http://logs.test-lab.xenproject.org/osstest/results/history.test-amd64-amd64-xl-qemuu-win7-amd64.xen-unstable.html shows some migration failures too (in a batch though, not spread out).

Wouldn't the migration issue be potentially blocked by the install one?

All the flights in the new colo seem to have been on fiano[01].

But having looked at the page again the early success was all on fiano0
while the later failures were all on fiano1.

fiano[01] are supposedly identical hardware.

This might be simply explained by osstest's stickiness for jobs on hosts
where they are failing. I'll run a few adhoc jobs on fiano0 using 57852
as a template so we can see if that's the case.
