This commit adds a new VirtualBox provider helper method to return a
list of storage controllers so Vagrant can find a storage controller
with the desired characteristics (type IDE or SATA).
This still needs to get wired up to the disk cleanup method.
This builds on the existing disk functionality, and adds some special
IDE controller-related flavor.
Considerations for IDE controllers:
- Primary/secondary attachments, so that each port can have two devices
attached
- Adding the ability to address a specific controller name for disk
attachment
This also prevents a user from attaching multiple instances of the same
ISO file, because VirtualBox will assign each of these the same UUID
which makes disconnection difficult. However, if multiple copies of the
ISO are attached to different devices, removing the DVD config will
cause the duplicate devices to be removed.
We may want to consider additional work to make the storage controllers
truly generic.
Prior to this commit, the default value of disk_ext was set in the
finalize! method, and was really only valid for the virtualbox provider.
This commit updates that by moving the step into the validate function,
which has access to the machines provider.
* hostname is a boolean
* a network that sets hostname should have a static ip address
* only one network may set hostname
can be set at `config.vm.network :public_network, hostname: true, ip: "192.168.0.1"`
Prior to this commit, if a created but exited container bound a port,
and a new container grabed that same port (say for an ssh port forward),
when the initial container came back up it would fail because the port
also got bound to the second container. This commit fixes that behavior
by first looking at what containers are already bound prior to creating
a container.
This commit fixes a test that only fails on certain users machines where
Vagrant ends up trying to run real guest capabilities to test if the
docker provisioner raises an error if the provisioner install failed. It
fixes it by mocking out the expected return values for those
capabilities rather than relying on them actually running for this
specific unit test.
