    <div>There's issue with NFS: if you try to
      send over it more than network can deal with (100-120 MBps for
      1-gigabit), it imposes several-second pauses, which are being
      interpreted like hardware errors. These bursts may be just few
      seconds long to trigger issue.<br>
      <br>
      You can try to limit bandwidth in virtual HDD config to something
      like 60-70 MBps. This should be enough for 1-gigabit network.<br>
      <br>
      But my opinion is that it's better to switch to iSCSI.<br>
