[libvirt] libvirtd cpu usage

hi there i'm playing on debian lenny with kvm-66/libvirt-0.4.2 . if i run top, i see libvirtd is top cpu consumer. if i connect with strace to libvirtd, i see a thousand times this message: poll([{fd=3, events=POLLIN}, {fd=6, events=POLLIN|POLLERR|POLLHUP}, {fd=7, events=POLLIN|POLLERR|POLLHUP}, {fd=8, events=POLLIN}, {fd=13, events=POLLIN|POLLERR|POLLHUP, revents=POLLHUP}, {fd=15, events=POLLIN|POLLERR|POLLHUP, revents=POLLHUP}, {fd=17, events=POLLIN|POLLERR|POLLHUP}, {fd=19, events=POLLIN|POLLERR|POLLHUP}], 8, -1) = 2 if i stop libvirtd and start the guest myself on cli, the guest is much faster. - Thomas
