Code review comment for lp://qastaging/~springfield-team/charms/trusty/vem/next

Shiv,

Thanks for your contribution to the Juju Charm community, specifically to the VEM charm.

Per Jorge's comment and recent charm testing the charm is still failing make test:
http://reports.vapour.ws/charm-tests/charm-bundle-test-10821-results/charm/charm-testing-aws/2
ERROR: Failure: Exception (Please define the N1KV_SOURCE environment variable)

If you could help fix the N1KV_SOURCE error this will help validate your proposed changes.

-thanks,
Antonio
