A couple of examples might be:

* load-balancing applications

IP management (depending on the underlying management)

I'm looking into ways of automating these steps, hence the question
on SNMP or alternate ways to do remote management. I prefer a
trigger->reply mechanism to accomplish these tasks.
However, there is an easier way to better the uptime, using the lvs
way. The only issue here is keeping 2 vservers online and in-sync
the latter is probably the hardest part ;)
