虚拟机中的kali linux没有了eth0，只有lo接口了怎么办

问题如下：，没有了eth0

root@kali:~# ifconfig 
lo: flags=73<UP,LOOPBACK,RUNNING>  mtu 65536
        inet 127.0.0.1  netmask 255.0.0.0
        inet6 ::1  prefixlen 128  scopeid 0x10
        loop  txqueuelen 1  (Local Loopback)
        RX packets 70  bytes 3638 (3.5 KiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 70  bytes 3638 (3.5 KiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

首先启动eth0

ifconfig eth0 up

之后在/etc/network/interfaces文件中加入

iface eth0 inet dhcp

最后重启网络

service networking restart 

或者interfaces写成静态ip也行

iface eth0 inet static  
    address 192.168.***.***
    netmask 255.255.255.0

最后perfect

root@kali:~# ifconfig 
eth0: flags=4163  mtu 1500
        inet 192.168.***.***  netmask 255.255.255.0  broadcast 192.168.145.255
