We performed a comparison between Hyper-V and KVM based on our users’ reviews in four categories. After reading all of the collected data, you can find our conclusion below
Comparison Results: Hyper-V is the clear winner in this comparison it is easy to install, robust and high performing. Hyper-V, as a Microsoft product, also offers stable and ongoing customer support.
"For me, the setup of Hyper-V was an easy process, which took only one hour from start to finish."
"My understanding is it's easy to set up."
"The restore function of the virtual server is valuable to me."
"It is an affordable platform."
"The virtualization aspect of the solution functions similar to VMware is one of its most valuable features…It is a stable product."
"The solution is stable."
"I like the functionality."
"The solution is very user-friendly."
"It is an easily scalable solution."
"It offers a high-availability environment."
"The most helpful aspect of KVM is the fact that the interface is so minimal. It includes just what you need to set up the VMs and manage them, and it's very simple to do so."
"I have found KVM to be scalable."
"The most valuable feature is hypervisor. I can host at the same time different operating systems in Linux Windows."
"Documentation and problem-solving troubleshooting are the most valuable features. Performance (when fine-tuned and with "special" HW) is awesome, equal to or more than other enterprise closed-source solutions."
"The initial setup was very easy."
"The product's scalability is good...It's a very stable product."
"Hyper-V doesn't have a lot of features and is limited compared to other virtualization software."
"The biggest problem with Hyper-V is that the virtual machines are mostly running on top of the Windows Server, so we often need to reboot the machine and virtual machines when updating the host level. That's why we prefer VMware. It's much easier to patch the host. Also, Hyper-V has security vulnerabilities. It's easy to attack and compromise the host."
"Hyper-V requires improvement with manageability."
"The solution should improve its native integration with other public cloud solutions."
"The weakness of Hyper-V is in its interaction with iSCSI protocols."
"The management of Hyper-V could improve, there is a lot to improve in that area."
"Hyper-V could improve the management tools."
"The only negative thing I heard was that the baseline price is very, very attractive relative to VMware, however, the vCenter counterpart, the thing that brings it all together, is quite pricey."
"KVM is very difficult to manage and run on daily operations."
"The speed is around thirty percent slower than another competitor. This would be something to work on."
"In KVM, snapshots and cloning are areas where there could be a little more sophistication, like VMware."
"The grid interface of KVM needs improvement. It could be more beautiful, especially when compared to VMware."
"The main drawback in the solution is probably disaster recovery."
"We are not getting good support from KVM, and it is not that user-friendly."
"The networking with wireless devices needs improvement."
"One problem I have is that it's not very scalable when it comes to resizing the VM disk dimensions. For example, if you have initially set a virtual drive to 10 GB and you want to upgrade it to 15 GB, it's not that easy."
Hyper-V is a hardware virtualization tool that allows users to create virtual computer environments with multiple operating systems on a single physical server. Each virtual machine has computer parts, such as memory, processor, storage, and networking, and acts like a standard computer - running its own operating system and software programs. Each component of the virtual machine can be configured to meet your specific requirements.
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 machine or server. Each virtual machine runs in its own isolated space, which means you can run many virtual machines simultaneously but independently of each other. This helps prevent problems such as a crash affecting the other workloads and enables different users to separately access various systems.

Reviews from Real Users
Hyper-V stands out among its competitors for a number of reasons. Several major ones are its flexibility, its replication capabilities, and the fact that its virtual machines utilize a small amount of resources..
Liam L., the owner of a tech services company, writes, “It is actually very low on resources. It doesn't use many resources. It is also very easy to tailor. You can change things like the amount of memory and storage on the fly. It is very stable and reliable. I like its replication feature, which is very good. It is also very easy to move the virtual machines across push servers without any difficulty. Its performance is also very good. Now with this pandemic, a lot of workers are working from home. A lot of workers have been using laptops as their desktop computers, and they would remote into a virtual PC. There is no difficulty, and they can't tell the difference between this and the real one. It is much easier to manage.”
Kevin E. an IT director at Homeland Technology Group, LLC, notes, “We've probably seen a 50 percent speed increase on our SQL server. Hyper-V has also significantly reduced our downtimes with faster boot-up and reboot. If we have to reboot a server, there is maybe two or three minutes of downtime. When we were on a bare-metal server, it could be five to ten minutes due to the total boot time.”
KVM stands for Kernel-based Virtual Machine, which is an open-source virtualization technology that is embedded in Linux. KVM allows users to seamlessly transform their Linux system into a hypervisor that, in turn, will enable a host machine to run numerous, isolated virtual environments or virtual machines (VMs).
KVM is part of Linux. Users with Linux 2.6.20 or newer already have KVM. As KVM is already a component of the current Linux code, it automatically improves with every new Linux fix, feature, or upgrade. So KVM users are always current and up to date.
KVM automatically transforms Linux to a type -1 (bare-metal) hypervisor. All hypervisors need operating system components, such as a process scheduler, I/O stack, device drivers, memory manager, and more, to run a VM. KVM already has these components embedded, as it is part of the Linux kernel. Each VM is generated as a basic Linux proces,s which is maintained by the standard Linux scheduler, with dedicated hardware such as a graphics adapter, memory, disks, network card, and CPUs.

“The most helpful aspect of KVM is the fact that the interface is so minimal. It includes just what you need to set up the VMs and manage them, and it's very simple to do so. KVM, as a native virtualization solution, is a complete and fully adequate system for small businesses that need to reduce costs, and also to make maintenance easier. “ - Georges E., Business Engineer and Consultant at All-Tech
“The most valuable feature of KVM is the hypervisor environment and how we can configure it with ease. Additionally, the interface is intuitive.” Sonu S., Senior Solution Architect at Micro Focus
