Ah ok, I was using the isc-dhcp-server on a KVM guest to isc-dhcp-clinet on
another one.

But thought I also had been using the dnsmasq setup created by libvirt for Xen
dom0 to domU. Hm, wait, I may have seen something somewhere in all those links
and reports that mentioned libvirt having a quirk for that. Are you using
dnsmasq on your own or have libvirt in use?

(If libvirt does something it probably is the ipfilter based approach that is
mentioned in a few placec)

The handling should be the same on server or on desktop. But then, maybe network
manager is doing something when it sees the checksum errors. That would not be
happening on server.
