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.
That's a good question.  We know that vdsm captured core files today.  I
don't think there is an API mechanism to retrieve the core files
remotely yet.

If we did propose such a call, what sets of files would we want to
include?  Would this be a query for fetching debug data for a single VM,
for the host (which would/could include all cores and dumps)?

At least, the log files of VDSM(/var/log/vdsm/), the log files of libvirt VMs( /var/log/libvirt/qemu/), VM panic cores and Qemu crash core dumps can be included. Among them, the log files of VDSM are global ones and the others should be queried based on a specific VM.
