OVFTool - Error: SHA digest of file ExortedVM.ovf does not match manifest

Was able to go around this problem in ovftool by adding the flag '--skipManifestCheck'

which does create a manifest file, but does not check its validity, for example:

ovftool --machineOutput --overwrite --compress=9 --noImageFiles --skipManifestCheck --targetType=OVA ...

It looks like a bug: The manifest-checking part of the tool is not aware of the fact that the ISO was left out,

tries to validate its key, and fails because the ISO is not there at all...

Cheers
