Yes, it plugged successfully (at least no error messages).

I saw that code in  device.ml (where exception was raised), it seems be 
checking that path in xenstore:

                 (* Sanity check: ensure the backend domain exists *)
                 let _ =
                         try
                                 let (_: string) = t.Xst.read (sprintf 
"/local/domain/%d/vm" device.backend.domid) in
                                 ()
                         with Xenbus.Xb.Noent ->
                                 raise (Device_backend_vanished device) in


But even I was successfull, I unable to perform any IO in guest domain 
(I've get into initrd but I see no /dev/xvd* devices and no messages in 
dmesg related to new device).
