A very common cause of this problem is that a systemwide instance of
dnsmasq is already (erroneously) listening on the bridge created by
libvirt for the default network. I took your email as an oppurtunity to
write an entry in the new Troubleshooting section of the libvirt wiki.
It will explain to you how to solve your problem (*if* this is your
problem, of course :-).

 
http://wiki.libvirt.org/page/Virtual_network_%27default%27_has_not_been_started

If that ends up not being your problem, please reply to this message,
but sending the reply to libvirt-users at redhat.com (I also Cc'ed this
message there) rather than to libvir-list at redhat.com. (The former is the
official list for user questions about libvirt, whil libvir-list is
intended for for people discussing the code.)

The "default" network should already be there as part of the stock
install.

Laine, yeah, I'm missing this important reason.

Great, I want to tidy up a doc about this ago, it should be very helpful 
for a new guys.

this is not my problem, as i dont use dnsmasq.

below is my /var/log/libvirt/libvirtd.log

and currently output of "brctl show" is:
# brctl show
bridge name	bridge id		STP enabled	interfaces
pan0		8000.000000000000	no		
virbr0		8000.000000000000	yes		


so what is wrong with my system?

thanks,

You means you haven't a dnsmasq process is running before starting virtual
network 'default', right? I want to know a cmdline argument of the
dnsmasq
process by ps -ef|grep dnsmasq

If you manually stop virtual network 'default' and dnsmasq service then
restart 'default'
network, does it work for you? for instance:
% virsh net-destroy default

% service dnsmasq status
if your dnsmasq is still active then stop it, otherwise, please ignore the
following step:
% service dnsmasq stop

make sure you haven't any dnsmasq process is running by ps -ef|grep dnsmasq,
then
active 'default' network again:

% virsh net-start default
if the above step is failed, please give related logs and virsh output.

what's dnsmasq process with cmdline?
% ps -ef|grep dnsmasq
