KVM配置

安装依赖包（因最小化安装）

[root@slave-master ~]# yum install -y vim wget tree  lrzsz gcc gcc-c++ automake pcre pcre-devel zlib zlib-devel openssl openssl-devel iproute net-tools iotop  lsof  ntpdate telnet bridge-utils -y

安装kvm相关的包

[root@slave-master ~]# yum install qemu-kvm qemu-kvm-tools libvirt libvirt-client virt-manager virt-install -y

启动libvirt虚拟网卡

[root@slave-master ~]# systemctl start libvirtd
[root@slave-master ~]# systemctl enable libvirtd  #添加开机自启动

配置网卡绑定
