Successfully imported the appliance.

Then list your VMs to find the VM ID:

$ VBoxManage list vms 
"UCS 4.1" {acef4c0a-35be-4640-a214-be135417f04d}

You can now package that VM as a Vagrant box:

$ vagrant package --base acef4c0a-35be-4640-a214-be135417f04d --output UCS.box 
==> acef4c0a-35be-4640-a214-be135417f04d: Exporting VM... 
==> acef4c0a-35be-4640-a214-be135417f04d: Compressing package to: /home/crohr/dev/ucs/UCS.box

And add it to the list of your local Vagrant boxes:

$ vagrant box add UCS.box --name UCS

Finally, you can create a Vagrantfile to use this box:

Vagrant.configure("2") do |config| 
   config.vm.box = "UCS" 
   # ... 
end

And vagrant up.
