However, qemu_capabilities depends on qemu_monitor, so that would introduce a circular dependency and I'm not sure trying to break it up is worth the effort. So if anyone fells like weighing in on the subject, or provide alternative suggestions, I'm all ears. -- Andrea Bolognani / Red Hat / Virtualization -- libvir-list mailing list libvir-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/libvir-list
