Public bug reported:

The compute API 2.60 microversion allows attaching multiattach-capable
volumes to server instances.

However, when attempting to do so in Horizon it fails because Horizon
doesn't specify microversion 2.60 during the attach call to nova (see
screenshot).

And you can see the error in the nova-api logs:

[None req-9e43e495-a9ee-4460-85bb-1545ce1efbeb demo demo] Returning 400
to user: Multiattach volumes are only supported starting with compute
API version 2.60.

Note that if Horizon is using python-novaclient for the attach volume
call, it must have novaclient >= 10.1.0:
