This has failed in everyone of a couple of dozen runs since the end of
August.

30019 was OK, so was 30032 but from 30050 onwards it is consistently
failing.

Failure is:
2014-09-23 05:39:03 Z guest debian.guest.osstest 5a:36:0e:94:00:07 22 
link/ip/tcp: waiting 40s...
2014-09-23 05:39:03 Z guest debian.guest.osstest 5a:36:0e:94:00:07 22 
link/ip/tcp: no active lease (waiting) ...
...
2014-09-23 05:39:44 Z FAILURE: guest debian.guest.osstest 5a:36:0e:94:00:07 22 
link/ip/tcp: wait timed out: no active lease.
failure: guest debian.guest.osstest 5a:36:0e:94:00:07 22 link/ip/tcp: wait 
timed out: no active lease.

Guest console logs are empty, host console log is uninteresting. The
xenstore dump shows that none of the devices are connected, all of which
suggests an early crash of some sort.

Baseline was f1bd473f aka v3.17-rc2-42-gf1bd473 and this is b0e2a55c6536
aka v3.17-rc6-7-gb0e2a55

Perhaps more interestingly the first failure in 30050 was 
fd5984d7c8e aka v3.17-rc2-227-gfd5984d, which is a much smaller range.

Nothing in the log (below) looks terribly exciting to me and there's not
a lot to go on. Anyone got any ideas?

Ian.
