The hibernated node gets down, started keeps up

A domain status should not be affected by a clone
of itself down in another node.

Also when a domain is up in two nodes it should be
shut down in both nodes immediately

I hope this makes zombie rvd_back disappear

Do this instead shutdown, it is faster to set it up

Thanks to @alexm for this hint. It took a year
but we did it !

So we can find out where it comes from. My guess
the domain was down.

Also many processes can be spawned for start the
domain as it is not costly
