -m 2048 -boot d -bios bios.bin -boot menu=on -chardev socket,id=chrtpm,path=/tmp/mytpm2/swtpm-sock -tpmdev emulator,id=tpm0,chardev=chrtpm -device tpm-crb,tpmdev=tpm0 win10-ovmf.img Enter the system when the system is successfully installed，I found that the TPM 2.0 device was not found in the System Device Manager. If I replace -device tpm-crb with -device tpm-tis and reboot the system，The TPM device can be found in the device manager.But the vTPM 2.0 is recognized as vTPM 1.2. I also tried passthrough mode， The result is the same as emulator. So, what could be the problem? > -----原始邮件----- > 发件人: "Kevin O'Connor" <ke...@koconnor.net> > 发送时间: 2018-08-21 12:08:59 (星期二) > 收件人: "汤福" <tan...@gohighsec.com> > 抄送: seabios@seabios.org > 主题: Re: [SeaBIOS] vTPM 2.0 is recognized as vTPM 1.2 on the Win 10 virtual > machine with seabios > > On Mon, Aug 13, 2018 at 04:45:43PM +0800, 汤福 wrote: > > Hi, > > > > I want to use the vTPM in a qemu Windows image.
