In order to solve task:
http://autotest.kernel.org/ticket/50
Implemented support to providing blkdebug files to arbitrary guest images in
autotest. Also, modified a bit the migrate test and introduced the variant
migrate.with_blkdebug variant, that tries to mimic as much as possible the
testcase described in ticket 50. Kevin, sorry that I took too long to work
on this, let me know if you see any obvious problems on the implementation.
With this we can have people reproducing the test case mentioned with a
stock autotest clone. Indeed we see state migration mismatch problems
running the testcase:
