From: Christian Ehrhardt <christian.ehrhardt(a)canonical.com&gt; Sadly some devices provide invalid VPD data even with fully updated firmware. Former hardning like 600f580d "PCI VPD: Skip fields with invalid values" have already helped for those to some extent. But if one happens to have such a device installed in the system, despite all other things working properly the log potentially flooded with messages like: internal error: The keyword is not comprised only of uppercase ASCII letters or digits internal error: A field data length violates the resource length boundary. The user can't do anything about it to change that, they will be there on any libvirt restart and potentially distract from other more important issues. Since the vpd decoding is implemented rather resilient (if parsing fails all goes on fine, the respective device just has no VPD data populated eventually) we can lower those from virReportError(VIR_ERR_INTERNAL_ERROR to just VIR_INFO. If needed for debugging people can set the level accordingly, but otherwise we would no more fill the logs with errors without a strong reason.
