Hi,

I've got an issue related to configuration of attached volume device name
in Horizon. That option is not supported by all hypervisors (see
https://bugs.launchpad.net/nova/+bug/1075971,
https://bugs.launchpad.net/nova/+bug/1217874 ) and in Icehouse it is hidden
by default. The visibility of that option is configured by section in
local_settings.py (
https://github.com/openstack/horizon/blob/stable/havana/openstack_dashboard/local/local_settings.py.example
):

OPENSTACK_HYPERVISOR_FEATURES = {
    'can_set_mount_point': True,
}

However In Icehouse the same option is:

# The Xen Hypervisor has the ability to set the mount point for volumes
# attached to instances (other Hypervisors currently do not). Setting
# can_set_mount_point to True will add the option to set the mount point
# from the UI.
OPENSTACK_HYPERVISOR_FEATURES = {
    'can_set_mount_point': False,
    'can_set_password': True,
}

What will be the default value of that option in upcoming Fuel 4.0?

Thanks,
Ilya

PS. Two more patches related to the same issue with device attachment:

   - https://review.openstack.org/#/c/60261/ - merged into Horizon on Dec
   12th, it adds a notice "Actual device name may differ due hypervisor
   settings."
   - https://review.openstack.org/#/c/60257/4 - on review, the patch
   introduces warning when hypervisor is not able to attach volume with
   specified name
