Deep dive into building a multi-host overlay network: VXLAN + OVS tunnels between hosts, libvirt network definitions, QEMU command-line DPDK setup with vhost-user, NUMA-aware vCPU pinning, and practical validation techniques. Designed for home lab experimentation.
I’ve spent years designing lossless Ethernet fabrics for latency-sensitive workloads. Here’s why DCBX and RoCE are the unsung backbone of everything from high-frequency trading to training billion-parameter models across GPU clusters.
Learn how to create, manage, and tune virtual machines with NUMA awareness using QEMU, KVM, and libvirt on Fedora and Ubuntu. Includes examples for NUMA topology, CPU pinning, hugepages, and bridge networking.
