Build Instability with Virtualbox 6.0

[JGillam]

The build seems to have some issues under VirtualBox 6.0. Specifically the common error seems to be problems resulting in an inability to mount the /vagrant share folder after the reboot in the bootstrapping process. This has taken a couple of forms. One is the following error:

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

And the other is:

[samuraiwtf] GuestAdditions seems to be installed (6.0.6) correctly, but not running. Followed by other related errors as a result of Guest Additions not running.

This issue can be resolved manually by:

• making sure the kernel headers are installed
• reinstalling Guest Additions
• vagrant reload
• vagrant provision

This seems to have resolved itself with the base box build in Samurai 5.0. Fixed in PR #141
