KVM is included in the Linux kernel, which makes the use cases for KVM so much clearer. The situation for the KVM hypervisor is completely different, though. As long as Citrix stays involved, Xen technology shouldn't fall by the wayside. Citrix still offers its Citrix Hypervisor - formerly known as Citrix XenServer - a product based on open source Xen code. That's because Amazon wasn't the last big player with a commercial interest in Xen.

Looking at activity in the Xen code, it's obvious that active development still occurs, even if it's just by a handful of developers. With Amazon moving away from Xen, the Xen open source project seriously suffered, but it hasn't completely disappeared. AWS used to be one of the biggest Xen users, but the company announced in November 2017 that it would develop a new hypervisor based on KVM. Looking at activity in the Xen code, it's obvious that active development still occurs, even if it's just by a handful of developers.Įven if Xen is still alive, it's undeniable that it has lost serious ground. The reason Automotive Grade Linux uses Xen is that it supports different peripheral device virtualization methods, which offer better compliance with the safety requirements of these peripherals. Running different systems in VMs makes it possible to run the applications using just one computer instead of two. Using Xen VMs to run these applications makes it easier to create strict separation between components that are important for safety - such as the speedometer and odometer - and applications that aren't, such as the multimedia and navigation system. For example, in collaboration with the Automotive Grade Linux project, the Xen Project recently demonstrated its digital cockpit, which can host different applications in a car based on Xen VMs. It's a project under the Linux Foundation, and new releases are still being published. Let's begin with the good news for Xen Project fans: Xen is still alive. So does that mean that Xen is dead or is there still some activity for the project? Use cases for Xen

However, as of early 2019, it looks as if the battle is over and everybody is using KVM. Back in 2014, many people were talking about whether to use Xen or KVM for virtualization.
