Change Virtual Network Interface Properties

Oct 09, 2015

To change properties of a virtual network interface, open the Virtual Interface Properties dialog box by doing one of the following:

  • Click on the VM's Networking tab, then select the virtual network interface and click Properties.
  • On the Network page of the New VM wizard, click Properties.

You can change the network location and MAC address of a virtual network interface, and you may also be able to set its I/O priority.

Network The network location of the virtual network interface.
MAC address The MAC address of the virtual network interface can be autogenerated or you can enter it manually in the form XY:XX:XX:XX:XX:XX where X is any hexadecimal digit, and Y is one of 2, 6, A or E.
Enable QoS limit Select this option and enter a value in kilobytes per second (kB/s) to set 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.

If the pool is configured to use a vSwitch Controller, the QoS option here will be unavailable; in this case, you should configure QoS settings using the vSwitch Controller, if required.
