vmware虚拟机迁移导致的eth0消失问题

Posted 2020-06-16

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

# #######################################################

# 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 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

gateway 192.168.60.1
netmask 255.255.255.0

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。
