adding two network cards connected b2b

[Lokesh Chakka <lvenkatakumarchakka@xxxxxxxxx>]

hi,

I've created an Ubuntu 24.04 VM on the Ubuntu 24.04 host machine.

I want to create two NICs in the VM connected B2B for some experimental testing activity.

I've these two configuration snippets

First snippet I'm not sure where to put.

Second snippet, I'm able to understand that, I have to place it inside the devices node.

Can someone help me understand if

the attached snippets are right

and

parent node for the first snippet ?

Thanks & Regards
