# HG changeset patch
# User Alastair Tse <atse@xxxxxxxxxxxxx>
# Date 1169486633 0
# Node ID bffe672121336051b58d0fdfbf2f05cb056d524e

[XEND] Fix get_dev_property_by_uuid
This patch replaces calls to get_dev_property() by calls to
get_dev_property_by_uuid() in XenAPI.py and fixes the implementation
of get_dev_property_by_uuid.
I am adding a test case to the xapi grouptests to verify the fixes.
There's a FIXME note in the test case which should be looked at.
