Interface names

6.14 KVM guest

The interface names are assigned through udev rules and can vary depending on the distribution.

The network interfaces on Linux® as a KVM guest on IBM® Z are virtual Ethernet interfaces. Often, distributions use interface names of the form eth<n>, where <n> is an index number that identifies an individual interface.

Your distribution might provide interface names that include the MAC address. For example, a udev rule might create interface names like this example: eth-00-00-5E-00-53-00. Because the mapping of virtual network device to MAC address is specified through the virtual server configuration on the KVM hypervisor, it is persistent across reboots.

Tip: Use ip link to display a summary of your interfaces.
