[Bug 930962] Re: dhcp3-server reports many bad udp checksums to syslog using virtio NIC

[Robie Basak]

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? I wonder if the
template could arrange for an iptables inside the container to mangle
the incoming DHCP packet or something.
