Hello all,
Long-time bhyve-in-production user Jason Tubnor pointed out that a
recent Windows 11 update breaks the "lab mode" under which Windows 11
could be run without a TPM (Trusted Platform Module) chip via a
registry edit. Corvin has made significant progress with TPM
pass-through support but it only supports one VM associated with the
hardware TPM.
This 3-clause BSD-license software TPM project has existed but I have
never heard it brought up in the bhyve context, possibly because of
the available workaround:

Is anyone be willing to look into porting this to bhyve?
All the best,
Michael
Hello,
If anyone can take a look and merge these, it would be a start:
* libtpms https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=272972
* swtpm https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=272973
As I never read bhyve code before, I will start glancing it and trying
to figure out stuff from Corvin's previous PR enabling pass-through for
TPM. If anyone has any info to speed me up on this quest, please speak!
Thank you!
Regards,
meka
