It's not been as long as ten days, the commit was the 14th. But yes we
need to know what is going on here ASAP -- Dario please can you take a
look.

It's an odd one -- the logs seem to show the guest has started but the
patch in question would (or should!) cause an early error return during
build. It's possible that the recent test system outage has caused the
bisector to get confused but it has fingered this changeset at least
twice now.

The bisector really should try and pull out S-o-b's et al from the
offending commit and add appropriate CCs. There's also something of an
expectation that developers will keep an eye on the test system results
after a patch of theirs has been expected though.
