[Xen-devel] [PATCH][XM-TEST] Some adjustments to the restore tests

[Dan Smith <danms@xxxxxxxxxx>]

After inspecting the restore and migrate failures on x86_64, I
realized that the DomUs are oops-ing.  This patch turns on console
debug dumping for the restored-domain consoles so that we can see the
oops messages, as shown here:

Some tweaks to the restore and migrate tests to expose the consoles of the
restored DomUs, since they currently Oops on x86_64.
