In a high-configuration Proxmox VE hyperconverged cluster, to make full use of resources, virtual machines need to be isolated by network based on specific requirements, to support larger-scale scenarios.

In a previous article, we used SDN’s Simple mode to implement network isolation for tenants (users), but it has a limitation: communication can only occur within a single physical node and not across multiple physical nodes (unless special handling is…

Proxmox VE 8 integrates an easy-to-operate SDN function plugin in the Web management backend. Essentially, it assigns different networks to different PVE users, providing logical isolation and avoiding conflicts caused by different users setting the same network address.
