That kind of worked. I disabled KeepAlives in apache2 and now the boxes
don't get overloaded with 100 users, but it still does not load balance
watch -n1 "netstat -an | grep \":80 \" | wc -l"
yeilds ~20-30 on realserver 1 and ~1 on realserver2

the search engine on the LVS documentation would be a better place to
look.

If the client is making the connections from the same IP _and_ the httpd
has persistence on (this is a different persistence to the ip_vs
persistenc), then none of your connections will close (look on the
realserver with `netstat` you'll only have one connection to the
client) and you'll always go to the same realserver.
Otherwise the connections should terminate (you'll have 100's of
FIN_WAIT on the realserver with netstat) and you should get
loadbalancing.
(Someone else was having trouble getting load balancing with http
requests
recently - but I never found out what the problem was)
