Here are some more which I propose to force push.  In each case I show
all the blocking tests mentioned in the osstest test report.

These are all FreeBSD migration tests.  These seem to be failing much
more often in the new colo.  As I say I don't know why this is.  We
hope to fix it with the FreeBSD 10.1 update which Roger has submitted
and which is currently in the osstest self-push-gate.

In the general case they fail after a number of successful runs.  In
each case the symptom is that the guest simply doesn't come back onto
the network after the one of the migrations.  I double checked
  http://logs.test-lab.xenproject.org/osstest/logs/50391/test-amd64-i386-freebsd10-amd64/info.html
and as with the earlier tests there doesn't seem to be any hints in
any of the logs.

These are all localhost migrations.  This rules out a problem with the
colo infrastructure dropping or not honouring gratuitous ARP or MAC
address migration, since the guest's MAC and IP address remain (from
the infrastructure's point of view) on the same switch port.
