Title:
_get_host_sysinfo_serial_os fails with different exceptions if the
machine-id file is not present or if it is empty
Status in OpenStack Compute (nova):
Fix Released
Bug description:
When the sysinfo_serial config parameter for the libvirt driver is set to
'os', the defined behavior is:
- return the value found in /etc/machine-id file or
- return an error if the file is not present.
There is an additional scenario where the file is present but it is empty
(https://bugs.launchpad.net/ubuntu/+source/nova/+bug/1413293) in that case we
want nova to behave as if the file was missed.
At the moment the missing file and an empty file return different exceptions:
- IOError for a missing file
- IndexError for an empty file
Both of these errors are too general and don't give a big help in debugging
the issue.
Please note that we do not want to fix the issue about a missing/empty
machine-id file, that is something related to a bad OS
installation/configuration or a bad image, the proposed fix is just to
keep nova behaves consistently and giving back to the user a more
clear and precise error.
