"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.""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.""Lacks high availability across clusters as well as support for Apache CloudStack.""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.""Monitoring and resolution could be improved.""Business continuity features need to be added.""Its resource usage can be improved.""There are some issues with the graphics and some software that is very complex."

More KVM Cons →

"The user interface needs to be improved.""The AI and the UI could be improved. The user interface is a little outdated and the AI is not very attractive.""Having live migrations to move a running server to other hardware would be great.""Basically, the GUI and command-line interface need improvement.""It would be good if we could use Hyper-V Windows subsystems with Linux and VirtualBox on the same instance. Currently, to be able to use VirtualBox, we have to restart the machine into an instance of Windows where Hyper-V is disabled, which is understandably very inconvenient.""When I select the Ubuntu operating system from within the virtual machine, it sometimes hangs.""The installation is difficult and could be improved.""Oracle VM VirtualBox is not flexible, It's not like VMware."
