Virtual network devices

Red Hat Enterprise Linux 9.2 KVM guest

On Linux® as a KVM guest on IBM® Z, you use generic network devices and predictable interface names for Ethernet interfaces.

Read /sys/class/net to obtain a list of interfaces. Each list item corresponds to an online CCW network device.

Example:

# ls /sys/class/net
encf500     enced0

According to convention, the device bus IDs of the associated CCW devices are 0.0.f500 and 0.0.0ed0.

Use ip or an equivalent command to activate an interface.

Example:

# ip addr 192.0.2.5 dev encf500 peer 192.0.2.6
