as soon as i change and after i run virsh:
virsh # net-define /etc/libvirt/qemu/networks/default.xml

it changes to:

# cat /etc/libvirt/qemu/networks/default.xml
  <forward mode='nat'/>
  <bridge name='virbr1' stp='on' forwardDelay='0' />
  <ip address='' netmask=''>
      <range start='' end='' />

and guest machine has no connectivity.
any ideas? is there something else i could try?
