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 redhat com (I also Cc'ed this
message there) rather than to libvir-list 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.
