Validating NSD - Getting VIM error

Hi,

I've defined my NSD according to the guide, however, I'm getting the error at the bottom when instantiating the NS, apparently related to the stage where it tries to "open a key file" for the vim.

VNFD files are fine, as VNFs can be instantiated individually without problems. The NSD file refers to the VNFD names specified at the moment of onboarding, not substituting any parameter.

My environment:
- Tacker 0.7.1dev1
- Newton components (python-novaclient 6.0.0 instead of 7.1.0 --> the only requirement not met for current Tacker version)

Thanks,
Gianpietro
