SMART test script tracebacks when run on a KVM instance

[Jeff Lane ]

This is the result of running the SMART script on a KVM instance of Ubuntu 14.04.

Traceback (most recent call last):

this should be handled a bit better.

Reopening - this has now been seen on bare metal as well.

When the selftest is launched manually from CLI, this is the result:

ubuntu@slight-square:~$ sudo smartctl -t short /dev/sda
smartctl 6.2 2013-07-26 r3841 [x86_64-linux-3.13.0-35-generic] (local build)

Short offline self test failed [unsupported scsi opcode]

the script already looks for stdout and stderr, as well as returning the result code, but I wonder if smartctl is returning a 0 here...
