Hi Salman,
under Fedora, the file to update is /etc/sysconfig/libvirtd, and uncomment the following line 
# LIBVIRTD_ARGS="--listen"
See : http://wiki.libvirt.org/page/Libvirt_daemon_is_not_listening_on_tcp_ports_although_configured_to

I'll try to fix the documentation today for Fedora/ CentOS instructions

Regards,
Razique
