Remove the lines described previously so that your file looks like this: (If you need instructions on using the VI-editor please read this article.) Then the services (vCenter) will load and use the correct IP configuration. One is to modify the MAC Address if you are certain that it is not in use, but the simplest one is to remove all the rules and then restart your system which will detect the current adapter as eth0 and assign the correct IP configuration to your device. There are two approaches to this problem. And since the IP Address configuration was assigned to eth0 your machine no longer has a valid networking configuration. When we look at the second line in this example and compare the MAC Address with the address that the VM has in the vSphere Client or Web Client then you see that it matches the eth1 configuration. In the image below you can see the contents of the udev rules file:

Manual in this case you can define the value of the MAC address manually. Generated MAC Adresses those addresses can be further be separated in two groups, where: Group 1 Assigned by vCenter server. What actually happens is that a new adapter is detected and becomes device eth1. VMware has 3 different ways to allocate MAC addresses, where each one of those is with separate OUI. So when that address changes it breaks this assignment. The problem occurs because SUSE Linux Enterprise Server 11, which is the OS for the appliance, stores the network card configuration for adapter eth0 in the udev-rules based on the MAC Address. In other Linux-servers you could identify this problem when your Linux-OS does not have a valid configuration for the network adatper (eth0). This is what you would see on the console of the virtual appliance: It might happen when you move the virtual machine, clone it, restore it, recover it from replication or perform any other action where the MAC Address of the virtual machine changes. But it could also happen with other Linux-servers. This problem might occur with your vCenter Server Appliance.
