There's already something on list about l2 cache, see
https://www.redhat.com/archives/libvir-list/2017-September/msg00553.html
it adds 3 related variables. IIRC, the "hold up" is how best to describe
how to use it or provide the feature in such a way that it's
"understandable" for general consumption without making a "policy"
that
generates certain values based on expected usage/needs for the client.
