Well there's the confusing part. You had said:
I even use it on Netfilter firewalls without any trouble (without
the LVS support).
It's the 'without the LVS support' that caught my eye.
The docs didn't make it clear that I could do any of this without
LVS-related kernel patches. Further backing that, you now say:
All you have to do is patch your kernel with LVS or use the
appropriate netfilter-ipvs-modules, compile and install keepalived
and configure it according to the documentation and/or your special
So I guess I've either misunderstood or asked the wrong question(s).
Because the documentation all seems to revolve around LVS
implementations. It's not clear which pieces are optional--unless I'm
interpreting it incorrectly.
