"I like that it's easy to manage. It's also more powerful when it comes to security than others. That point of view is the one consideration. The other consideration is that it's cost-effective."
"This solution is open source and easy to configure."
"The GUI interface makes the management of KVM easier than ever before."
"If you prefer command-line, there are all kinds of command-line options."
"KVM is stable."
"Good screen and keyboard sharing feature."
"It is easy to use, stable, and flexible. It is a pretty mature product, and it is faster than VirtualBox."
"Very cost-effective."
"The good thing is that it is multi-platform. Once you create a virtual machine in one particular environment, you can switch over to see if you can run it in other environments. For example, if you are on Windows and you create this virtual machine, you can actually go ahead and change the operating system. You can switch it over to Linux or Mac OS and see if you can run the VirtualBox on those particular machines. It even runs on some of the commercial operating systems that are not mainstream, such as Solaris and BSD. These kinds of operating systems are also supported by VirtualBox. The other thing that is good about VirtualBox is that it is open source. So, if you need to do any modifications for your own purposes, you can just download the source, modify it, and deploy it in your environment. It is pretty good and very versatile. You can create and manipulate virtual machines from the command line, which is also very important. It's something that some other products on the desktop side do not have. VMware Fusion and Parallels Desktop don't have a good command-line interface to create and manipulate virtual machines, whereas VirtualBox has it out of the box, which is pretty good."
"This product is very user-friendly and easy to use."
"It's a pretty good product in terms of monitoring."
"Technical support is good."
"The snapshot feature is very powerful; it protects us from disaster."
"Oracle VM VirtualBox is easy to use."
"The solution has high performance and is 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."
"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."
"Business continuity features need to be added."
"There are some issues with the graphics and some software that is very complex."
"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."
"Its resource usage can 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."
"Monitoring and resolution could be improved."
"Lacks high availability across clusters as well as support for Apache CloudStack."
"The installation is difficult and could be improved."
"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."
"The solution could be more user-friendly."
"It has some issues when you have some weird device drivers. For instance, when you have a weird sound driver working on your machine, and the VirtualBox needs to output the sound of the virtual machine into the sound driver of the physical machine, the bare metal, it doesn't work too well. If you tweak lots of drivers and play around with the different kinds of drivers and machines, you will probably break something. I have not played with it too much and maybe it already supports it, but it would probably be good to have the ability to use a container from the virtual machine environment instead of spinning off a complete virtual machine. There are other tools for that. On Linux, you have a DXE, LXC framework, and you have Docker as well. Docker is good because it is multi-platform, and you can run Docker on pretty much anything, even different processors, but it would be good if we had a VirtualBox running on it while spinning off containers instead of full virtual machines. The other thing that will become important, and I'm pretty sure that they are thinking about it as well is that there's this new hardware platform that Apple is releasing, which is an ARM-based new chip. So, VirtualBox will probably have to work on ARM-based CPUs as well."
"The AI and the UI could be improved. The user interface is a little outdated and the AI is not very attractive."
"Oracle VM VirtualBox is not flexible, It's not like VMware."
"I find the solution to be incredibly unstable, constantly falling over and not working properly."
"The solution needs to improve the methods used for starting and stopping the machine."
