[Bug 930962] Re: dhcp3-server reports many bad udp checksums to syslog using virtio NIC
I'd be ok with adding a /usr/share/lxc/hooks/network-bootpc-checksum script which does the iptables add, and having the debian template add that to lxc.hook.pre-start. However, in that hook script we'd want to avoid having one rule added per container start. What's the cleanest and most robust way to detect if the rule has already been inserted? We can do a iptables -t mangle -L and look for CHECKSUM udp -- anywhere anywhere udp dpt:bootpc CHECKSUM fill but that feels fragile.

[Bug 930962] Re: dhcp3-server reports many bad udp checksums to syslog using virtio NIC
This issue also affects the debian LXC template in Ubuntu (lxc 1.0.0~alpha1-0ubuntu11). If I create a Debian jessie container on Ubuntu Saucy, then the container cannot DHCP. Workaround: sudo iptables -t mangle -A POSTROUTING -o lxcbr0 -p udp --dport bootpc -j CHECKSUM --checksum-fill It looks like the Debian bug is http://bugs.debian.org/cgi- bin/bugreport.cgi?bug=717217 Is there any way a workaround could be applied to lxc in Ubuntu - perhaps something specific to the Debian template?

Recent kernel changes are now causing this issue to appear in LXC containers too where the libvirt mangle rule doesn't help at all.
