** Description changed:
+ SRU Justification
+
+ Impact: Vagrant environments are no longer able to use virtualbox
+ feartures like shared folders. This is due to Ubuntu Cosmic kernels
+ currently shipping the upstream vboxguest module and not importing
+ modules from the virtualbox-guest-dkms package.
+
+ Fix: One solution would be to use the dkms modules for Vagrant, but this
+ is not ideal. At this late stage the simplest solution is to go back to
+ importing the out-of-tree modules.
+
+ Regression Potential: Minimal. Will have no impact outside of virtualbox
+ environments, and the drivers being imported come from the virtualbox-
+ guest-dkms package in cosmic and are thus expected to work well.

In bionic, the vboxsf module was included in linux-modules-...-generic:
$ dpkg -c linux-modules-4.15.0-36-generic_4.15.0-36.39_amd64.deb | grep
vboxsf.ko
-rw-r--r-- root/root 63238 2018-09-24 10:08
./lib/modules/4.15.0-36-generic/kernel/ubuntu/vbox/vboxsf/vboxsf.ko
In cosmic, it isn't:
$ dpkg -c ~/Downloads/linux-
modules-4.18.0-9-generic_4.18.0-9.10_amd64.deb | grep vboxsf.ko
This results in shared folders no longer being mountable in Ubuntu
Vagrant boxes (and, as the other vbox modules are also missing, probably
has other effects that haven't yet been reported).

[Original Report]
Just tried to test out the new cosmic64 vagrant box and get the
following error;
```
Vagrant was unable to mount VirtualBox shared folders. This is usually
because the filesystem "vboxsf" is not available. This filesystem is
made available via the VirtualBox Guest Additions and kernel module.
Please verify that these guest additions are properly installed in the
guest. This is not a bug in Vagrant and is usually caused by a faulty
Vagrant box. For context, the command attempted was:
mount -t vboxsf -o uid=1000,gid=1000 vagrant /vagrant
The error output from the command was:
/sbin/mount.vboxsf: mounting failed with the error: No such device
```
I tried with ubuntu/bionic64 and it worked fine.
I've got;
$ vagrant version
Installed Version: 2.1.5
Latest Version: 2.1.5
You're running an up-to-date version of Vagrant!
$ VBoxManage --version
5.2.18r124319
