Public bug reported:
When cloud-init is used to partition a disk provided by AWS on Ubuntu
v14.04, this fails.
Cloud-init is configured like this:
disk_setup:
/dev/xvdh:
layout: true
overwrite: false
table_type: 'mbr'
This causes cloud-init to fail as follows:

With partitioning having failed, the disk formatting that follows fails
due to the partition not existing.
