About Virtual Network Interfaces

Each virtual machine (VM) may have one or more virtual network interfaces that act as virtual NICs.

A virtual network interface has the following properties:

Network The (physical) network location of the virtual network interface.
MAC address The MAC address of the virtual network interface.
QoS limit An optional I/O priority Quality of Service (QoS) setting for maximum network transfer rate. When memory resources are low, using I/O throttling in this way will slow the memory processing and help make the system more stable by preventing crashes.

You can see all the virtual network interfaces for a VM on the VM’s Networking tab. Here, you can add new virtual network interfaces, as well as edit, activate, deactivate and remove existing ones.
