+# This test imports a ram disk device as a physical device into a domU.
+# The domU initialises the ram disk with data from /dev/urandom and calculates
+# the md5 checksum of the data (using tee as it is written so as to avoid
+# reading it back from the device which might potentially mask problems).
+# The domU is stopped and the md5 checksum of the data on the device is
+# calculated by dom0. The test succeeds if the checksums match, indicating
+# that all the data written by domU was sucessfully committed to the device.
