Stefano Garzarella 5c81161f80 virtio-blk: add "discard" and "write-zeroes" properties ... In order to avoid migration issues, we enable DISCARD and WRITE_ZEROES features only for machine type >= 4.0 As discussed with Michael S. Tsirkin and Stefan Hajnoczi on the list [1], DISCARD operation should not have security implications (eg. page cache attacks), so we can enable it by default.
