Description of problem:

it appears impossible to run libvirt daemon and dnsmasq at the same time.


Version-Release number of selected component (if applicable):

libvirt-0.8.3-2.fc14.x86_64
dnsmasq-2.52-1.fc13.x86_64
kernel version 2.6.35.11-83.fc14.x86_64

How reproducible:

# sudo service dnsmasq start
# sudo virsh net-start default

Steps to Reproduce:

see above
  
Actual results:

error: Failed to start network default
error: internal error '/sbin/iptables --table filter --delete INPUT --in-interface virbr0 --protocol udp --destination-port 69 --jump ACCEPT' exited with non-zero status 1 and signal 0: iptables: Bad rule (does a matching rule exist in that chain?).

Expected results:

both services start correctly

Additional info:

if i stop dnsmasq and then issue the command "sudo virsh net-start default" it starts correctly. 

if i start the default network usuing the "sudo virsh net-start default" command and then try to start dnsmasq service, i get this:

# sudo service dnsmasq start
Starting dnsmasq: 
dnsmasq: failed to create listening socket: Address already in use
