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

[Bill Burman]

I installed this patch late last night, and got the error

error: 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'

I also confirmed that the interface was not started. I tried more than
once, just to be sure.

However, I tried again this morning, and it worked, the interface was
created, and no errors were reported.

The host has been running without reboot since last night, and before
the patch was applied, no other updates have been applied.

I can see that apparmor did a "profile_replace" on libvirt some time
after it was started, I don't know much about apparmor, but is it
possible this should have been reloaded or something? This is the only
thing I can see in my logs that might have changed between it not
working and now, when it does.
