I've seen the same thing, It looks like ipvsadm is not displaying the
details from lvs correctly.
However looking at a packet capture you can see it is sending traffic to
all servers.
[root@ip-10-0-1-72]# ipvsadm -A -t 10.0.1.72:808 -s rr
[root@ip-10-0-1-72]# ipvsadm -a -t 10.0.1.72:808 -r 10.0.1.73:808 -m
[root@ip-10-0-1-72]# ipvsadm -Ln
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 10.0.1.72:808 rr
-> 10.0.1.73:808 Masq 1 0 0
[root@ip-10-0-1-72]# ipvsadm -a -t 10.0.1.72:808 -r 10.0.1.74:808 -m
[root@ip-10-0-1-72]# ipvsadm -Ln
IP Virtual Server version 1.2.1 (size=4096)
Prot LocalAddress:Port Scheduler Flags
-> RemoteAddress:Port Forward Weight ActiveConn InActConn
TCP 10.0.1.72:808 rr
-> 10.0.1.73:808 Masq 1 0 0
[root@ip-10-0-1-72]# ipvsadm -v
ipvsadm v1.26 2008/5/15 (compiled with popt and IPVS v1.2.1)
This was using ec2 with amazons kernel 3.10.40-50.136.amzn1.i686.
