Featured Review
Quotes From Members
We asked business professionals to review the solutions they use.
Here are some excerpts of what they said:
Pros
"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.""If you prefer command-line, there are all kinds of command-line options.""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.""This solution is open source and easy to configure.""Good screen and keyboard sharing feature.""The GUI interface makes the management of KVM easier than ever before.""Very cost-effective.""I have found KVM to be scalable."

"Oracle VM VirtualBox is easy to use.""I like that it is free and runs on Linux/Ubuntu - I wouldn't use any other solution. I am able to perform small developing tests.""It is easy to use and does not require complex knowledge.""The installation is easy.""This product is very user-friendly and easy to use.""It's a pretty good product in terms of monitoring.""Technical support is good.""Oracle VM Virtualbox is easy to use and does not require much training."

Cons
"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.""There are some issues with the graphics and some software that is very complex.""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.""Lacks high availability across clusters as well as support for Apache CloudStack.""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.""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 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."

More KVM Cons →

"Basically, the GUI and command-line interface need improvement.""The installation is difficult and could be improved.""The memory and hardware usage could be a little bit lighter. Right now, it's quite heavy on the usage. The CPU usage should be lower.""There are a few bugs that need to be updated.""It has some issues when you have some weird device drivers. For instance, when you have a weird sound driver working on your machine, and the VirtualBox needs to output the sound of the virtual machine into the sound driver of the physical machine, the bare metal, it doesn't work too well. If you tweak lots of drivers and play around with the different kinds of drivers and machines, you will probably break something. I have not played with it too much and maybe it already supports it, but it would probably be good to have the ability to use a container from the virtual machine environment instead of spinning off a complete virtual machine. There are other tools for that. On Linux, you have a DXE, LXC framework, and you have Docker as well. Docker is good because it is multi-platform, and you can run Docker on pretty much anything, even different processors, but it would be good if we had a VirtualBox running on it while spinning off containers instead of full virtual machines. The other thing that will become important, and I'm pretty sure that they are thinking about it as well is that there's this new hardware platform that Apple is releasing, which is an ARM-based new chip. So, VirtualBox will probably have to work on ARM-based CPUs as well.""The AI and the UI could be improved. The user interface is a little outdated and the AI is not very attractive.""The user interface needs to be improved.""I find the solution to be incredibly unstable, constantly falling over and not working properly."

Pricing and Cost Advice
  • "It is free for everyone."
  • "The price is fair compared to others. But in our local market, it's a problem to get budget approval from management. That's why they are trying to get those products so we can give them the price benefit. But if you consider the international market or other products, it's sometimes better than their price."
  • "We had some problems with the licensing."
  • "KVM is priced reasonably."
  • "There is no cost involved in the use of KVM, as it is open source."

  • "There are no licensing fees."
  • "The license I use is free."
