KVM pros and cons

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.

The GUI interface makes the management of KVM easier than ever before.

I like that it's easy to manage. It's also more powerful when it comes to security than others. That point of view is the one consideration. The other consideration is that it's cost-effective.

Very cost-effective.

This solution is open source and easy to configure.

KVM is stable.

It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox.

I have found KVM to be scalable.

Good screen and keyboard sharing feature.

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.

Business continuity features need to be added.

Technical support could be better. In the next release, I would like to see an improved user interface and dashboard. This type of improvement will make it easy or help our engineers understand the solution from a requirement point of view.

Lacks high availability across clusters as well as support for Apache CloudStack.

There are some issues with the graphics and some software that is very complex.

In our setup, we do not have any dashboards or orchestration, and it is hard to manage. We have 25 gig network cards, but the software driver we have only supported 10 gigs.

Its resource usage can be improved.

I have previously used VMware and KVM is easier to use. However, they both have their strengths depending on their use cases. They are mostly equal. One of VMware's advantages is it has better support.

Monitoring and resolution could be improved.
