Subject: [PATCH] v2v: OVF: Better mapping for inspection data to vmtype.
e76f14
e76f14
The old mapping code was directly copied from old virt-v2v, translated
e76f14
from Perl to OCaml.
e76f14
e76f14
The new mapping code does a few things more accurately:
e76f14
e76f14
 - Use the i_product_variant field (Windows InstallationType) if available.
e76f14
e76f14
 - Simplify rules, so there is only one special case needed for RHEL 3/4.
e76f14
e76f14
 - Don't assume Fedora == Desktop.
e76f14
e76f14
 - Don't assume all later Windows variants are server.
e76f14
e76f14
 - Works for Windows > 7.
e76f14
e76f14
(cherry picked from commit 5ec42a62384f87a4de841d202e31d0337c64f5af)
