Install

Harvester can be installed with the ISO image or via PXE boot.

Highlights

  • The new Branding setting allows an administrator to customize the product name, logos and color scheme. See #3396.
  • The system footprint of Harvester is reduced, better fitting Edge use cases. See #3262.
  • Automatic adjustment of ResourceQuota during migration. When migrating VMs in Harvester, the resource limit of ResourceQuota is increased based on the specifications of the target VM before migration; and automatically decreased or restored to its previous value when the migration is complete. See #3124.
  • Harvester supports adding an emulated Trusted Platform Module (TPM) to a VM. TPM is a cryptoprocessor that secures hardware using cryptographic keys and is a hard requirement of Windows 11. See #2910.
  • Harvester supports passing through SR-IOV capable network virtual functions (VFs) to workload VMs. See #2763.
  • Add rancher-vcluster(experimental) addon and bare-metal container support for the Harvester cluster. See #2679.
  • Harvester node driver(v0.6.5) supports multiple NICs and multiple disks. See #2426.
  • Harvester supports installing third-party Container Storage Interface (CSI) in your Harvester cluster to support and use external storage as the VM's non-root data disks. See #2405.
  • Enable harvester-seeder addon to configure Out-of-Band Access for a node and map the corresponding underlying hardware to a node. See #2318.
  • New installation mode supports installing Harvester to a machine without configuring the node. See #2198.
  • Introduce new Harvester cloud provider design in the guest RKE2 Kubernetes cluster and add VM load balancer support in the Harvester cluster. See #2134.
  • Harvester supports draining the node when entering maintenance mode. See #2723.
  • Harvester supports creating a VM template with data from an existing VM, including root and data disks. See #571.
  • Pod limit per node increased to 200. See #2707.

  • When you upgrade from Harvester v1.1.2 to v1.2.0, you are unable to restore an existing VM snapshot. See #3943.
  • When viewing Harvester cluster from Virtualization Management page in Rancher, project members cannot see a newly created volume from the Volumes page. See #3873.
  • When you upgrade from Harvester v1.1.2 to v1.2.0, a change in Rancher causes upgrading RKE2 to fail because the local-rke-state secret is the wrong type. See #3858.
  • When editing a Host configuration, you cannot view or edit Disk tags. See #3849.
  • When creating an RKE2 cluster, the cluster's volumes and networks differ from the final configuration. See #3786.
