net.bridge.bridge-nf-call-ip6tables = 0

安装kvm时我们需要设置bridge。当我们安装bridge-util后，会发现/etc/sysctl.conf中添加了与防火墙相关的参数。但是当我们执行sysctl -p时，报错说key未知。这是因为我们没有加载bridge模块，需要手工加载。解决过程如下：

[root@vm6 ~]# sysctl -p
net.ipv4.ip_forward = 1
net.ipv4.conf.default.rp_filter = 1
net.ipv4.conf.default.accept_source_route = 0
kernel.sysrq = 0
kernel.core_uses_pid = 1
net.ipv4.tcp_syncookies = 1
error: "net.bridge.bridge-nf-call-ip6tables" is an unknown key
error: "net.bridge.bridge-nf-call-iptables" is an unknown key
error: "net.bridge.bridge-nf-call-arptables" is an unknown key
kernel.msgmnb = 65536
kernel.msgmax = 65536
kernel.shmmax = 68719476736
kernel.shmall = 4294967296

[root@vm6 ~]# lsmod|grep bridge
[root@vm6 ~]# modprobe bridge
[root@vm6 ~]# lsmod|grep bridge
