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.

If you prefer command-line, there are all kinds of command-line options.

I like that this is an open-source solution. It is very powerful, and it's easy.

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.

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.

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

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.

One thing that maybe could be improved is making it easier to scale. It needs to be more clear on how to scale the storage space for virtual machines.

We are not getting good support from KVM, and it is not that user-friendly.

Although KVM meets our expectations, it can be somewhat fragmented with numerous management tools available, making it difficult to determine which tool to use.

The virtual manager and the graphical QEMU for KVM need some improvement.

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.

The networking with wireless devices needs improvement.

I would like to see more focus on microservices and integration with Kubernetes or OpenShift.
