When hyperv code generator for WMI classes identifies common properties, it needs to take into account array type as a distinct type, i.e string != string[]. This is the case where v1 of the Msvm_VirtualSystemSettingData has Notes property as string whereas v2 uses Notes[], therefore they have to be treated as different fields and cannot be placed in the "common" struct. ---
changes in v3: * add virBufferCheckError before calling virBufferContentAndReset.

Extra whitespace. ACK. I fixed both problems and pushed the result, thanks. -- Matthias Bolte http://photron.blogspot.com
