[Pkg-libvirt-maintainers] Bug#607897: virt-manager fails to create virtual network

[Daniel Kauffman]

Package: virt-manager
Version: 0.8.4-8
Severity: important

Virt-manager fails to create virtual network. Guests start and run, but 
without networking.

Error displayed by virt-manager:

Error creating virtual network: 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?).

Details:

Traceback (most recent call last):
   File "/usr/share/virt-manager/virtManager/createnet.py", line 349, in 
finish
     self.conn.create_network(xml)
   File "/usr/share/virt-manager/virtManager/connection.py", line 730, 
in create_network
     net.create()
   File "/usr/lib/python2.6/dist-packages/libvirt.py", line 866, in create
     if ret == -1: raise libvirtError ('virNetworkCreate() failed', 
net=self)
libvirtError: 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?).

Additional information:

Iptables version is 1.4.8. Libvirt version is 0.8.3-5.

Local user running virt-manager is a member of the libvirt group.

Connection in virt-manager is qemu:///system

Let me know if additional information would be helpful.
