[vdsm] how engine get files from node？

Hi all,
   I have submitted a patch about watchdog device 
http://gerrit.ovirt.org/#/c/7535/
   If we set 'dump' action for watchdog, qemu will generate a dump file.
   And I have get some feedback, how engine get these files?

   scp? or Will vdsm support new API to list and get these files?
   IMO, The new API should  list and get not only dump files,  but also 
other kinds of files.
