"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."
"The snapshot feature is very powerful; it protects us from disaster."
"It's a pretty good product in terms of monitoring."
"The solution is very convenient and easy to use."
"The installation is easy."
"Technical support is good."
"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."
"VMware vSphere is user friendly. It is scalable and stable."
"The documentation is very good."
"Stability and scalability are the most valuable features of this solution."
"The solution is easy to use, user-friendly interface and has high availability features. When comparing it to other solutions it is more robust."
"I have found the solution to be flexible, and the vCenter and vMotion useful."
"The virtualization, the remote management user interface, and the web console are most valuable."
"It is very versatile. All features are beneficial and very good, especially DRS and resource pooling."
"I have found the Storage vMotion feature to be the most valuable."
"Oracle VM VirtualBox is not flexible, It's not like VMware."
"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 installation is difficult and could be improved."
"The solution needs to improve the methods used for starting and stopping the machine."
"It would be good if we could use Hyper-V Windows subsystems with Linux and VirtualBox on the same instance. Currently, to be able to use VirtualBox, we have to restart the machine into an instance of Windows where Hyper-V is disabled, which is understandably very inconvenient."
"The solution could be more user-friendly."
"I find the solution to be incredibly unstable, constantly falling over and not working properly."
"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 biggest room for improvement would be just simplicity. It is very intuitive, but it needs somebody with a lot of IT background."
"Pricing is starting to get a little high-end."
"The licensing costs for the solution are quite high."
"The solution should offer more integration capabilities."
"The reporting could be improved."
"Sometimes it's impossible to prevent problems from happening. With vSphere, you never know where the problem is going to come from, but you will always know that there is a problem. This is the problem."
"The only way for it to be a complete product is if you integrate all the functionalities. Then you don't need any backup solution anymore and you can do it by yourself. Integration needs improvement. They should improve a lot of the functionality because normally it's half of a product. You're only protecting yourself against technical failures but not against any cyber threats or any other stuff."
"We'd always like to see the price drop, but I realize that may not be realistic."
