Switch to instance doubles for driver where possible and reduce usage of
allow_any_instance_of.
Additionally replace some incorrect allows with expects to validate
calls are not made.
Ensure the path attribute for disks in the new format is required to
ensure there is always one parameter required for the hash element in
the array of disks. This avoids a certain amount of magical behaviour.
Identify that the name attribute is optional, however add checks for
collisions in volume names generated, as well as ensuring the volumes
are still prefixed in a way to prevent accidental collisions between
boxes utilizing the same names.
Add notes to the README identifying the format as experimental, with
notes on how the format should appear.
When uploading disks to libvirt storage it is unnecessary to require
that the virtual size or the format be provided as these can be
retrieved by calling qemu-img on the box files to retrieve the required
information.
Update the handle box image support to separate the handling of the two
different formats and remove the need to specify the additional settings
in the case of the V2 format for multi disk boxes.
Adds support for a new multi disk box format and handling to upload the
multiple disks to the storage pool.
New format is:
{
'disks': [
{
'name': 'disk1.img',
'virtual_size': 10,
'format': 'qcow2'
},
{
'name': 'disk2.img',
'virtual_size': 15,
'format': 'qcow2'
},
{
'name': 'disk3.img',
}
],
'provider': 'libvirt',
'format': 'qcow2'
}
It is expected to remove format from being set at the top level when
using the new format, with the assuming that qcow2 should be the default
format, and other formats should be permitted to be specified as needed.
Includes tests for handling the box images and creation of domain
volumes. Additionally includes an integration test to ensure a box with
2 disks will work as expected.
