[pve-devel] [PATCH storage v2 04/10] ovf: implement parsing the ostype

[Dominik Csapak]

use the standards info about the ostypes to map to our own
(see comment for link to the relevant part of the dmtf schema)

every type that is not listed we map to 'other', so no need to have it
in a list.

changes from v1:
* added comment for test cases why it's 'other'
