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.
