[CentOS] Keepalived vrrp problem

Hey guys,

 I'm trying to install keepalived 1.2.19 on a centos 6.5 machine. I did an
install from source.

And when I start keepalived this is what I'm seeing in the logs. It's
reporting that the VRRP_Instance(VI_1) Now in FAULT state.

Here's more of that log entry:

And if I do an ifconfig command I see no evidence of an eth1 existing. Also
I can't ping the virtual address that I'm trying to create:

# ping -c 5 10.40.116.34
PING 10.40.116.34 (10.40.116.34) 56(84) bytes of data.>From 10.40.116.30 icmp_seq=2 Destination Host Unreachable

--- 10.40.116.34 ping statistics ---
5 packets transmitted, 0 received, +4 errors, 100% packet loss, time 14001ms

Here are my configs starting with the first machine:

# cat keepalived.conf
vrrp_instance VI_1 {
interface eth1
state MASTER
virtual_router_id 51
priority 101                   # 101 on master, 100 on backup

vrrp_unicast_bind 10.40.116.30   # Internal IP of this machine
vrrp_unicast_peer 10.40.116.31   # Internal IP of peer
virtual_ipaddress {
 10.40.116.34
}

And here's the config on the second machine:

# cat /etc/keepalived/keepalived.conf
vrrp_instance VI_1 {
interface eth1
state MASTER
virtual_router_id 51
priority 100                   # 101 on master, 100 on backup
vrrp_unicast_bind 10.40.116.31   # Internal IP of this machine
vrrp_unicast_peer 10.40.116.30   # Internal IP of peer
virtual_ipaddress {
 10.40.116.34
}


Does anyone have any experience in solving this kind of problem? Any
suggestions on how to resolve this would be great.

Thanks,
Tim

Two stupid questions:
  1. Why are you running 6.5, rather than 6.7?
  2. On the host, does it *have* an eth0, or is it, perhaps, em1?

        mark "it's all emx on Dell R720's"

"ifconfig -a" will show you all of your interfaces.

Maybe there is a confusion here. Sounds like Tim thought keepalived 
would create that eth1, like a tunnel interface, but it won't. You have 
to specify an interface that actually exists so that the VIP address 
will be added as a secondary address to ip to that interface.
