Harvester is a cloud native hyper-converged infrastructure (HCI) open source software. Harvester was announced in 2020 by SUSE.[2][3][4]
On 1 December 2020, SUSE acquired Rancher Labs[5] who makes a product called Rancher that manages kubernetes clusters. As of v0.3.0 rancher supports integration with harvester to provide a "single pane of glass" (central web GUI) to manage both your infrastructure and workloads.
Harvester Overview
[edit]Architecture
[edit]Bare Metal
[edit]Harvester is a type 1 hypervisor designed to be deployed on bare metal servers. It can be manually installed using a ISO disk or USB install, or installed over the network via a PXE Boot server such as IPXE.
OS
[edit]Harvester uses the Elemental Toolkit to create a minimal cloud-init version of SUSE Linux Enterprise Micro 5.3 to provide an immutable Linux distribution to remove as much OS maintenance as possible.
Virtualization
[edit]Kubevirt is used on top of kubernetes to provide virtualization support. This allows harvester to run virtual machines as a kubernetes workload. Harvester provides most basic features provided by other hypervisors such as ESXi, Proxmox VE and XCP-NG / Citrix XenServer. As of v1.1.0 PCI Device passing is supported as an experimental feature, allowing PCI devices on the hypervisor host to be passed directly to a VM. Devices not in use directly by the hypervisor can be used. This is useful for passing a GPU for GPU-Accelerated Computing[6] or NVMe storage for IOPS sensitive use cases like databases.
