The pass/fail status of the log capture is not very interesting,
because the log capture wants to keep try other captures even if some
of them fail.  So it traps errors.

And indeed:

This shows that my guest.pm is completely broken.  sshuho needs
exporting from TestSupport.  After that is fixed there are probably
other bugs.

And this log message is supposed to have some actual information.
I don't know what is wrong here.  I would start by adding some prints
(using Data::Dumper) to guest.pm::new and guest.pm::fetch_logs.
