The OpenStack drivers supports to boot from volumes. It is possible to specify the volume size of the used volume. It is not possible to specify the volume type that should be used. This is possible in the AWS & GEC driver. We asked upstream, there is no reason that this feature is not possible in the OpenStack driver, it is just not implemented.
Add a volume-type parameter in the OpenStack driver that allows to specify the volume type that should be used when boot-from-volume is enabled. I think it makes sense to have None as default for the new parameter to not change the default behaviour of the OpenStack driver when booting from volumes.
