[lvs-users] Keepalived and LVS : invalid protocol and bad address

[Henri Storn <henri.storn@xxxxxxxxx>]

Hello,

I want to create a Web cluster with Keepalived using LVS-DR.Keepalived 
launching, I get the following errors :

"Dec 22 09:58:16 cesar kernel: IPVS: set_ctl: invalid protocol: 0 
192.168.0.10:80 rr
Dec 22 09:58:16 cesar Keepalived_healthcheckers: IPVS: Bad address"

Manually, I'm able to add the virtual IP address and the real servers 
but with Keepalived,I still have that same error.

Can you help me ?

Thanks,

Regards.
