Quotes From Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
"I find the density of the product most valuable. It is density that a technologist can just assign page merging. This is what makes KVM one of the important players of the virtualization market.""The initial setup was simple.""Our production servers are running in Linux, and this solution supports that environment well.""Scaling the solution is easy. You just have to add more hardware.""I like that this is an open-source solution. It is very powerful, and it's easy.""The GUI interface makes the management of KVM easier than ever before.""The KVM service is well managed with a central policy interface.""If you prefer command-line, there are all kinds of command-line options."

"The scalability of the solution is very good.""The most valuable aspects of the solution were the support and performance of the product and the flexibility it gives you to work.""The solution's most valuable feature is its stability.""I think VirtualBox has good stability because I use it in an environment with several resolutions.""The solution is very stable.""The initial setup was straightforward.""This solution can be used on many different platforms including Windows and Linux.""The most valuable feature is the ability to copy bidirectionally between the desktop and the virtual machine."

Cons
"The stability of this solution is less than other products in the same category.""The KVM tech support is really bad. They are not very responsive.""Support for VF is needed, where you can, for example, export from VMware to KVM.""The solution should be more user friendly. We are struggling with the command lines.""The virtual manager and the graphical QEMU for KVM need some improvement.""Business continuity features need to be added.""The initial setup of this solution is more difficult than some of the competing products and it could be improved.""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."

More KVM Cons »

"The solution should work to simplify the system. However, it should be flexible enough to allow for special cases.""The solution has to do a better job of promoting the product and its licensing capabilities.""Oracle needs to improve its hot virtual machine migration. It didn't work as intended. It should allow us to migrate between virtual machines, without stopping the database.""The technical support needs to improve.""The solution should have more enterprise features, like migration, high availability storage, disaster recovery, and the ability to deploy to enterprise-scale usage. They should not just offer desktop usage.""The solution needs to improve its flexibility. It's not as flexible as VMware.""The user interface needs to be improved.""It should have the functionality where if I move the mouse away from one screen, the context changes automatically."
