    The ``XenAPI`` compute driver now supports creating servers with virtual
    interface and block device tags which was introduced in the ``2.32``
    microversion.

    Note that multiple paths will exist for a tagged disk for the following
    reasons:

    1. HVM guests may not have the paravirtualization (PV) drivers installed,
       in which case the disk will be accessible on the ``ide`` bus. When the
       PV drivers are installed the disk will be accessible on the ``xen`` bus.
    2. Windows guests with PV drivers installed expose devices in a different
       way to Linux guests with PV drivers. Linux systems will see disk paths
       under ``/sys/devices/``, but Windows guests will see them in the
       registry, for example ``HKLM\System\ControlSet001\Enum\SCSIDisk``. These
       two disks are both on the ``xen`` bus.

    See the following XenAPI documentation for details: http://xenbits.xen.org/docs/4.2-testing/misc/vbd-interface.txt

Add release note for xenapi virt device tagging support
Add release note for xenapi virt device tagging support

Nova change I565617e05acf33e6254ea091b88d975270ffde05 added
the support for creating a server with tagged VIFs and BDMs
with the xenapi driver, but did not contain a release note.

This adds the release note, and much of the text is copied
from Tempest change I9fe520bc9b68d0bc7f879617f2cd27dd1029e4de.
