See https://lists.ozlabs.org/pipermail/lguest/2013-May/002001.html .
Nobody cared enough to fix it. I cared enough to figure it all out. But
I didn't understand much of the possible solutions that where suggested
three years ago.

I'm certain I still ran into this issue with the microcode loader in
the beginning of this year, so that was probably with a v4.4 based
guest.
