According to misc/xl-disk-configuration.txt for 4.1.x, doing a grep
string for drdb show nothing... ...

For unstable, see
which I can see drdb there as below:

Description:           Specifies the script (deprecated)
Supported values:      iscsi:  nbd:  enbd:  drbd:

In xend and old versions of libxl it was necessary to specify the
"script" (see above) with a prefix.  For compatibility, these four
prefixes are recognised as specifying the corresponding script.  They
are equivalent to "script=<script>".

According to http://www.drbd.org/users-guide/s-xen-configure-domu.html,
I think can work by using phy instead of drdb but you will need to
manage DRBD state transitions outside of Xen.  The below is what I
read from the drdb site:
Under these circumstances, you must use the traditional phy: device
syntax and the DRBD device name that is associated with your resource,
not the resource name. That, however, requires that you manage DRBD
state transitions outside Xen, which is a less flexible approach than
that provided by the drbd resource type.
