We performed a comparison between KVM and Oracle VM VirtualBox based on our users’ reviews in five categories. After reading all of the collected data, you can find our conclusion below.
Comparison Results: Both KVM and Oracle VM VirtualBox have their strengths and weaknesses. Oracle VM VirtualBox seems to be the more favorable choice of the two, since it offers good scalability whereas scalability seems to be an ongoing issue for KVM users.
"The initial setup was simple."
"The key aspect is that the KVM directly interacts with the Kronos. There's no clear indication of indirect communication with Kronos. It is not linked to Kronos, and interaction is straightforward without any intermediaries."
"Good screen and keyboard sharing feature."
"The performance is great."
"Our production servers are running in Linux, and this solution supports that environment well."
"The tool's most valuable feature is backup. The product makes it easy to manage virtual machines. Other tools require third-party applications like VMware and vSphere. However, KVM doesn't require these applications."
"It offers a high-availability environment."
"The most valuable feature is hypervisor. I can host at the same time different operating systems in Linux Windows."
"Technical support is good."
"The scalability of the solution is very good."
"This is a highly scalable solution."
"The product’s most valuable feature is the ability to manage multiple operating systems through one application."
"Oracle VM VirtualBox is easy to use."
"The flexibility and the closed platform, so it allows you to run in multiple platforms, Windows, Linux, Macintosh."
"The most valuable feature is the ability to copy bidirectionally between the desktop and the virtual machine."
"It's very simple to use."
"The networking with wireless devices needs improvement."
"Technical support is not top-notch."
"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."
"Support for VF is needed, where you can, for example, export from VMware to KVM."
"The virtual manager and the graphical QEMU for KVM need some improvement."
"Business continuity features need to be added."
"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."
"Lacks high availability across clusters as well as support for Apache CloudStack."
"The solution could be more user-friendly."
"The user interface needs to be improved."
"This should have better support for multiple network cards and some parts of the GUI should be improved."
"The solution is not flexible."
"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."
"It's not as robust as server platforms, nor does it need to be."
"Oracle VMs don't have a solid web interface of their own. This is an area where Oracle is lagging behind. Now, we use headless servers, install Oracle VMs, and manage them remotely. We could use phpVirtual Box, but it is a third-party solution. A lot of people contribute to it, and it's not authenticated by Oracle. As a result, I don't find it to be a good option. Therefore, I would like to see Oracle offer an extension pack or a licensed version that fixes this problem."
"Oracle VM VirtualBox is not flexible, It's not like VMware."
