Description

It seems the python bindings to Whirr have EBS support:
https://issues.apache.org/jira/browse/WHIRR-3

Let's implement this in the Java implementation. While portable volume support isn't complete in jclouds, EC2 variants (aws-ec2, eucalyptus) do support EBS mappings via the Template:

ex. from org.jclouds.ec2.compute.EC2ComputeServiceLiveTest.testMapEBS()

template.getOptions().as(EC2TemplateOptions.class)//
.mapEphemeralDeviceToDeviceName("/dev/sdm", "ephemeral0")//
.mapNewVolumeToDeviceName("/dev/sdn", volumeSize, true)//
.mapEBSSnapshotToDeviceName("/dev/sdo", snapshot.getId(), volumeSize, true);
