KVM Reviews

Our primary use case for KVM is our test environment. We utilize numerous servers and applications to test our core software, essential for operating mission-critical mobile networks. 

Mission-critical communication solutions support advanced push-to-talk devices, akin to 4G devices, and comply with European and US standards. We perform tests using software that runs on Linux, atop KVM. 

In production, we aim to offer these solutions to our clients, who are typically public transport companies and public safety organizations like police, fire brigades, and ambulances, as well as sectors like oil and gas and electricity companies.

KVM has benefited our organization by enabling us to assess different virtualization solutions with reduced latency, which is crucial for guaranteeing the reliability and real-time performance of our communication systems. This real-time capability of KVM enhances our capacity to deploy mission-critical solutions efficiently.

The most valuable features of KVM for us are the console, which allows us to build or clone VMs quickly, and the ability to take snapshots and recreate new VMs rapidly. That's one of the things we love about KVM.

The built-in management console, Auto KVM, is the most valuable tool for managing our virtual environments. We use it most to create and fire up new VMs or clone them for customers based on requests.

The  migration tools have worked quite well for us. We're moving from an Oracle Solaris platform for KVM logical domains, upgrading, and using KVM from Red Hat. It's slightly different but very similar to Oracle Unbreakable Linux, which is basically a clone of Red Hat. Oracle's console is easier to use than Red Hat's, though.

I think the management console has room for improvement. It could be more straightforward and user-friendly, like VMware's Console Management. This would make it easier for system admins to use and reduce training needs.

Regarding new features, we'll see when we have a chance to upgrade to a new version. We don't have any projects planned as we just upgraded to Red Hat 9.4 for some customers. Our environment is quite stable, so I don't expect any big changes until at least June next year.

We use the solution for production systems. We use it a lot in the Kubernetes environment. We are investing in microservices and Kubernetes. The tool enables virtualization.

Our whole microservice environment runs on the solution. We have quite a few Windows environments that run on it.

We use KVM for virtualization needs across various clients, allowing us to run different operating systems and machine types, including Windows and Linux. It serves as a flexible solution for creating and managing virtual environments tailored to each client's requirements.

One of the best features of KVM is its user-friendly interface.

We use KVM for virtualization. 

The tool's most valuable feature is backup. The product makes it easy to manage virtual machines. Other tools require third-party applications like VMware and vSphere. However, KVM doesn't require these applications. 

I use KVM for my data center, test environment, architecture, and integration environment.

We deploy KVM in our lab. Our use case is container deployment in a virtual machine, where we create communities. We work with containers through KVM.

What I like most about KVM is that it's very easy to use. Everything is built-in, even when writing command lines.

We are using KVM on-premises with Ubuntu 20.04 for the primary purpose of reducing operating expenses (OpEx) and to make maintenance and security easier for us. Of note, with this kind of virtualization technology, you can very easily create backups and restore data in case of disaster.

The services that we have running on our virtualized KVM environment are currently being used by everyone at the company, numbering in the range of thousands of end-users.

We also make use of Proxmox VE and, less often, VMware.

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. You don't need to go with the typical black-screen command-line interface; instead, you just have a small graphical interface with which you can create VMs, edit them, upgrade calculations, and perform other administration tasks. And, because the interface is so lightweight, it has very low memory usage.

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.
