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 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."
"I appreciate the network passcode feature in KVM, as it provides a convenient way to manage DNS and cloud hosting."
"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."
"The KVM service is well managed with a central policy interface."
"The GUI interface makes the management of KVM easier than ever before."
"Our production servers are running in Linux, and this solution supports that environment well."
"The most valuable feature is hypervisor. I can host at the same time different operating systems in Linux Windows."
"The product's scalability is good...It's a very stable product."
"This product is very user-friendly and easy to use."
"The pause feature is valuable. I can pause, which is something that not all hypervisors allow. The snapshot feature is also valuable."
"The flexibility and the closed platform, so it allows you to run in multiple platforms, Windows, Linux, Macintosh."
"The scalability of the solution is very good."
"Technical support is good."
"The solution's most valuable feature is its stability."
"I like that it has a snapshot feature."
"It's very simple to use."
"In KVM, snapshots and cloning are areas where there could be a little more sophistication, like VMware."
"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."
"The speed is around thirty percent slower than another competitor. This would be something to work on."
"Technical support is not top-notch."
"Lacks high availability across clusters as well as support for Apache CloudStack."
"Monitoring and resolution could be improved."
"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."
"I have encountered difficulties in getting the tool's documentation."
"I think that this solution should be more user-friendly."
"The installation is difficult and could be improved."
"The solution lacks some open source remote administration tools. The reload of individual virtual machine definitions through the vboxweb service (via its API) without restarting it and the access to shared storage (to use teleport functions) need to be improved."
"The user interface needs to be improved."
"I find the solution to be incredibly unstable, constantly falling over and not working properly."
"The solution is not flexible."
"Oracle VM VirtualBox doesn't work properly with an antivirus tool."
"It should have the functionality where if I move the mouse away from one screen, the context changes automatically."
