ZStack identifies NIC names according to your configuration. The NIC No. of all compute nodes in the same cluster must be the same.
- If you already added an eth0 L2 network, but the NIC of the new compute node is em01, not eth0, you will fail to add a host.
- If you chose eth0 when you add an L2 network, you must configure the eth0 network for all compute nodes.
- You can also set em01 as an L2 network. In this case, you must configure the em01 network for all compute nodes.
- You can delete an L2 network and configure it again.
