Hello,
I've tried to test it. I got "'openstack_compute_instance_v2.test' error: : invalid or unknown key: user_data"
I might have done something bad, but it seems that there is a problem somewhere. It would be great if you could have a look, this would be a killer feature for me.
Have a great day ;-)

@Bersekyr Both the acceptance test and a demo tf file worked for me. If you're getting "unknown key", it sounds like the provider wasn't compiled or moved into place?

@cbuben Do you think you could rebase this against the lastest cleanup patch?

@jtopjian rebased on top of e2e7abf

Is this ready to merge?

[jtopjian]

@cbuben Thanks!

@jrperritt I've done some basic tests and it works. Other than a doc update (which could be a separate patch), I think this is good to go.
