Re: [libvirt PATCH v2 2/3] cpu_map: Add script to sync from QEMU i386 cpu models

This script is intended to help in synchronizing i386 QEMU cpu model definitions with libvirt. As the QEMU cpu model definitions are post processed by QEMU and not meant to be consumed by third parties directly, parsing this information is imperfect. Additionally, the libvirt models contain information that cannot be generated from the QEMU data, preventing fully automated usage. The output should nevertheless be helpful for a human in determining potentially interesting changes.
