you have to turn on one of the options in Networking before you see the
ipvs stuff (I forget which it is)
here's the kernel Network config for an earlier 2.2 kernel. It will
be similar to 2.2.17. The * down the
left side are recommended for a first install of ipvs
[*] Kernel/User netlink socket
[*] Routing messages
< > Netlink device emulation
* [*] Network firewalls
[*] Socket Filtering
<*> Unix domain sockets
* [*] TCP/IP networking
[*] IP: multicasting
[*] IP: advanced router
[ ] IP: policy routing
[ ] IP: equal cost multipath
[ ] IP: use TOS value as routing key
[ ] IP: verbose route monitoring
[ ] IP: large routing tables
[ ] IP: kernel level autoconfiguration
* [*] IP: firewalling
[ ] IP: firewall packet netlink device
* [*] IP: transparent proxy support
* [*] IP: masquerading
--- Protocol-specific masquerading support will be built as modules.
* [*] IP: ICMP masquerading
--- Protocol-specific masquerading support will be built as modules.
* [*] IP: masquerading special modules support
* <M> IP: ipautofw masq support (EXPERIMENTAL)
* <M> IP: ipportfw masq support (EXPERIMENTAL)
* <M> IP: ip fwmark masq-forwarding support (EXPERIMENTAL)
* [*] IP: masquerading virtual server support (EXPERIMENTAL)
* (12) IP masquerading VS table size (the Nth power of 2)
* <M> IPVS: round-robin scheduling
* <M> IPVS: weighted round-robin scheduling
* <M> IPVS: least-connection scheduling
* <M> IPVS: weighted least-connection scheduling
* [*] IP: optimize as router not host
* <M> IP: tunneling
<M> IP: GRE tunnels over IP
[*] IP: broadcast GRE over IP
[*] IP: multicast routing
[*] IP: PIM-SM version 1 support
[*] IP: PIM-SM version 2 support
* [*] IP: aliasing support
[ ] IP: ARP daemon support (EXPERIMENTAL)
* [*] IP: TCP syncookie support (not enabled per default)

It's probably happened to most of us. It
happens everytime you run on a kernel without the lvs patch configured :-)
