What do you do to cause trigger the high CPU usage ? Does it occurr the moment you start libvirtd ? Or only when you start a VM ? Or only when you shutdown a VM ? Or something else altogether... The output of 'lsof -p' on the libvirtd process might be helpful. You might also try running with --verbose and LIBVIRT_DEBUG=1 envirnoment variable set and capturing the output
