Virtualization is at the core of many of today's enterprise IT environments -- with at least 70% of x86 server workloads virtualized, according to Gartner -- so the hypervisor plays an important role. And while most hypervisors look similar at first glance, the details can make a significant difference. Learning where and when each hypervisor is the best choice can provide your organization with increased efficiency and cost savings.
If you're new to virtualization, a hypervisor is a program that allows multiple operating systems to share a single hardware host in a way that each operating system appears to have the host's processor, memory, and other resources. The hypervisor does this by creating and running multiple virtual machines.
There are two main types of hypervisors. Type 1 hypervisors run directly on the host's hardware to control the hardware and to manage virtual machines. These are often referred to as "native" or "bare-metal" because they require no other underlying operating system. Type 1 examples include VMware vSphere ESXi hypervisor, Citrix XenServer, and the open source KVM (Kernel-based Virtual Machine).
Type 2 hypervisors are hosted, which means they must run inside an operating system that, in turn, is running on the physical hardware. Type 2 hypervisor examples include VMWare Workstation and Oracle VM VirtualBox.
Our researchers compared the features of the top hypervisors in the market, which all happen to be Type 1: Microsoft's Hyper-V hypervisor, VMware's vSphere ESXi hypervisor, and KVM. Hyper-V and vSphere have the highest deployment rates, and KVM has several large backers and a great deal of support from the open source community.

Virtualization is at the core of many of today's enterprise IT environments -- with at least 70% of x86 server workloads virtualized, according to Gartner -- so the hypervisor plays an important role. And while most hypervisors look similar at first glance, the details can make a significant difference. Learning where and when each hypervisor is the best choice can provide your organization with increased efficiency and cost savings.
If you're new to virtualization, a hypervisor is a program that allows multiple operating systems to share a single hardware host in a way that each operating system appears to have the host's processor, memory, and other resources. The hypervisor does this by creating and running multiple virtual machines.
There are two main types of hypervisors. Type 1 hypervisors run directly on the host's hardware to control the hardware and to manage virtual machines. These are often referred to as "native" or "bare-metal" because they require no other underlying operating system. Type 1 examples include VMware vSphere ESXi hypervisor, Citrix XenServer, and the open source KVM (Kernel-based Virtual Machine).
Type 2 hypervisors are hosted, which means they must run inside an operating system that, in turn, is running on the physical hardware. Type 2 hypervisor examples include VMWare Workstation and Oracle VM VirtualBox.
Our researchers compared the features of the top hypervisors in the market, which all happen to be Type 1: Microsoft's Hyper-V hypervisor, VMware's vSphere ESXi hypervisor, and KVM. Hyper-V and vSphere have the highest deployment rates, and KVM has several large backers and a great deal of support from the open source community.

No love for Xen, eh?
Incidentally, is it still proper to consider it the "Citrix XenServer" when the company donated the Xen hypervisor to the Linux Foundation two years ago?

Joe, we didn't include Xen because its market share is only at 3% and is growing smaller, which it has been since Citrix stopped supporting the enterprise server version. I am gussing that's the reason for decline, and probably why people still call it "Citrix XenServer" even if that may be officially incorrect ;).

Thanks for the explanation, Susan! I'm surprised that its market share has been shrinking; a couple of years ago, it seemed potentially well-poised to steal market share upon the donation to the Linux Foundation. But, of course, when companies stop offering support, that's what happens...

@Susan That's interesting to hear regarding Xen but maybe not surprising. From what I recall it seem to be rather complicated to get up and running.
Maybe I just didn't have the knowledge base for it - I encountered it at least 10 years ago via a brief Web Hosting assignment.

@Joe Xen was the first Hypervisor I had ever heard of. I am thinking KVM is similar ?

@ClassC: Well, they're both open source -- except whereas Xen was a Citrix product and has since been donated to the Linux Foundation, KVM squarely remains a Red Hat product.

@Joe I see. I did not know Xen was from Citrix originally and thanks to you and the guide - I now understand KVM is a Red Hat offering.
Thanks.

@Joe Stanganelli,
Actually, I think you'll find that KVM (part of the Linux kernel) is squarely 'Open Source' and is provided as a standard component of all major Linux distributions including SUSE's and Canonical's.
It should also be noted that Citrix and Microsoft have/had a strong relationship and much of Hyper-V is based on XenServer, it is apparent that Citrix is willing to sacrifice the server platform to Microsoft and Hyper-V in order to grow its desktop virtualization business. OracleVM is also based on Xen.

I rather took Citrix's move to donate Xen to the Linux Foundation as a way to focus more on and help attract more customers to its desktop virtualization business, positioning itself as an open-source supporter while cozying up to other Xen Project heavies.

I really enjoyed this Guide to Hypervisors. There is a great deal of information to aid Engineers and Admins in increasing their understanding of the subject.
In my area (Los Angeles) I am starting to see many opportunities for those experienced in virtualization and as a result I am starting to take the study much more serious than I ever have as an engineer.
I worked in a atypical tech environment for many years ( where virtualization was not an viable option ) but now that I am returning to consulting, the need to understand virtualization has taken on an added importance and I am in a race to catch up !
Thank you Network Computing for providing this resource. It really helps.

Very glad it's helpful ClassC! Virtualization definitely has become mainstream. Storage virtualization seems to be still emerging, but industry experts are pretty excited about the VSAN and Virtual Volumes technologies VMware released last week with vSphere 6. We'll have some blog posts on that soon.

Storage virtualization is really promising, this is an area I can really use, as I have clients with large data requirements.
This looks to be the first area of concentration for me.

Just to set the record straight. https://en.wikipedia.org/wiki/Xen
History
Xen originated as a research project at the University of Cambridge, led by Ian Pratt, senior lecturer at Cambridge who co-founded XenSource, Inc. with Simon Crosby also of Cambridge University. The first public release of Xen was made in 2003.
Xen has been supported originally by XenSource Inc., and since the acquisition of XenSource by Citrix in October 2007. This organisation supports the development of the free software project and also sells enterprise versions of the software.
On 22 October 2007, Citrix Systems completed its acquisition of XenSource,[4] and the Xen project moved to the xen.org domain. This move had started some time previously, and made public the existence of the Xen Project Advisory Board (Xen AB), which had members from Citrix, IBM, Intel, Hewlett-Packard, Novell, Red Hat, Sun Microsystems and Oracle. The Xen Advisory Board advises the Xen project leader and is responsible for the Xen trademark,[5] which Citrix has freely licensed to all vendors and projects that implement the Xen hypervisor.[6]
Citrix has also used the Xen brand itself for some proprietary products unrelated to Xen, including at least "XenApp" and "XenDesktop".
On 15 April 2013, it was announced that the Xen Project was moved under the auspices of the Linux Foundation as a Collaborative Project.[7] The Linux Foundation launched a new trademark for "Xen Project" to differentiate the project from any commercial use of the older "Xen" trademark. A new community website was launched at xenproject.org[8] as part of the transfer. Project members at the time of the announcement included: Amazon, AMD, Bromium, CA Technologies, Calxeda, Cisco, Citrix, Google, Intel, Oracle, Samsung, and Verizon.[9] The Xen project itself is self-governing.[1
