Hello,

I am trying to use this vagrant box but when I run "sudo vagrant up --provider xhyve", I get following error:
The provider 'xhyve' could not be found, but was requested to back the machine 'default'. Please use a provider that exists.

I have xhyve installed on my mac and also vagrant-xhyve plugin

Thanks for the help in advance.

Thanks,
Nupur
