Public bug reported:

I tested a devstack today with libvirt-lxc, and was unable to get a dhcp
address in cirros 0.3.2.

The reason is that cirros's udhcpc seems to ignore the response if it
doesn't have checksums.

the appropriate mangle rule would be written if /dev/vhost-net , but
with newer kernels this is also happening on the lxc network devices.

It seems the sane thing to do at this point is just to drop the
protection based on '/dev/vhost-net' presence.
