This series fixes a regression in libvirt which would break domains with a CPU defined as, for example:
<cpu mode='host-model'> <feature name='invtsc' policy='require'/> </cpu>
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
