[Bug 927808] [NEW] nova-compute fails to attach volumes: FileNotFound: File /etc/iscsi/initiatorname.iscsi could not be found.

[Adam Gandelman]

Public bug reported:

CI is picking up a failure of the volumes exercise.   I believe this is
a result of: https://review.openstack.org/#change,3586

May just be a packaging bug, but volume attach fails on the compute
node:
