This is indeed what seems to be causing the problem.  Note that we're
seeing (a worrying number of) retries in some of the earlier (and
successful) transfers.

What kind of bridge is being used here? (virbr0 -the bridge created by
virsh-, br0, ?).  Can you please paste the characteristics of the bridge
(by running something like "cd /sys/class/net/virbr0/bridge; for f in
`ls *`; do echo -n "$f "; cat $f; done).

As described on https://bugs.launchpad.net/maas/+bug/1155556, the
default timeout behavior might be the problem here.  Can you try
changing the RemoteOriginReadSession class in
/usr/share/pyshared/tftp/bootstrap.py: change the timeout = (1, 1, 1, 1,
1, 1) to  timeout = (1, 3, 7). and then restart the TFTP server?
