Yes, a year old.

Furthermore, Justin tells me it carries a lot downstream patches.

It has its own machine type.  So this report may not indicate any 
problem with upstream.

Still, I feel we have a potential problem here.  We identify 
guest-visible attributes just by review; we're sure to miss something 
here and there.  Unlike ordinary bugs, compatibility problems only show 
up later and are much harder to fix.

Second, we don't do any tests in this area that I'm aware of.  Lucas, 
what would it take (thanks, you're most kind) to test multiple qemus in 
a single run?

We can have a script that runs lspci -vvvvvvvvvvvvvvvvvvv, x86info, and 
other interesting stuff and compare the results, and also system tests 
that boot a guest on multiple qemus (with the same -M and different -M) 
and see if things work.

We can probably continue on email, I don't see a real need for a call 
for this topic.
