Be more restrictive when matching the port forward used for
SSH. Allow matching simply on the guest port, but also include
extra matching criteria for cases where multiple results may
be returned.
Prior to this commit, the virtualbox synced folder option
`SharedFoldersEnableSymlinksCreate` was always enabled. This commit
introduces a config option and an environment variable which allows
users to configure the option globally or per synced_folder in their
Vagrantfile.
Previously, we required a host-only interface with a static IP for NFS
to work in VirtualBox, because we needed access to the guest's IP in
order to properly configure mount commands.
After boot, VirtualBox exposes the IP addresses of a guest's network
adapters via the "guestproperty" interface.
This adds support for reading VirtualBox guest properties to the
VirtualBox driver and utilizes that support to prepare NFS settings,
which removes the necessity for a static IP for NFS to work.
In this commit we also start building out scaffolding for unit testing
vbox actions and drivers.
Test plan:
- Prepare a Vagrantfile with the following:
* private network with type: :dhcp
* synced folder with nfs: true
- Boot a VM from this Vagrantfile using the virtualbox provider
- Machine should boot successfully with working synced folder
