Configuring SR-IOV Networking for Proxmox VE 8.x Virtual Machines
A practical walkthrough for enabling SR-IOV on Intel and Mellanox NICs in Proxmox VE 8.x, from IOMMU groups and virtual function creation to hostpci mapping, VF persistence, and the pitfalls that trip up production deployments.
How to Set Up a VLAN-Aware Bridge in Proxmox VE
A beginner-friendly guide to VLANs in Proxmox VE — what a VLAN-aware bridge does, how to enable it, how to tag individual VMs, and the trunk port setting that trips up almost everyone the first time.
Configuring SR-IOV for High-Performance VM Networking on Proxmox VE 8
Virtio-net hits a wall under sustained high-throughput or latency-sensitive workloads. Here's how to enable SR-IOV on Proxmox VE 8 so VMs talk to Intel NIC virtual functions directly, bypassing the host data path entirely.
