[Joe Cropper <jwcroppe@xxxxxxxxxx>]

Public bug reported:

In the compute manager's 'retry' logic (i.e., handling
RescheduledException) in _build_and_run_instance, it has a catch-all
case for all exceptions and sets reason=str(e).  This works well in most
cases, but for cases in which lower level code may generate locale-
specific messages, it's possible to see the "UnicodeEncodeError: 'ascii'
codec can't encode character..." error, which ultimately masks the
message in the compute logs, etc.

It also means the instance won't be rescheduled as it fails with an
error similar to...

WARNING nova.compute.manager [req-7fe662b1-c947-4303-b43f-114fbdafe875
None] [instance: 333474eb-dd07-4e05-b920-787da0fd5b32] Unexpected build
failure, not rescheduling build.
