Network block device is pretty stable. 1.17 +It was originaly thought that it is impossible to swap over TCP; 1.18 +this turned out not to be true. 1.19 +However, to avoid deadlocks, you will need at least Linux 3.6. 1.20 + 1.21 +It is possible to use NBD as the block device counterpart of FUSE, 1.22 +to implement the block device's reads and writes in user space. 1.23 +To make this easer, recent versions of NBD (3.10 and above) 1.24 +implement NBD over a Unix Domain Socket, too.
