Question: What is the value to provide an *empty* = HSTI table?

IMHO, If the goal is to perform some security check, I think we need provid= e a *real* HSTI table.

HSTI is very vendor-specifi= c and depends on features that a vendor supports. Looking at
the = HSTI spec a lot of the bits don't make sense for virtual machines. Some= feature depends on
hardware configuration and this check is a du= mmy in a virtual environment.

So, the main goal is t= o pass Microsoft SVVP with OVMF+QEMU.
