[DRE-maint] Bug#946837: vagrant: Does not work with virtualbox 6.1 from unstable

[Guillem Jover]

Package: vagrant
Version: 2.2.6+dfsg-1
Severity: serious

Hi!

The package does not work anymore since virtualbox 6.1 got upload to
unstable.

To get this working this just requires a couple of changes, which can
be easily applied as a local patch. Something like what is described
at <https://github.com/oracle/vagrant-boxes/issues/178#issue-536720633>.

Thanks,
Guillem
