mac 虚拟机启动网络报错Connection activation failed: No suitable device found for this connection

systemctl network start

找不到命令是因为 centos8没有了network 而是nmcli 代替了

1 排查本机的ip netmask mac地址是否一致

2 mac机

ifconfig

我的虚拟机使用是nat模式如果是桥接模式就看vmnet1

如果子网掩码是乱码就看

上面的 IP 子网掩码路由器要仔细查看且虚拟机的要跟本机同一个网段

登陆虚拟机

vim /etc/sysconfig/network-scripts/ifcfg-ens33

TYPE=Ethernet
PROXY_METHOD=none
BROWSER_ONLY=no
BOOTPROTO=static #如果动态获取设置为dhcp
DEFROUTE=yes
IPV4_FAILURE_FATAL=no
IPV6INIT=yes
IPV6_AUTOCONF=yes
IPV6_DEFROUTE=yes
IPV6_FAILURE_FATAL=no
IPV6_ADDR_GEN_MODE=stable-privacy

#UUID=e270f781-e07d-4cc6-8ca7-9a05eb6ffa61

DEVICE=ens33
ONBOOT=yes #开机启动
#HWADDR=00:50:56:25:DD:1E
HWADDR=00:50:56:29:BB:53 #mac 地址
IPADDR=192.168.85.131  #自定义ip地址  要跟本机同一个网段
#IPADDR=10.10.107.110
NETMASK=255.255.255.0 #子网掩码要跟本机一致
PREFIX=24
IPV6_PRIVACY=no

mac地址

以上都确认无误后就使用nmcli启动网络

>>service NetworkManager start>>nmcli networking on>>nmcli con up ens33  #加载网卡
