最新已经到0.4了，安装也比较简单，可惜家里就一台，那位兄弟给测试一下，给大家说一下效果。

LVS on FreeBSD Version 0.4.0

Install:
1. Patch the FreeBSD kernel:
cp patch/OS-RELEASE/* /usr/src;
cd /usr/src;
patch -p0 < uipc_socket.c.patch
patch -p0 < ip_input.c.patch
patch -p0 < socketvar.h.patch
patch -p0 < sys_conf_options.patch
patch -p0 < sys_i386_conf_GENERIC.patch
2. Rebuilding FreeBSD kernel:
cd /usr/src/sys/arch/i386/conf;
config GENERIC;
cd ../compile/GENERIC;
make depend;
make;
make install;
3. Compile ipvs module:
cd ipvs/
make;
cd ipvsadm/
make install;
4. Compile ipvs scheduler module:
cd ipvs/
cd schedulers/
cd SCHEDULER-NAME/
make
5. Reboot with new kernel:
reboot;

Let''s assume your cluster has the following configuration:
Workstation with address:192.168.1.23 runs as dispatcher(FE:front end),
Workstations with address:192.168.1.33 and 192.168.1.38 run as real server(BE:back end).
Thay all share address:192.168.1.36,which is saw by client.

Start:

Assume using ''rr'' schedule algorithm(optional: dh, lblc, lblcr, lc, nq, rr,
sed, sh, wlc, wrr).

LVS/DR:
1. kldload ./ipvs.ko
2. kldload schedulers/rr/ip_vs_rr.ko
3. ./ipvsadm -A -t 192.168.1.36:80 -s rr
4. ./ipvsadm -a -t 192.168.1.36:80 -r 192.168.1.33:80 -g
5. ./ipvsadm -a -t 192.168.1.36:80 -r 192.168.1.38:80 -g

LVS/TUN:
1. kldload ./ipvs.ko
2. kldload schedulers/rr/ip_vs_rr.ko
3. ./ipvsadm -A -t 192.168.1.36:80 -s rr
4. ./ipvsadm -a -t 192.168.1.36:80 -r 192.168.1.33:80 -i
5. ./ipvsadm -a -t 192.168.1.36:80 -r 192.168.1.38:80 -i

Stop:
1. ./ipvsadm -C
2. kldunload ip_vs_rr
3. kldunload ipvs

Note:Do not use other commands of ipvsadm,for maybe it is not implemented.
