Obviously, this probe would have to be tolerant of qemu not existing, but erroring out earlier than runtime might help people build correctly since this seems to be a recurring question on the list. And it must not break on RHEL 5, where qemu is old enough to not require yajl and where yajl is not available by default. -- Eric Blake eblake@xxxxxxxxxx +1-919-301-3266 Libvirt virtualization library http://libvirt.org
