[Bug] Missing virtualbox provider for version 2020.05.04

Created by: Jiehong

All boxes in https://app.vagrantup.com/archlinux/boxes/archlinux are usually provided for 2 providers: libvirt and virtualbox.

However, the latest (2020.05.04), is only published for the libvirt provider.

Would it be possible to also publish it for the virtualbox provider?

To upload designs, you'll need to enable LFS and have an admin enable hashed storage. More information
