[Xen-devel] [PATCH][XM-TEST] Add test for save/restore with a block device

[Dan Smith <danms@xxxxxxxxxx>]

This patch adds a new test that attempts to save and restore a domain
with a block device attached.  It starts up a domain, mounts a block
device, writes data to it, saves, restores, and then verifies that the
block device can still be read.
