[Bug 668043] [NEW] libvirt default network doesn't start, iptables errors, bad rules

[Thomas Monzie]

Public bug reported:

On ubuntu server 10.10 x64, using libvirt-bin 0.8.3-1ubuntu14

With virt-manager on a workstation (ubuntu 10.10 x64 desktop), connected
via ssh, trying to start default network  :

Traceback (most recent call last):
  File "/usr/share/virt-manager/virtManager/host.py", line 401, in start_network
    net.start()
  File "/usr/share/virt-manager/virtManager/network.py", line 97, in start
    self.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?).

After adding the rule,
sudo /sbin/iptables --table filter -A INPUT --in-interface virbr0 --protocol udp --destination-port 69 --jump ACCEPT

I get the following error (with virsh) :
sudo virsh net-start default
erreur : Impossible de démarrer le réseau default
erreur : internal error '/sbin/iptables --table mangle --delete POSTROUTING --out-interface virbr0 --protocol udp --destination-port 68 --jump CHECKSUM --checksum-fill' exited with non-zero status 2 and signal 0: iptables v1.4.4: unknown option `--checksum-fill'
Try `iptables -h' or 'iptables --help' for more information.
