Access: read-only
Description: The name of the Virtual Machine that owns this virtual ethernet interface. When a Virtual Machine attaches to one of the port in physical server via this virtual ethernet interface, this VM will be considered as the owner of this virtual ethernet interface.
When Virtual Machine moves from one host to another, its virtual ethernet interface remains unchanged.
What is cvnVethOwner?
This identifies the name of the virtual machine currently considered the owner of a virtual ethernet interface. An admin cares because this lets you trace which specific VM is using a given switch port, even as that VM migrates between physical hosts, since the interface identity persists. For example, after a VM is live-migrated to a different physical server, this field for its virtual ethernet interface still shows the same VM name, letting the admin track it across the move.
