We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
I think the cluster environment is a good feature of Hyper-V because, if something happens, then it will automatically move to some other mode. This is a great feature of the solution.The setup was straightforward and easy for our company. The deployment was fast.It is easy to use, and it is stable. It is a good solution.It utilizes the hardware so there are multiple applications running on one hypervisor.It is a stable product.It allowed us to add on servers and fix things in an expedient manner.I think all of these improvements are going in a good direction. For me, its direction is good and I'm very satisfied with this product.The flexibility and API are the most valuable features. It helps us be able to integrate with other systems and then push data easily.

I find the density of the product most valuable. It is density that a technologist can just assign page merging. This is what makes KVM one of the important players of the virtualization market.The initial setup was simple.It is an open ecosystem, and we see there is a benefit in open-source solutions.I think nine out of the ten supercomputers in the world use Linux KVM, so I think that attests to the fact that it is a scalable product.KVM has a rich options set which can be directly used or via wrappers, such as libvirt.If you are a Linux desktop user, KVM is the solution to go with if you have to start virtual machines with Linux or other operating systems with almost zero extra configuration needed.A very reliable solution which can be used for x86 architecture virtualization with reasonable overhead.

Cons
Sometimes it is a mess, and it is getting hanged. It should be something that could be easily fixed. It made us have to deal with fixing the bugs.In my opinion, read the documentation carefully. If you do not, you will have problems.I think there is room for improvement in terms of the cloud solutions.There are bugs, and this should be resolved by Microsoft.Microsoft tech support is horrible.I am using this solution with E-Notes. I heard that there will be future improvements in integration of the E-notes systems. This would be very helpful.The interface could be more user friendly. In addition, the documentation and security could use improvement.It needs to improve compatibility with third party software.

The stability of this solution is less than other products in the same category.The KVM tech support is really bad. They are not very responsive.We would like to have a software lifecycle solution included in this solution. We can handle the software needed for KVM, but also the software that we provide. A lifecycle component would be very beneficial.Technical support is not top-notch.The only negative aspect of needing hardware support is a fully functional KVM can be dropped. It would be nice if the support for other platforms, like ARM or Risk, were as good as the x86 one. However, with the democratization of Chromebooks based on these chips and mobile devices, it will not take long for that to happen.

Pricing and Cost Advice
The pricing is not much. We have a very big environment, and pricing is no problem.The pricing and licensing is pretty good.I think it is expensive. I think if they want it to be more competitive, they should lower the price.The pricing and licensing is fine.The Hyper-V pricing and licensing are very good.We previously used VMware, but we switched because Hyper-V is cheaper and delivers the same stability for less money.The pricing is not an issue for us because we have a licensing agreement with Microsoft. So we are given an 80% discount.I do not have experience with pricing or licensing of the product.

This solution came with the Linux license.It is cheaper than other solutions out there on the market.It is cheaper than other competitors like VMware or Hyper-V.​It is free and can be run from your laptop, if needed, unlike VMware.​

Microsoft Hyper-V:

Microsoft introduced its hypervisor in 2008, and has continued to release new versions along with the new Windows servers. Hyper -V helps one expand or establish a private cloud environment, promotes effective hardware utilization, improves business continuity and makes development and testing more efficient. We have discussed some features for Windows Server 2019 here.
Features:
Persistent memory support.
Shielded VM updates.
Simple Two-Node clusters.
ReFS Deduplication.
Storage Spaces Direct improvements.
Windows Admin Center.
Encrypted subnets.

KVM (Kernel-based Virtual Machine):

KVM is a complete virtualization infrastructure solution. Kernel-based Virtual Machine turns Linux kernel into a hypervisor. A part of Red Hat Virtualization suite, it was merged into the Linux kernel mainline in kernel version 2.6.20.

Here is an overview of the features of KVM:

Scalability.
Overcommit resources.
Disk I/O throttling.
Hot plug of virtual resources.
Low cost virtualization solution.
Use API.
Live Migration & Storage Migration.
Assign any PCI device to virtual machines.
Container support.
Disaster Recovery support.

KVM is very fast & very stable & low cost.

The tooling around Hyper-V is more advanced than around KVM,

Speed wise, setting up and managing the virtual machines appear easier in KVM than in Hyper-V especially for remote servers on slow connections.

Best regards.

Overview

Hyper-V is a native hypervisor for x86-64 systems, enabling platform virtualization. It is a Microsoft product that comes in two forms. One form is Hyper-V as a standalone product, known as Hyper-V Server (Hyper-V Server 2012 R2 is the latest version). The other form is as a role to be installed in Windows Server 2008, Windows Server 2008 R2, Windows Server 2012, Windows Server 2012 R2, or the x64 version of Window 8 Pro. No matter what form it takes, Hyper-V gives you the services and tools required to create a virtualized server environment.

Hyper-V creates a cost-effective, stable and productive server virtualization environment by running multiple operating systems, such as Windows, Linux, and more, in parallel on one server.

Some of the business benefits of installing Hyper-V include:

  • Create a private cloud environment or expand an existing one.
  • Optimize hardware utilization and minimize resource consumption by consolidating servers in the form of virtual machines on one physical host.
  • Improvement of business continuity.
  • Virtual Desktop Infrastructure creation or expansion.
  • Greater efficiency for test and development activities.

KVM (for Kernel-based Virtual Machine) is a full virtualization solution for Linux on x86 hardware containing virtualization extensions (Intel VT or AMD-V). It consists of a loadable kernel module, kvm.ko, that provides the core virtualization infrastructure and a processor specific module, kvm-intel.ko or kvm-amd.ko.
