This commit fixes and cleans up instance block_device configuration.
Reverts #5354 in that `volume_size` is only required in certain
block_device configuration combinations. Therefore, the actual
attribute must be set to Optional and later checks done.
Doc upates, too.
This commit adds the ability to create instances with multiple
ephemeral disks. The ephemeral disks will appear as local block
devices to the instance.
This commit adds the ability to associate a Floating IP to a specific
network. Previously, there only existed a top-level floating IP
attribute which was automatically associated with either the first
defined network or the default network (when no network block was
used).
Now floating IPs can be associated with networks beyond the first
defined network as well as each network being able to have their own
floating IP.
Specifying the floating IP by using the top-level floating_ip
attribute and the per-network floating IP attribute is not possible.
Additionally, an `access_network` attribute has been added in order
to easily specify which network should be used for provisioning.
This change better reflects how block devices are passed to the Nova API
and allows for future enablement of block_device features. It also resolves
an interpolation bug.
This commit cleans up the volume and block device handling in the instance
resource. It also adds more acceptance tests to deal with different workflows
of attaching and detaching a volume through the instance's lifecycle.
No new functionality has been added.
This commit fixes the previously broken "boot from volume" feature. It also
adds an acceptance test to ensure the feature continues to work.
The "delete_on_termination" option was also added.
This commit follows suit of #1897 by fixing volume-related
parameters which allow the volume attach acceptance test
to work. It also re-enables the volume attach test.
