Fixed In Version: openstack-nova-2014.1-3.el7ost
Doc Type: Enhancement
Doc Text:
With this update, the API call for attaching volumes to instances in Compute (servers/[INSTANCE_UUID]/os-volume_attachments) now accepts two additional parameters in the body: disk_bus and device_type. If these parameters are specified, the libvirt driver attempts to honor them when attaching the volume. The following values are accepted: * disk_bus: 'scsi' and 'virtio' * device_type: 'disk', 'cdrom', 'floppy', and 'lun'

Description RHOS Integration 2013-12-12 13:30:54 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/nova/+spec/use-new-bdm-format-in-attach.

Description:

As part of the havana blueprint improve-block-device-handling we added some data that can be associated with the volume. We can now use this data when attaching volumes (not only when booting). Several things will need to be done.

* Add the needed options to the volume-attach API calls in the v3 API
* Make all the attach code paths use the new-format of block devices and not rely on the legacy data format
* Implement the new use of the new format in the libvirt driver.

Assigning to Nikola as he is the current assignee upstream.
Comment 4 Summer Long 2014-03-28 09:56:02 UTC 
Looks like changes are only in the API; no doc impact.
