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.
"It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox."
"The product's scalability is good...It's a very stable product."
"I have found KVM to be scalable."
"Our production servers are running in Linux, and this solution supports that environment well."
"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."
"The GUI interface makes the management of KVM easier than ever before."
"The most valuable feature of KVM is its stability."
"I appreciate the network passcode feature in KVM, as it provides a convenient way to manage DNS and cloud hosting."
"The flexibility and the closed platform, so it allows you to run in multiple platforms, Windows, Linux, Macintosh."
"VirtualBox provides an isolated, consistent environment"
"This solution creates a snapshot of virtual machines so you can create test environments."
"The pause feature is valuable. I can pause, which is something that not all hypervisors allow. The snapshot feature is also valuable."
"It's a pretty good product in terms of monitoring."
"This product is very user-friendly and easy to use."
"The solution has high performance and is easy to use."
"The product’s most valuable feature is the ability to manage multiple operating systems through one application."
"Business continuity features need to be added."
"Its resource usage can be improved."
"The product must provide better performance monitoring features."
"We would like to have a software lifecycle solution included in this solution. We can handle the software needed for KVM, but also the software that we provide. A lifecycle component would be very beneficial."
"The grid interface of KVM needs improvement. It could be more beautiful, especially when compared to VMware."
"The networking with wireless devices needs improvement."
"The stability of this solution is less than other products in the same category."
"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 solution needs to improve the methods used for starting and stopping the machine."
"It could improve slightly with enhanced reporting capabilities that show the current status of the network."
"The AI and the UI could be improved. The user interface is a little outdated and the AI is not very attractive."
"They could improve the graphics functionality of the product."
"Having live migrations to move a running server to other hardware would be great."
"The communications setup lags. It does not connect properly so the batching and networking is a bit slow."
"The solution is not flexible."
"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."
