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
