通过 nmcli connection show 命令可以查看识别的网卡名称。
[root@localhost ~]# nmcli connection show
名称 UUID 类型 设备
ens33 f45a714b-7ccc-4e58-9f52-e8a6c3027a15 802-3-ethernet ens33
virbr0 32b28b6a-4b00-4e7c-9a41-2217b2c25449 bridge virbr0
虚拟机的网卡配置文件在/etc/sysconfig/network-scripts/ 路径下。vincen这里举例配置ens33网卡的ipv4的方法
[root@localhost ~]# cd /etc/sysconfig/network-scripts/ #网卡配置文件的路径
[root@localhost network-scripts]# ls
ifcfg-ens33 ifdown-isdn ifup ifup-plip ifup-tunnel
ifcfg-lo ifdown-post ifup-aliases ifup-plusb ifup-wireless
ifdown ifdown-ppp ifup-bnep ifup-post init.ipv6-global
ifdown-bnep ifdown-routes ifup-eth ifup-ppp network-functions
ifdown-eth ifdown-sit ifup-ib ifup-routes network-functions-ipv6
ifdown-ib ifdown-Team ifup-ippp ifup-sit
ifdown-ippp ifdown-TeamPort ifup-ipv6 ifup-Team
ifdown-ipv6 ifdown-tunnel ifup-isdn ifup-TeamPort
[root@localhost network-scripts]# vim ifcfg-ens33 #修改网卡ens33的配置
TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static #默认是dhcp，这里修改为static 静态分配
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy
NAME=ens33
UUID=f45a714b-7ccc-4e58-9f52-e8a6c3027a15
DEVICE=ens33
ONBOOT=yes #默认是no，这里修改为yes 允许启动此网卡
IPADDR=172.25.0.1 #增加项，增加的ip为172.25.0.5
PREFIX=16 #增加项，增加的子网掩码为16
GETAWAY=172.25.0.3 #增加项，增加的网关为172.25.0.3（此网关是根据Windows上的网络共享中心里的VNnet1的IP地址的）
DNS1=8.8.8.8
配置完成后重启网卡
[root@localhost network-scripts]# service network restart #重启网卡命令重启网卡成功后，通过ifconfig 命令可以查看网卡名称以及具体信息，比如网卡相对应的IP、子网掩码、网关等等。vincen的虚拟机里第一张网卡名（最左边）是ens33，IP（inet）是172.25.0.5，子网掩码（netmask）255.255.0.0
[root@localhost ~]# ifconfig

此时，linux的IP就已经配置成功了
