[Nix-dev] Nixops fails to log into virtualbox machines on osx.

[Maarten Hoogendoorn]

Hi there,

As mentioned in the previous email I sent to the list, I'm trying to work
with nixops on osx.

The next error I encountered is that nixops is unable to log in to the VM's
due to unknown host keys, see the (partial) output of nixops deploy below:
