I am not sure this question is a great fit for SF, in part because I am not sure the situation you describe fits within the topics you can ask about here.

It isn't clear from your question if you have the required rights to do what you are trying to do - are you the VM administrator, and are you able to configure/modify any parts of the setup?

You may find some use in looking into virsh, notably its iface-* operations. Alternatively, if you are comfortable with vi and XML, you can virsh edit your guest to add a NIC.

The fact you have no options to edit your guest via virt-manager would however suggest you may not have enough access/rights to do what you are trying to do.

  • I have root access and i want to add additional NIC to configure teaming, but i am unable to find any option on virt-manager, even when the guest is power-off there is no option to edit the config – Vijay Muddu Mar 24 '17 at 4:44

If you use Cloudstack, you can do this easily. Cloudstack has option to choose particular bridge for guest traffic.

If you are not using Cloudstack, create another bridge with new nic and edit the xml file directly and replace the existing bridge in configuration file with new bridge.
