[Xen-devel] [PATCH] xm-test block device write verify test

[Harry Butterworth <harry@xxxxxxxxxxxxxxxxxxxxxxxxxxxxx>]

>From the patch:

+# 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.
+

This patch also enables tee and fancy head in busybox on the ramdisk.  I
have tested the patch with both `make existing' where the tests run but
the new test fails because the ramdisk is missing tee and fancy head and
`make` where the test passes successfully.

The patch also installs the block-integrity tests in the default test
set so they get executed.
