Solve Fatal:error inserting Ip_vs ... Unknown symbol in module, or Unknown parameter

after installing the LVS management tool using the Yum install ipvsadm-y, it is found that the instruction Ipvsadm related instructions have been error:

Fatal:error inserting Ip_vs (/lib/modules/2.6.32-358.18.1.el6.x86_64/kernel/net/netfilter/ipvs/ip_vs.ko): Unknown Symbol in module, or unknown parameter (see DMESG) Can ' t initialize ipvs:protocol don't availableare you sure that IP Virtua L Server is built in the kernel or as module?

Search the Web for related documents, say that there is a template is not loaded, and then execute the loading module

Modprobe Ip_vs

But there is still an error, unable to load the module

At first I thought it was the module loading problem, but later noticed the following prompt see DMESG

Then start viewing the log, or follow the prompts to execute the DMESG

[Email protected] ~]# tail-n100/var/log/messages

Ip_vs:unknown symbol Ip6_local_out
Ip_vs:unknown symbol Ip6_route_me_harder
Ip_vs:unknown symbol IPV6_DEV_GET_SADDR
Ip_vs:unknown symbol Ip6_route_output
Ip_vs:unknown symbol Icmpv6_send

According to the prompt, does not turn on the IPv6 function

Look at the IP information, sure enough not to open IPv6

[[Email protected] ~]# IP A

Modify IPv6 related configuration (I turned off the IPV6 function when I initialized it)

[Email protected] ~]# vim/etc/modprobe.d/modprobe.conf
Options IPv6 disable=1
Alias net-pf-10 off

This may just be one of the causes of this problem, and here is a note, for your reference,
