Summary
OpenStack Nova Live migration can leak root disk into ephemeral storage
Details

The icreateimagesandbacking (aka createimagesand_backing) method in libvirt driver in OpenStack Compute (Nova) Grizzly, Havana, and Icehouse, when using KVM live block migration, does not properly create all expected files, which allows attackers to obtain snapshot root disk contents of other users via ephemeral storage.
