  The Large Volume Detector (LVD) at INFN Laboratori Nazionali del Gran Sasso,
Italy is a 1 kt liquid scintillator neutrino observatory mainly designed to
study low energy neutrinos from Gravi- tational Stellar Collapses (GSC) with
100% efficiency over the entire Galaxy. Here we summarize the results of the
search for supernova neutrino bursts over the full data set lasting from June
1992 to May 2016 for a total live time of 8211 days. In the lack of a positive
observation, either in standalone mode or in coincidence with other
experiments, we establish the upper limit to the rate of GSC event in the Milky
Way: 0.1/year at 90% c.l.
