将原来的ubuntu虚拟机文件迁移到还有一台机子之后。
ifconfig显示仅仅有一个lo网卡,网上找了一些文章。大多是改动/etc/network/interfaces
原来内容是
# #######################################################
# This file describes the network interfaces available on your system
# and how to activate them. For more information, see interfaces(5).
# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet dhcp
# #######################################################
将eth0改为静态ip

# The loopback network interface
auto lo
iface lo inet loopback
# The primary network interface
auto eth0
iface eth0 inet static
address 192.168.60.218
gateway 192.168.60.1
netmask 255.255.255.0
# #######################################################
reboot后运行ifconfig,仍然仅仅显示lo,找不到eth0
无意中运行ifconfig -a,显示有eth1,eth2和lo。
于是改动/etc/network/interfaces。将原来的eth0改动为eth1

reboot后,ifconfig最终显示eth1。熟悉的网络又回来了。这里简单记录一下,以免下次再次遇到。
