This guide explains the prerequisites, step‑by‑step procedures, and command‑line options for both cold and live migration of KVM virtual machines using NFS‑based shared storage, highlighting common pitfalls such as service interruption and MAC address conflicts.
This guide explains how to perform both cold and live migration of KVM virtual machines using NFS shared storage, covering prerequisites, step‑by‑step commands, network considerations, and key virsh options to avoid disk corruption and ensure seamless VM movement across hosts.
This article details the design, implementation, and results of migrating over 16,000 virtual machine disks from an aging Ceph Luminous cluster to a high‑performance mixed‑flash Ceph cluster using QEMU QMP hot‑swap, achieving a 47.65% reduction in IO latency and enabling cost‑saving decommissioning of legacy storage.
