libxl: error: libxl_exec.c:118:libxl_report_child_exitstatus: 
/etc/xen/scripts/block add [14735] exited with error status 1
libxl: error: libxl_device.c:978:device_hotplug_child_death_cb: script: Device 
/dev/dm-3 is mounted in a guest domain,
and so cannot be mounted now.

This is a consequence of 25733:353bc0801b11 "libxl: support custom block
hotplug scripts which had the side effect of re-enabling the hotplug
script's device sharing checks, which in turn has exposed the fact that
during migration xl currently has both devices in existence (but
thankfully not active).

One option might be to nobble those checks again but I'm going to
investigate if I can make xl sequence the device teardowns in the
migration so as to make it work.
