Description of problem:

In RHEV-H TUI there should be an option to set up separate interfaces for management and other purposes, for example self-hosted engine Storage Domain.
Currently  using TUI we can set  set second interface.

The purpose for that is self-hosted engine implementation. It is wise to use different network for self-hosted engine Storage Domain. As well it is highly desirable to set different MTU as well to use jumbo frames. 


How reproducible:

always

Steps to Reproduce:
1. set network interface using RHEV-H TUI
2. try to set up next network interface
3. message appears: 
"Confirm Network Settings
Network Configuration detected an already configured NIC. The configuration for that NIC is going to be removed if changes are made. Proceed?"

Actual results:

can't add an additional network interface

Expected results:

can add an additional network interface and set required MTU
