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.
