Xen and KVM - Who is using what and why?

@FATeknollogee said in Xen and KVM - Who is using what and why?:

Saying one moved to Scale because it's KVM is like saying I moved to Nutanix because it's KVM!

Let me re-phrase the question: Was the move to Scale done because it was technically superior to XS or was it financially motivated?

The challenge for both Scale and Nutanix is that KVM REALLY isn't the reason as they don't expose the native KVM API's and so products that would layer on top of KVM (Cloud Forms, vRealize Automation etc) are effectively broken unless re-written for their own proprietary API's. (In Scale's case with target customers and market this doesn't really matter in Nutanix's case this leads customers with heavy interop with other things like CMP, to end up running vSphere for the most part).

In this regard a reason someone might choose KVM (Open Platform) or Xen (Public robust API's) actually is the LAST reason you would choose Scale/Nutanix as they are more difficult to interact with from 3rd party tools than a AS400

KVM with Virtmanager.
Centos latest is my preferred KVM host.
And Fedora LXDE Spin is my preferred Virt-Manager choice, I use it from inside Windows using Virtualbox.

Cause it resembles the old ESXi Philosophy with Vsphere C# client
And you can do whatever you want with it, and for free. Especially when you use virt IO drivers for network and disk, you get nearly identical bare metal speeds.

But sadly its lacking other tools to allow users to connect and use the VM, you will have to do this from inside the VM like RDP and VNC.
