^^^^^^^^^^^^^^^^^^^^^^^
An unconnected network interface sounds pretty pointless, but can show up for
example with VMWare when libvirt does not have any more information to provide.
Two such scenarios are currently known:
1) network interface exists, but is not connected to any existing network
2) the interface is connected to something known as VMWare Distributed Switch
The difference between these two is not (yet?) discoverable by libvirt, so at
least the information gathered from the hypervisor is provided in the
element. :since:`Since 8.7.0`
example with VMWare without any specified network to be connected to.

VMWare Distributed Switch
^^^^^^^^^^^^^^^^^^^^^^^^^
Interface can be connected to VMWare Distributed Switch, but since libvirt
cannot provide information about that architecture, the information presented
here is only what can be gathered from the VM configuration. VMs with this
interface type can be created, so that editing of the XML works properly,
however libvirt cannot guarantee that any changes in these parameters will be
valid in the hypervisor. :since:`Since 8.7.0`
