Evaluating Proxmox VE as an Alternative to VMware ESXi
With Broadcom’s acquisition of VMware, many homelab enthusiasts and small to medium businesses are seeking alternatives to VMware ESXi. Today, we delve into Proxmox VE, comparing it to our once-beloved VMware. If you missed our previous video on XCP-ng, check it out here.
The Proxmox Origin Story
Proxmox was founded in 2005 by Linux developers Dietmar and Martin Maurer. Their company, Proxmox Server Solutions GmbH, has evolved into three main products: Proxmox Virtual Environment (PVE), Proxmox Backup Server, and Proxmox Mail Gateway. Proxmox VE, first released in 2008, aims to provide an easy-to-use, scalable virtualization platform managing both virtual machines and containers in a single system.
Growth and Community Support
Over the years, Proxmox VE has introduced features such as live migration, high availability, and software-defined storage and networking. A robust community supports its development, and Proxmox Server Solutions GmbH offers enterprise support subscriptions, providing professional support and exclusive repository updates.
Proxmox VE vs. VMware ESXi: Key Comparisons
Architecture
- VMware ESXi: A lightweight, type-1 hypervisor running from RAM with a closed-source kernel.
- Proxmox VE: Based on Debian Linux, it continues to use disk storage for various operational needs post-boot.
Performance
Both hypervisors offer nearly equivalent performance. However, ESXi’s limits for RAM and hosts per cluster are well-defined, whereas PVE does not specify such limits.
Usability
- VMware ESXi: Features a basic HTML5 GUI for host and VM management, with extended functionality requiring vCenter.
- Proxmox VE: Offers a built-in management interface that includes clustering, live migrations, and backup functionality without additional software.
Features
- VMware ESXi/vCenter: Requires additional licensing for advanced features like distributed resource scheduling, high availability, fault tolerance, and vMotion.
- Proxmox VE: Provides clustering, live workload migrations, high availability, and workload balancing out of the box for free.
Scalability
- VMware ESXi: Known for managing thousands of VMs, scaling clusters with vCenter.
- Proxmox VE: Supports clustering and can manage large collections of hosts and VMs, though less commonly used in very large environments.
Support
- VMware: Offers extensive professional support, training, certifications, and a well-maintained public knowledge base.
- Proxmox VE: Relies on community support but also offers professional support services at different levels through Proxmox Server Solutions GmbH.
Cost
- VMware ESXi: Recently eliminated its free hypervisor, making it less accessible.
- Proxmox VE: Free and open-source, with professional support available for a fee. Premium support is currently priced at €1020 per socket, per year.
Real-World Examples and Interface Comparisons
Both ESXi and Proxmox VE feature built-in web management GUIs. Let’s compare their consoles and management interfaces:
Console Interfaces
- ESXi Console: Provides basic host information and minimal management functionality, expecting most tasks to be managed via the web GUI.
- Proxmox VE Console: Sparse, with most management done via the web GUI, lacking a text-based menu for easier troubleshooting.
Management GUIs
- VMware ESXi: The web GUI offers a dashboard for host state, usage, and configuration, with detailed tabs for VMs, storage, and networking.
- Proxmox VE: The GUI is more complex, reminiscent of vCenter, with extensive features for host and VM management, clustering, storage, and network configuration.
Creating Virtual Machines
Creating VMs in Proxmox is straightforward, with a wizard guiding you through the process. Unlike VMware, Proxmox supports various hardware emulation options and has native TPM support for VMs.
Pros and Cons of Proxmox VE
Pros:
- Comprehensive feature set without additional costs.
- Built-in clustering, live migration, and high availability.
- Native VM backup functionality.
- Supports both VMs and LXC containers.
Cons:
- Busy and complex UI with steep learning curve.
- Constant reminders about the lack of a subscription.
- No built-in menu interface for console management.
- Complicated upgrade process.
- Lack of an easy migration path from VMware ESXi.
Conclusion
Proxmox VE presents a viable alternative to VMware ESXi, offering a feature-rich, cost-effective solution for homelab enthusiasts and businesses alike. While there are areas for improvement, its robust capabilities make it worth considering for your virtualization needs.
