SDN implementation

[muditha]

need to implement SDN in Proxmox environment. Currently, all the VMs are using physical adapters. Will implementing SDN have any impact on the currently running VMs and network?

Normally no. SDN adds additional adapters but leaves existing ones alone.
Technically an include file "sdn" in "/etc/networking/interfaces.d/" will be created.

Yes that's right, you as Administrator must give new SDN names for adapters, in the simple network case you get the setup as source Network translation. So no LXC or VM can access from outside the Proxmox host.
