Harvester, the open source hyperconverged infrastructure platform built on Kubernetes, has released version 1.7.1-rc4 for testing. This release candidate addresses numerous upgrade path issues that plagued earlier versions, particularly problems moving from v1.6.x to v1.7.0 where kubeovn-operator upgrades would stall and longhorn-manager image mismatches caused installations to hang.
The pre-release is available for both AMD64 and ARM64 architectures, with full ISO and net install options for AMD64 systems. Key fixes include resolving addon-managed DHCP failures, correcting VM boot issues when created from templates, and addressing raw image upload problems with external storage. The team has also fixed a bug where VMs would unexpectedly shut down during migrations and resolved host IP address changes that occurred when using DHCP during upgrades.
Underneath, Harvester 1.7.1-rc4 bundles KubeVirt v1.6.3, Longhorn v1.10.2 for distributed storage, Embedded Rancher v2.13.1, and runs on SLE Micro 6.1. The Rancher team explicitly warns that this is a testing release only, with no supported upgrade path to or from this version.
