BZ #9 854 57

With this release, Red Hat Enterprise Linux OpenStack Platform

supports resizing a volume, using the extend_volume parameter.

This would add an API call to specifically extend the size of an

existing volume that is currently in an available state.

BZ #9 854 58

Red Hat OpenStack now allows the transfer of ownership of Block

Storage Volumes, by providing a mechanism to let another tenant

take ownership of a volume.

This can be used, for instance, when bespoke bootable volumes or

volumes with large data sets are produced by a supplier, and then

transferred to a customer.

The process requires that both parties agree to the operation and

can securely exchange an authorization key. Once the volume is

created, it can be transferred to the end-user using this process.

Feature: Scheduler hints which allow users to pass in extra

information that a Cinder scheduler can use to make decisions

about volume placement.

Reason: New feature in OpenStack Havana

BZ #9 859 53

A feature has been added to OpenStack Block Storage which allows

migrating a block storage volume from one backend to another. This

is an admin-only interface used for manually invoking volume

migration. It is useful for manual tuning and scripting.

BZ #9 86 053

A feature has been added to bind a token to a kerberos token. This

has been added to circumvent the following scenario:

The current security model involves bearer tokens. This means, if

you hold the token, then you are the specified user and have all

the privileges associated with it.

If another user were to acquire that token, they too become that

user with all those privileges.

Binding a token means that a user must have both a token and the

associated cryptographic identity (in this case kerberos ticket)

for the token to be valid.

Tokens can be optionally bound to a Kerberos ticket.
