[lvs-users] Install script does not work on 2.6 kernel

["David Dyer-Bennet" <dd-b@xxxxxxxx>]

configure-0.9.4-lvs.pl fails to find the DIP when it's assigned as a
secondary on one of the ethernet ports:

[root@prcapp02 ~]# rc.lvs_nat
[many success reports snipped]
error: not a server, not a director
I'm not a server machine -
this machine doesn't have any of the IPs listed in the SERVICE lines.
I'm not a director - I don't have the DIP 172.17.0.100
bummer - exiting.

It's weird that the configure script expects the DIP to be already
assigned, anyway; that wouldn't normally be assigned when no LVS was
running.  I had to manually assign it just to please configure -- and then
that didn't work either.

The claims about what kernel version are supported are confusing:

[root@prcapp02 ~]# ./configure conf-test-cluster
kernel 2.6.18-92.el5 is being treated as 2.6.17
warning: ./configure has not been tested with kernel version 2.6.17

This seems to me to say that it *does* support 2.6.17 (else why would it
have a concept of treating my kernel as 2.6.17?), but the next line says
it *hasn't* been tested with 2.6.17.

I must say, everything I do to try to set up a simple, understandable
configuration so I can learn enough to go on to do something useful is
rather blowing up in my face.  Bummer.
