Hey,

I was able to reboot my machine and run some tests tonight. From my side, I am following the template in the following link: https://github.com/ohthehugemanatee/win10vm. Same company, same limitations - I am just skipping the networking part for now.

First, your command looks good:

ubuntu@ubuntu:~$ sudo qemu-system-x86_64 -nodefaults -S -display none -monitor stdio -tpmdev passthrough,id=tpm0,path=/dev/tpm0 -device tpm-tis,tpmdev=tpm0
QEMU 5.2.0 monitor - type 'help' for more information
(qemu)

For my VM, I do get past tpm (yey!), but I am stuck on this other issue. I am attaching the results of the commands bellow with LIBVIRT_DEBUG=1. Sorry, I am really just guessing that this is the debugging info needed.

ubuntu@ubuntu:~$ virsh start win10.2
error: Failed to start domain win10.2
error: Could not open TPM device /dev/tpm0: Permission denied

ubuntu@ubuntu:~$ sudo virsh start win10.2
error: failed to get domain 'win10.2'
