Re: [libvirt] [PATCH 0/3 for 3.2.0] Fix host-model CPU with non-migratable features

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.
