+# This test initialises a ram disk in dom0 with data from /dev/urandom and
+# then imports the ram disk device as a physical device into a domU. The md5
+# checksum of the data in the ramdisk is calculated in dom0 and also
+# calculated by the domU reading the data through the blk frontend and
+# backend drivers. The test succeeds if the checksums match indicating that
+# the domU successfully read all the correct data from the device.
