For x86, this is done by reading qom-list-properties for max-x86_64-cpu and manually filtering out everthing that does not look like a feature name, as well as parsing target/i386/cpu.c for cpu models. This is a flawed, tedious and error-prone procedure. Ideally, qemu and libvirt would query a common source for cpu feature and model related information. Meanwhile, converting this information into an easier to parse format would help libvirt a lot. This patch series converts the cpu feature information present in target/i386/cpu.c (`feature_word_info`) into an xml file and adds a script to generate the c code from this xml. A patch set to convert the cpu model data (`builtin_x86_defs`) in the same way will follow.
