This series fixes a regression in libvirt which would break domains with

Such domains would work just fine with libvirt <= 3.1.0 or QEMU < 2.9.0,
but they would be broken with current libvirt and QEMU >= 2.9.0.
This is because we started asking QEMU for CPU features supported by the
host CPU, by which we think all non-migratable features are not
supported because QEMU filters them out by default.
This series changes our code to properly detect even non-migratable
features, but still leaves the piece which relies on our cpu_map.xml to
filter them when someone asks for just <cpu mode='host-model'/>. Patches
which will use the data provided by QEMU instead of our static database
in cpu_map.xml will be sent soon, since they are not required to fix the
regression.

ACK series. I'll keep the bunny ears of shame handy, just in case. Jan
