Vmware clone centos modify linux mac address Device eth0 does not seem to be present, delaying initialization fault Background: an existing centos virtual machine is completely cloned in vmware workstation, after startup, the NIC is not started. Restart the network service and find the error message "Device eth0 does not seem to be present, delaying initialization. "www.2cto.com Fault Cause: Due to the clone of the virtual machine, vmware only modified the Virtual Machine name and other information, and did not modify any information in the virtual hard disk, as a result, the MAC address of the cloned Nic does not match the mac address recorded in the operating system, and eth0 cannot be started. The operating system records the addition of a new Nic. The new Nic name is eth1, And the mac address is the new mac address assigned by vmware. Solution: Modify/etc/udev/rules. delete eth0 information from the d/70-persistent-net.rules file. Modify the NIC name of the second eth1 to eth0. modify the mac address in/etc/sysconfig/network-scripts/ifcfg-eth0 to/etc/udev/rules. the mac address of eth0 modified by d/70-persistent-net.rules. Restart the server.
