There was a module in core that was using vagrant to bring up virtualbox guests (or others).
To me, this feels weird, as you could use the underlying virt technology if you wanted to do that, and if you were using vagrant, most likely you were using the vagrant CLI and ansible provisioner directly.
Since the provisioner is now in Vagrant core, it does not make sense to include the ansible module to /invoke/ vagrant, and as such, I am removing it from 1.2… just because I tend to think it’s a strange inversion, and ansible calling vagrant calling ansible tends to make my brain melt.
I would definitely encourage everyone to check out the Vagrant provisioner in 1.2 if you like Vagrant, and I suspect the vagrant ansible mdoule that was there could be maintained outside of ansible core successfully for those that did want to something like that.
