> Project: Libcloud
> Issue Type: Improvement
> Components: Compute
> Affects Versions: 0.11.2

>
> When creating an EC2 node that utilizes EBS-backed root storage the ephemeral instance storage disks are not available unless explicitly requested by including BlockDeviceMappings in the call to RunInstances.
> This patch adds support for passing an array of BlockDeviceMappings to the EC2NodeDriver's create_node() function using the ex_blockdevicemappings kwarg.
> Example:
> ```
> ec2_ephemeral_mappings = [{'DeviceName': '/dev/sdb', 'VirtualName': 'ephemeral0'},
> {'DeviceName': '/dev/sdc', 'VirtualName': 'ephemeral1'},
> {'DeviceName': '/dev/sdd', 'VirtualName': 'ephemeral2'}]
> ec2.create_node(name=name, image=image, size=size, ex_blockdevicemappings=ec2_ephemeral_mappings)
> [{'DeviceName': '/dev/sdb', 'VirtualName': 'ephemeral0'}]
> ```
> also on github, branch: https://github.com/pantheon-systems/libcloud/tree/ec2_block_dev_mappings
