We performed a comparison between KVM and VMware VSphere based on our users’ reviews in five categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: VMware VSphere is the winner in this comparison. It is a powerful solution with good customer support and a proven ROI. It is, however, more expensive.
"The product is really good...One can get good performance because of kernel-based virtualization."
"It offers a high-availability environment."
"It is an easily scalable solution."
"The product's scalability is good...It's a very stable product."
"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."
"The initial setup was very easy."
"There is a strong emphasis on availability, and they have numerous API interfaces for distributed storage and the solution is quite known for its openness."
"The key aspect is that the KVM directly interacts with the Kronos. There's no clear indication of indirect communication with Kronos. It is not linked to Kronos, and interaction is straightforward without any intermediaries."
"There are no issues with the level of scalability you can achieve."
"Has many good features, and is stable and reliable."
"The fact that you can use all the CPU and memory power that the server can provide is most valuable. In a physical server, you might end up not using all the physical resources. There are a lot of benefits, such as flexibility and mobility, in virtualizing computes."
"It is the number one virtualization-layer platform available, and a lot of people trust it."
"The technical support is good and they are available over the internet."
"It is a very dependable solution. Its performance is very good, and it is also easy to manage and implement."
"It's easy to use and very user-friendly."
"This solution is very stable. It's scalable and simple to set up."
"We are not getting good support from KVM, and it is not that user-friendly."
"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."
"I believe KVM offers a unified answer, while ProxMark addresses orchestration. KVM lacks orchestration. If the aim is to centrally oversee multiple KVMs – let's say to freeze them – a centralized management solution is absent."
"The networking with wireless devices needs improvement."
"We still occasionally build Interlaced Wireless Protection within our environment. The ecosystem entails areas, where we support agents, and release backup and security solutions. Collaboration with independent software vendors (ITOLs or ITOLED) is necessary to offer these solutions to customers. However, the scope of the ecosystem in KVM is not as extensive as that of VMware's. In contrast, VMware boasts a robust partner network, allowing for comprehensive customer solutions. On the other hand, KVM’s ecosystem is comparatively limited in comparison. I would like to see FT features in KVM."
"In KVM, snapshots and cloning are areas where there could be a little more sophistication, like VMware."
"The speed is around thirty percent slower than another competitor. This would be something to work on."
"The main drawback in the solution is probably disaster recovery."
"They can lower the price of its license."
"Archiving, exporting, and backing up need to be improved for this solution, because they're slower than expected."
"There are some limitations with the solution regarding migrating."
"The VMware vSphere app is faster, compared to its web-based client. The web-based client is very slow, freezes, and is challenging to use."
"When we talk about the overall private cloud stack, I would prefer for it be a lot more seamless."
"In terms of what could be improved, we do face some bugs when cloning the virtual machine - it fails sometimes."
"To manage it properly, you have to know this product really well."
"There is room for improvement in Google Cloud. The reason thing there was, like, when I type something in the terminal and then immediately, I need to go to edit the certain like file for Node.js, for the server, or for Kubernetes. So I have to do it from the terminal to the editor."
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.

Reviews from Real Users
“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
VMware vSphere is a powerful and complete server virtualization platform that allows its users to create and manage virtual data centers and machines. VMware vSphere is designed to help IT departments set up and run applications using the most cost-effective computer resources. By using vSphere, organizations save the time and energy necessary for purchasing infrastructure and software and reduce ongoing maintenance and operational burdens on IT teams.
Infrastructure administrators and network operators can access and manage the vSphere server by using a web-based cross-platform client application or via the vSphere client tool provided with vSphere.
VMware vSphere provides visibility into VMs and enables its users to carry out operations to manage VMs. This includes tasks such as:

Reviews from Real Users
VMware vSphere stands out among its competitors for a number of reasons. A few major ones are its virtualization abilities, its flexibility and availability, and its user-friendly interface.
Felix D., an Automation project administrator, DCS, I&E at Centennial Cayman Corp, writes, “The connectivity is fantastic, and many functions can run together in one server. If you need to scale, we can continue to add components or modules. It's a beautiful virtual solution that has many advantages over physical hardware, where you have to use devices and wiring to connect all your projects.”
