Alternative to VMware: what Hypervisor to choose?

Xen Orchestra

Are you an IT Manager looking for a comprehensive solution to manage your virtual machines? 

Are you disappointed by VMware’s new licensing and you are searching for alternatives?

Well, you are in the right place.

We know that most companies have always relied on VMware ESXi solution for virtualizing large and small data centers. With Broadcom’s acquisition of VMware, users have begun to grow impatient and have started to carefully consider alternatives.

In this article, we will explore XCP-NG in detail and how this Hypervisor could be an excellent answer to this search.

We will discover the main features of Xen Orchestra, the management platform for XCP and XenServer, its advantages and how it can be integrated into your IT environment to improve operational efficiency and the security of your virtual infrastructure.


XCP-NG stems from the XEN Source project (, the Hypervisor of the Linux Foundation. From Xen Source, Citrix created Xenserver, Amazon created its Hypervisor for AWS, and Vates created XCP-NG. Today, the heart of the entire Xen project is under, which is still part of the Linux Foundation. Since 2014, the VATES group in Grenoble has developed Xen Orchestra initially for XenServer and then realized the XCP-NG fork, designed to scale not only for enterprises but also for cloud and high-performance computing.

What is Xen Orchestra?

Xen Orchestra is a comprehensive hypervisor management platform that surpasses the simple functionalities that a sysadmin expects. Xen Orchestra deals with the entire lifecycle of hypervisor and virtual machines, providing a plethora of features, including:

  • VM host live migration
  • VM storage live migration
  • Automatic hypervisor patching and upgrade
  • Web-based management console
  • Full virtual machine management
  • API
  • Snapshot
  • Upgrade
  • Backup and restore
  • Disaster recovery

Basically, Xen Orchestra is a true management interface for your virtual infrastructure that operates in 4 specific areas:

  • Administration and management
  • Backup & Disaster Recovery

  • Cybersecurity

Xen Orchestra is both a web application and API-based, an agentless solution that includes all the features you need, from hot migration to virtual machine replication, with little more than a click.

In essence, Xen Orchestra handles everything above the hypervisor environment, supporting the two main hypervisors: XenServer and XCP-ng. 

This is why it is highly sought after by those wanting a valid alternative to VMware solutions.

Advanced Features of Xen Orchestra

The list of Xen Orchestra tasks is long, and it can be consulted on the producer’s website in a very simple table. Among all the features, some are quite appreciated by customers.  Let’s see them together because they can make a difference in virtual machine management processes:

Xen Orchestra’s Strength? The Advanced Backup Management

What layer is added to the hypervisor through Xen Orchestra?

What does this layer do to the Hypervisor?

A Hypervisor without a management interface has a limited set of functions. 

Backups can be performed, but their execution won’t be efficient for those carrying it out, update procedures won’t be as quick, and you’ll be forced to interact through command lines. 

As such, those accustomed to working in a VMware environment use VMware Virtual Center, which, however, requires an additional component if you want to perform advanced backups and have advanced restoration functionalities, hence the utility of software like Nakivo and Veem. 

Just as ProxMox was born for the KVM Hypervisor, Xen Orchestra is the management environment for XenServer and XCP-ng. 

With Xen Orchestra, you can configure hosts in pools with each other, then point them to a common SAN, create plans for continuous replication, local or even remote disaster recovery, perform live migration between hosts and SANs. 

These features of Xen Orchestra are highly appreciated even by small businesses for obvious reasons like practicality and costs.

With its large number of functionalities and support for XCP-ng and XenServer, it offers a simple and efficient way to manage and protect the virtualized IT environment.
