I think you are correct, the logs capture will fail too.

I'll leave it to Ian to suggest a solution since it will no doubt
involve some tcl plumbing (I'd be inclined to record 'hosts which are
actually guests' somewhere and have the infra clean them up
automatically after doing leak check and log collection).

/var/core is created by ts-host-install. I think the tail end of the
function sub in there which does that and populates /etc/sysctl.conf
and /etc/security/limits.d/coredumps.conf should be refactored probably
to be alongside the osstest-confirm-booted thing which IIRC you are
already going to refactor in the next version.

I was thinking more along the lines of creating Osstest/PDU/guest.pm
with the appropriate methods calling out to toolstack($l0)->foo, setting
$ho->{Power} = 'guest $l1guestname' somewhere and allowing
power_cycle_host_setup to do it's thing.

Ian.
