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.

LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
