If you’re working with virtual machines (VMs) or containers, you’ve probably come across Proxmox. As an open-source virtualization platform, Proxmos is based on Debian Linux and offers a complete solution for managing both VMs and containers. Although Proxmox has great virtualization features and might work for many users, it might not be the best option for others. That’s why in this blog we’ll try to find the best Proxmox alternative for your specific needs.
[lwptoc]What Is Proxmox And How Does It Work?
Proxmox Virtual Environment (VE) is an open-source server virtualization platform that can manage both virtual machines (VMs) and containers through a single, unified interface. Proxmox uses two powerful virtualization technologies: KVM (Kernel-based Virtual Machine) for running full-fledged virtual machines and LXC (Linux Containers) for lightweight containers. In Proxmox, all of this is managed through a web-based interface. So, you can configure and monitor your virtual environments directly from the web service.
This virtualizer is built on Debian GNU/Linux by using a custom Linux Kernel. With Proxmox’s open-source nature you can have full access to the source code, which means you can inspect, modify, and contribute to the project. The Proxmox software is released under the GNU Affero General Public License, which allows you to download the installer or explore the code in their public repository.
As I mentioned earlier, a key feature of Proxmox VE is its web-based central management interface. This interface is built on the ExtJS framework to provide a user-friendly experience. It supports all management tasks, including viewing task history, and system logs, and performing live migrations or setting up high availability (HA) clusters. But if you prefer working in the command line, Proxmox VE also offers a comprehensive CLI with intelligent tab completion.
Now, let’s delve into details and see how this tool works. Of course, the most significant component is the Proxmox VE hypervisor itself, which combines KVM for virtualization and LXC for containers. KVM allows you to run multiple, isolated virtual machines on a single physical server, each with its own operating system; and LXC allows you to create lightweight, isolated Linux containers that share the host system’s kernel. So, you can use it for running multiple applications without the overhead of full VMs.
Another important component of Proxmox VE is the Proxmox Cluster, which allows you to group multiple Proxmox servers together. This clustering capability is important for managing large-scale virtual environments. And you need it for features like live migration and high availability (HA). The first feature allows you to move VMs from one physical server to another without downtime and the second automatically restarts VMs on another node if one node fails to operate.
And lastly, Proxmox VE’s networking and storage subsystems play an important role in how the platform functions. The networking layer supports traditional networking as well as software-defined networking (SDN). Proxmox also integrates with various storage solutions, from local storage and NFS to enterprise-class Ceph clusters. This flexibility allows you to tailor your storage and networking configurations based on your specific needs.
Why Consider an Alternative to Proxmox?
While Proxmox is a powerful and versatile tool, it’s not without its limitations. The disadvantageous aspects of this tool may drive some users to consider a Proxmox alternative. So let’s see what drives users to find a Proxmox VE alternative.
One of the key drawbacks of Proxmox is the difficulty in managing ZFS replications or snapshots. ZFS is a robust file system and is used in enterprise environments, but Proxmox doesn’t offer a straightforward way to handle these tasks. That’s why data management on Proxmox is more cumbersome than it needs to be.
The setup process for Proxmox can also be complicated, especially when you deal with non-standard server architectures. Users often find themselves facing a steep learning curve, particularly when configuring networking or setting up advanced features. That’s because working with Proxmox requires lots manual tweaking and time-consuming configurations.
Another common frustration for Proxmox users is the repetitive nature of setting up containers or VMs for small services like dynamic DNS or VPN. While you can create your own templates to simplify this process, Proxmox doesn’t offer many pre-built templates that could be deployed with a single click from the web interface. This lack of convenience can slow down your workflow, especially if you frequently deploy similar services. Moreover, although it’s possible to template VMs with tools like Cloud-init, Proxmox doesn’t support passing a Cloud-init config file through the API. This limitation is problematic for users who rely on modern IaaS tools like Packer or Terraform.
Another area where Proxmox can pose challenges is migration. Moving virtual machines between different versions of Proxmox VE or across clusters requires extra effort and technical know-how. If migration is a routine task for you, considering a Proxmox VE alternative that offers a smooth migration workflow is a wise choice. Additionally, Proxmox lacks native support for Docker hosting, which might be a significant drawback for users who prefer containerization via Docker over other methods.
All of these factors make it clear why some users look for an alternative to Proxmox that better fits their specific needs and technical preferences.
Top Proxmox Alternatives
Now that we know about the shortcomings of Proxmox, let’s see if there are any tools out there that balance them out. Here’s a list of five Proxmox alternatives with a focus on how they address the specific shortcomings of Proxmox:
VMware vSphere
VMware and Proxmox VE are both powerful virtualization tools that have some parallel elements as well as some fundamental differences. For example, vSphere supports VMware vSAN, which integrates directly with the hypervisor to create a high-performance, distributed storage platform. This can be compared to Proxmox’s support for Ceph and ZFS, which allows for scalable storage solutions. However, they use two different virtualization technologies in their operation. VMware uses its proprietary ESXi hypervisor for running virtual machines, while Proxmox depends on KVM. A huge difference between these two hardware-assisted virtualization technologies is that vSphere excels in managing complex environments with a way more user-friendly interface and extensive documentation. Proxmox, however, requires lots of technical know-how and has a complex setup process.
[rh-cta-related pid=”25837″]Another area in which VMware can compensate for proxmox’s drawbacks is storage integration. vSphere integrates with VMware vSAN to provide a seamless experience for managing storage, especially with features like easy-to-manage snapshots and replication. This directly counters Proxmox’s limitations in managing ZFS replications and snapshots more efficiently.
We also talked about Proxmox’s dullness in handling migrations. vSphere uses a Distributed Resource Scheduler (DRS) to automatically optimize VM placement based on resource usage. So, what can be a manual and complex process in Proxmox, especially during migrations between clusters, becomes an automated task in this Proxmox alternative.

XenServer (Citrix Hypervisor)
XenServer is another reputable tool in this field that can be a reliable Proxmox alternative. While both XenServer and Proxmox use efficient hypervisors, XenServer has more out-of-the-box templates and community support for quick VM deployments. This feature can address Proxmox’s lack of pre-built templates and reduce the repetitive setup tasks that users often face in Proxmox.
Another point of comparison between these tools is XenServer’s support for Open vSwitch (OVS) and advanced network configurations. This inherent feature of XenServer simplifies complex network setups that are a huge challenge in Proxmox. This way XenServer addresses Proxmox’s complexity in networking configurations.
In environments that require high computational performance and users may want to set up PCI(e) passthrough, Proxmox only adds unnecessary complexity. XenServer, on the other hand, has robust support for GPU passthrough in a user-friendly and well-documented way.
OpenStack
Another Proxmox alternative that’s worthy of consideration is OpenStack. Just like Proxmox, OpenStack supports KVM but it has greater flexibility in scaling and managing large environments. This scalability and flexibility address Proxmox’s limitations in handling complex, multi-site deployments.
We can also compare these two tools in terms of block storage. OpenStack has a block storage service called Cinder. Cinder is a community-driven API that provides straightforward and scalable block storage management with multiple backend options. Proxmox, however, has a somewhat challenging setup for storage solutions like ZFS.
OpenStack uses an orchestration service called Heat that simplifies the deployment and management of complex cloud environments. With Heat, you can define your entire infrastructure as code using templates, which allows you to automate the provisioning of resources such as servers, storage, and networking. Proxmox, on the other hand, requires lots of manual configuration and setup effort, which might not be a serious issue for technical users but it certainly is for people with less technical skills.
Hyper-V
Hyper-V is a Microsoft product that has a Type 1 hypervisor and matches Proxmox in performance but offers a more integrated experience with Windows environments. This feature of Hyper-V addresses the lack of easy integration in Proxmox for users who are invested in Microsoft ecosystems.
Next, let’s talk about Virtual Machine Queue (VMQ) in Hyper-V. VMQ is a feature that enhances network performance by distributing network traffic directly to the network adapters on the host machine. Instead of routing all network traffic through the CPU, which can become a bottleneck in high-performance environments, VMQ offloads this processing to the hardware. So, you can be sure that data packets are handled more effectively. In contrast, Proxmox’s network setup can be more complex and may require additional configuration to achieve similar performance levels. So, if you’re a user with demanding network workloads, Hyper-V’s VMQ can provide you with better performance.
And lastly, there’s Hyper-V Replica which provides a straightforward disaster recovery solution. Hyper-V Replica allows you to easily replicate virtual machines from one host to another with continuous backups. The setup process of Replica is straightforward and requires minimal configuration. In contrast, Proxmox’s backup and restore processes are more complex and time-consuming. They also require manual effort and intense technical skills.
Unraid
Unraid uses a combination of KVM for virtual machines and Docker for containerization to offer a flexible environment for running both types of workloads. This setup is similar to Proxmox’s support for KVM and LXC containers, but Unraid’s Docker integration is more user-friendly for home labs and small-scale deployments.
Unraid has a great approach to storage management. It uses a unique RAID-like system that allows for easy expansion and mixing of different disk sizes. Unlike Proxmox, which relies on traditional RAID setups and external storage systems like ZFS, Unraid’s storage system is more flexible and easier to manage for users without extensive RAID experience.
Another advantage of Unraid is its user-friendly interface and simplicity of setup and management. While Proxmox offers more advanced features suitable for enterprise environments, Unraid’s ease of use makes it a strong alternative for users who prefer a straightforward virtualization platform.
