Resolve 'Node Not Ready' and 'Scheduling Disabled' states in Harvester HCI. This diagnostic guide covers Longhorn engine failures, CSI timeouts, and ResourceProfile mismatches.
Explains why Harvester bundles Longhorn as the default storage backend for VM disks, outlines the minimal design, trust boundaries, verification steps, and failure-mode mitigations.
Harvester live migration moves a running VM between nodes without shutdown, but only if shared storage, CPU compatibility, and network capacity are in place. Here is how it works and how to test it.
Decide between Harvester live migration and cold migration by reviewing storage, CPU, network constraints, trade‑offs, and a step‑by‑step validation guide.
Live migration in Harvester is a storage and capacity decision before it is a UI action. Learn the Longhorn prerequisites, KubeVirt migration checks, and a repeatable node-maintenance runbook.
Need to patch a Harvester node without killing VMs? Live migration moves VM memory between nodes using KubeVirt and shared storage, but only with compatible CPUs and no device passthrough.
Use Rook‑Ceph RBD with Harvester to give VMs distributed, highly available block storage. This guide walks through deployment, provisioning, and trade‑offs.
Harvester live migration moves running VMs between nodes using Longhorn storage and Calico networking, but device passthrough, hostPath volumes, and custom CPU models block it. Learn how to check eligibility, trigger migration, and verify zero‑downtime success.
An architecture note covering Harvester’s integrated KubeVirt and Longhorn design: requirements, minimal viable layout, trust boundaries, operational checks, failure modes, and redesign triggers.
