SR-IOV for Intel NICs on Proxmox VE: Passing Real NIC Performance Through to VMs
virtio-net hits a wall under sustained load because every packet gets copied through a host vhost thread. Here's how to pass Intel NIC virtual functions directly into Proxmox VE guests with SR-IOV for near bare-metal throughput and latency.
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.
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.
Diagnosing GPU Passthrough Failures on Proxmox VE 9.x: IOMMU Groups, VFIO Binding, and Reset Quirks
GPU passthrough breaks in a handful of predictable ways: driver race conditions at boot, messy IOMMU groups, GPUs that won't reset cleanly, and firmware unity-map restrictions on newer hardware. Here's how to diagnose and fix each one on Proxmox VE 9.x.
Enabling SR-IOV for Network Interface Cards in Proxmox VE 9: A Complete Configuration Guide
A practical, end-to-end guide to enabling SR-IOV on Proxmox VE 9: BIOS and IOMMU prerequisites, creating and persisting Virtual Functions, and assigning them to VMs for near-native network performance.
Configuring SR-IOV Network Passthrough for High-Performance VMs in Proxmox VE
Learn how to enable SR-IOV networking on Proxmox VE to give VMs near-native NIC performance, from IOMMU setup and virtual function creation to hostpci assignment and production trade-offs.
