I think osstest's machines don't get microcode updates.  I'm no expert
on x86 microcode, but my understanding is:

Microcode updates (i) have to be loaded dynamically at boot time and
(ii) are regarded as a non-free package by Debian.

We could arrange to install the non-free microcode package.  I haven't
looked into it but I would expect that to automatically arrange to
load the microcode for native boots.  It IMO ought to do the same for
non-native boots but I wouldn't rely on that being the case.

Ian.
