Overview

Hanzo VM is an open-source cloud operating system and virtual machine management platform built with Go (Beego framework) and React. Go module github.com/hanzoai/vm, ships as a single server binary with a bundled web frontend. Manages VMs across multiple cloud providers (AWS, Azure, GCP, Alibaba, Tencent, DigitalOcean) and local hypervisors (libvirt, Proxmox). Authenticates via Hanzo IAM (Casdoor). License: Apache-2.0.

Why Hanzo VM?

Multi-cloud: AWS EC2, Azure, GCP, Alibaba, Tencent Cloud in one dashboard

Local hypervisors: libvirt (KVM/QEMU) and Proxmox VE support

Hanzo IAM integration: SSO via Casdoor, Casbin RBAC authorization

RDP/SSH tunneling: WebSocket-based remote desktop via vmd (Guacamole daemon)

Blockchain records: On-chain VM operation audit trail (chain/ package)

React frontend: Full web UI for VM lifecycle management

Tech Stack

Backend: Go 1.26, Beego web framework, XORM (ORM)

Frontend: React, Node.js 18, Yarn

Database: PostgreSQL (default), MySQL, or any XORM-supported DB

Auth: Hanzo IAM (Casdoor Go SDK), Casbin RBAC

RDP: vmd (Guacamole daemon, ghcr.io/hanzovm/vmd)

Image: Multi-stage Docker (standard + all-in-one with MariaDB)

OSS Base

Repo: hanzoai/vm (Casvisor fork). Default branch: master.

When to use

Manage VMs across multiple cloud providers from a single dashboard

Self-hosted cloud management with IAM integration

Remote desktop access to VMs via browser (RDP/SSH tunneling)

Audit trail for VM operations with blockchain records

Local KVM/libvirt or Proxmox VM management

Hard requirements

PostgreSQL (or MySQL) database accessible

Hanzo IAM (Casdoor) instance for authentication

Go 1.21+ for building from source (or Docker)

Node.js 18 + Yarn for frontend build

Module Replacement

The go.mod includes a notable replacement:

replace github.com/casdoor/casdoor-go-sdk => github.com/hanzoid/go-sdk v1.44.0

This uses Hanzo's fork of the Casdoor SDK for IAM integration.

Troubleshooting

Issue	Cause	Solution
Login fails	IAM not reachable	Verify `iamEndpoint` in app.conf, check Hanzo IAM is running
DB connection error	Wrong dataSourceName	Check PostgreSQL host/port/user in `conf/app.conf`
RDP not working	vmd not running	Start vmd container: `docker run -d -p 4822:4822 ghcr.io/hanzovm/vmd`
Cloud provider errors	Wrong credentials	Verify cloud provider credentials in provider configuration
Frontend 404	Build not run	Run `cd web && yarn build` to generate `web/build/`
Session expired	Redis not configured	Set `redisEndpoint` in app.conf or accept file-based sessions
