[pve-devel] [PATCH storage v7 05/11] ovf: implement parsing out firmware type

[Dominik Csapak]

it seems there is no part of the ovf standard that handles which type of
bios there is (at least i could not find it). Every ovf/ova i tested
either has no info about it, or has it in a vmware specific property
which we parse here.
