"It's a pretty good product in terms of monitoring."
"The installation is easy."
"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."
"The solution is very convenient and easy to use."
"Oracle VM VirtualBox is easy to use."
"The snapshot feature is very powerful; it protects us from disaster."
"The solution has high performance and is easy to use."
"Proxmox VE is simple to use and it is feature rich. The fact is that it performs,"
"It is easy to deploy."
"The backup service, which was released recently, and that we are already using, is wonderful."
"The feature that I have found most valuable is that its storage container, LVM, and everything else work out of the box."
"We are happy with Proxmox VE. We use it as part of a cluster."
"The affordability of the solution is the product's most valuable aspect."
"The solution is extremely scalable."
"It fits in well with our organization. It works and does what it says it does."
"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."
"Oracle VM VirtualBox is not flexible, It's not like VMware."
"When I select the Ubuntu operating system from within the virtual machine, it sometimes hangs."
"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."
"I find the solution to be incredibly unstable, constantly falling over and not working properly."
"The solution could be more user-friendly."
"We are using servers individually, and we are looking for a reliable application that allows us to hop between servers with high availability."
"Its performance and support can be improved. Currently, there is a cost for support."
"A feature which should be added is the ability to encrypt the main installation."
"It is a good solution, but it is very complicated in some ways. It is not easy. You must have experience in the console mode to do some configurations. A lot of documentation and YouTube videos are available that you can use to learn about it."
"One issue with Proxmox is that some processes are not automatic. For some processes, you have to do it manually by command line."
"It's one of those things for me to move things on to the cloud. It's not so easy. I am always on the laptop and have to monitor that because if you want to make strides; you need to stay online."
"I can't speak to any improvements. It is not lacking features."
"The availability of the solution could be a bit better."

Proxmox VE is a very fast and powerful solution. It offers feature-rich virtualization, has open-standards compliance, and also includes redundancy and failover capabilities. What I like about Proxmox VE is that it lets you rack and stack two or more nodes and enables you to be up and running with a one-node failure tolerance in very little time. Proxmox VE’s integration with ZFS is also fantastic. It allows you to create pools to store your VM images and data on very easily and their great web UI makes it easy to check drive health, ZFS scrub status, and other things. I think the best part of the web UI is that everything is configurable from the web user interface without having to use the command line. It also has graphs and additional visualizations so you can evaluate the performance of everything. Beyond that, even though you can use Proxmox VE on a single server, the solution makes it easy to set up a high availability cluster on multiple hosts if needed.
Regarding Oracle VM VirtualBox, I would say its most valuable features are its virtualization, its compatibility with older OSes, and its testing of environments without causing interruptions or any harm to production. Besides making it possible to run multiple VMs on a laptop or desktop, its ease of deployment makes the solution appealing. Not only is it easy to set up, but the software is free. Moreover, it has a nice interface. However, I think Oracle VM VirtualBox could use some improvements on its reporting as well as on its network settings for VMs, which can sometimes be hard for the average user to find and understand.
Conclusion: While Oracle is a safe and excellent option when it comes to virtualizing an operating system, I would suggest Proxmox VE because it is newer, has a lot of powerful features, and is a very reliable and stable solution.
