Jim, Thanks a lot for your confirmation. Could you also please explain if the issue can be ever fixed, if it's possible to make some patch to fix it? Is it libvirt-specific bug or Libvirt development team rely on some other developers of libxl code...etc? I'm asking because XL tools works fine and I wonder if XL uses the same libxl libraries , doesn't it? Lastly is the issue is going be fixed in near time? Can you answer my questions and ask for some patch for enhancement request or I should better send a separate email to development team ("libvir-l...@redhat.com <https://www.redhat.com/mailman/listinfo/libvir-list>") ? Thanks a lot in advance for your answers...
