Compressing an OVF Package

For maximum compression of an OVF package with multiple virtual machines, set both the
--compress=9
and
--makeDeltaDisks
options. The following are examples of using maximum compression:
> ovftool --compress=9 --makeDeltaDisks package.ovf output-dir > ovftool --compress=9 --makeDeltaDisks vi://localhost/dc/vm/VirtualAppDemo output-dir/
If the source contains only a single virtual machine, the
--makeDeltaDisks
option does not yield any compression boost. In this case, the
--compress=9
option gives maximum compression.
