So far we only test CPUID -> CPU def conversion on artificial CPUID data computed from another CPU def. This patch adds the infrastructure to test this conversion on real data gathered from a host CPU and two helper scripts for adding new test data: - cpu-gather.sh runs cpuid tool and qemu-system-x86_64 to get CPUID data from the host CPU; this is what users can be asked to run if they run into an issue with host CPU detection in libvirt - cpu-parse.sh takes the data generated by cpu-gather.sh and creates data files for CPU detection tests The CPUID data queried from QEMU will eventually switch to the format used by query-host-cpu QMP command once QEMU implements it. Until then we just spawn QEMU with -cpu host and query the guest CPU in QOM. They should both provide the same CPUID results, but query-host-cpu does not require any guest CPU to be created by QEMU.
