Libvirt instead of VirtualBox error

Hi, I am using CentOS and during make vagrant up command I got next:
Bringing machine 'default' up with 'libvirt' provider...
==> default: Box 'hashicorp/precise32' could not be found. Attempting to find and install...
default: Box Provider: libvirt
default: Box Version: >= 0
==> default: Adding box 'hashicorp/precise32' (v0) for provider: libvirt
default: Downloading: http://files.vagrantup.com/precise32.box
The box you attempted to add doesn't match the provider you specified.

Provider expected: libvirt
Provider of box: virtualbox

Seems like Vagrantfile support only VirtualBox images? Is it possible to add both configurations?

yes, you're right, right now it is only for VirtualBox images. By "both" what do you mean? Other providers like VMWare?

I mean support libvirt/KVM and of course other providers, if you wish)

I see. It was planned. I'll add it.

That would be great!
