I ran a bunch more in this no-apicv configuration, the logs are at
http://logs.test-lab.xenproject.org/osstest/logs/<NNNN>:

Flight	Host	Failed at
58190	fiano0	ts-guest-stop
58198	fiano0	ts-guest-stop
58203	fiano0	ts-windows-install
58208	fiano0	ts-guest-stop
58210	fiano1	ts-guest-stop
58214	fiano1	ts-guest-stop
58217	fiano1	ts-guest-stop

I think that's not sufficient data to draw a conclusion, since there was
always a small background failure rate. I'm going to run another half
dozen (3 on each).

NB the build artefacts from 57852 got garbage collected, so 58190
rebuilt them all (from the same versions) and those were used for the
other flights. I think this is unlikely to have made any difference.

I'm also going to run some on another pair of hosts without no-apicv. I
chose elbling[01] since according to
http://logs.test-lab.xenproject.org/osstest/results/history.test-amd64-amd64-xl-qemuu-win7-amd64.html it has been used a few times on various branches and hasn't so far failed a ts-windows-install. It looks to have the same set of advanced features as fiano*:
