Eth0 cannot be found after cloning Ubuntu Virtual Machine on Vmware

Ubuntu 8.04.1 server is installed on Vmware, and a virtual machine is cloned. Eth0 disappears and an eth1 error occurs.

The reason is that Ubuntu records the MAC address of the NIC. The MAC address of the original VM is recorded as eth0. After cloning, VMWare assigns a new MAC address to the VM to avoid conflicts. In ubuntu, the newly discovered address is set to eth1.

In ubuntu 7. X, the corresponding file is the/etc/iftab file. In ubuntu 8.04.1, the corresponding file is:

/Etc/udev/rules. d/70-persistent-net.rules

Modify the file directly and delete the row corresponding to eth0. Modify the "eth1" of the corresponding line of eth1 to "eth0.

Another method is to delete all the contents and restart the system. The system also discovers the hardware of the NIC and generates the file again.
