Re: [libvirt] [PATCH] docs: Discourage users to set hard_limit

In one of my previous patches I am removing the hard_limit heuristic to guess the correct value if none set. However, it turned out, this limit is hard to guess even for users. We should advise them to not set the limit as their domains may be OOM killed.
