Ok, fencing is a requirement for a cluster for hardware failure. I've another question about this arg, but for software failure. Supposing to have a cluster of httpd installation on 6 virtualized hosts, each one on a different server. Suppose also that a guest (named host6) has a problem and can't start apache. With this scenario, the ipmi, ups are unnecessary. How to work fencing in this way? How to make fencing node?
I'm not sure I understand properly... You mean that you have 6 VMs which are nodes in a cluster, or 6 nodes, each hosting a VM you want to make HA?
<snip> I'm not clear on what you mean, either. Is this supposed to be a load-balancing cluster? If so, and you expect that kind of load, I, personally, would *never* put a VM on them - I'd want the full resources of the o/s brought to bear on that load, and use multiple real hardware for the other members. Doing this with VMs is only multi-threading the load, and adding more, with all the context switches.
