**请先关闭 firewalld和selinux**

#systemctl stop firewalld
     #vi /etc/selinux/config

**将selinux=enforcing 改为 disabled**

1、安装KVM

\#yum -y install qemu-kvm libvirt virt-install virt-manager virt-top libguestfs-tools

2、启动并设置开机启动libvirt

4、修改网卡配置文件(以自己实际联网网卡为准)

## 请注意，下一步中的br0的网桥的配置文件中的ip等相关操作要与之对应的网卡相匹配，否则会导致后续的网络连接错误 ##

5、新增网桥br0配置文件  
\[root@fl-client ~\]\# vi /etc/sysconfig/network-scripts/ifcfg-br0

TYPE=bridge
    BOOTPROTO=static
    NAME=eth1
    DEVICE=br0
    ONBOOT=yes
    NM_CONTROLLED=no
    IPADDR=192.168.200.10
    NETMASK=255.255.255.0
    GATEWAY=192.168.200.2

6、禁用网络过滤器并重新加载kernel参数  
\[root@fl-client ~\]\# vi /etc/sysctl.conf

net.ipv4.ip_forward=0
    net.bridge.bridge-nf-call-ip6tables=0
    net.bridge.bridge-nf-call-iptables=0
    net.bridge.bridge-nf-call-arptables=0

使其生效

sysctl -p

7、重启网络服务

[root@fl-client ~]# systemctl restart network
    [root@fl-client ~]# systemctl restart NetworkManager

8、验证内核模块

10、创建虚拟机通过命令virt-manager启动图形界面
