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.

To make changes, you need to use the command lines. You need to use them to change the volume or extend or re-sync the volume. We've tried to do so using the web manager and it's not working well. Basically, the GUI and command-line interface need improvement. We'd like the command line to manage the VDI disk.

The product should improve its scalability. It should be more flexible to be used with desktops with different capacities. We do not have much storage on our desktops, and we must allocate a certain amount of memory to install the product. When we install a virtual machine, we have a limit that we cannot exceed 80% of RAM.

Oracle VMs don't have a solid web interface of their own. This is an area where Oracle is lagging behind. Now, we use headless servers, install Oracle VMs, and manage them remotely. We could use phpVirtual Box, but it is a third-party solution. A lot of people contribute to it, and it's not authenticated by Oracle. As a result, I don't find it to be a good option. Therefore, I would like to see Oracle offer an extension pack or a licensed version that fixes this problem.

Oracle VM VirtualBox doesn't work properly with an antivirus tool. I think Oracle has to come up with something that makes VM VirtualBox compatible with different antivirus applications. Though you can get Oracle VM VirtualBox running properly even without an antivirus tool, it keeps you vulnerable.

We are using the free version of Virtualbox, so we have not tested the commercial solution.

That said, having live migrations to move a running server to other hardware would be great.

The ability to emulate other types of CPU and hardware, such as PowerPC in both Little Endian and Big Endian, ARM CPU, s390x CPU architectures, and possibly older CPUs such as Motorola would be helpful. This would make the development of new software releases faster and easier.

In general, it is a good and stable product to use. We love it!

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.

We are currently on version 5.1.38 but we are definitely going to upgrade to version 6. Some of what I would like to see in the future may already be in that release.

For me, it would be great to have a function where I can teleport from one machine to another machine just using the GUI. At the moment, this capability is only available via the command line. Other products like VMware and Windows Hypervisor already have that functionality. I think it would be an excellent addition and improve the product if Oracle implemented this functionality directly in the GUI. 

The feature I would like in addition to teleporting is that I would like to see more reporting capabilities. For example, it would be good to be able to easily report on the status of the servers and virtual machines. It would be enough just to get a list that says how much CPU power each machine is using, the amount of memory it occupies, etcetera. Something like a snapshot of everything in graphical format. A dashboard that actually combines all the reporting about what is happening on your virtualization would be valuable. Getting all the information at a glance is what I would like to see.

The product needs better support for multiple network cards. That is the major area that sometimes it can be a bit of a mess to configure multiple network cards to communicate well with each other. That's the major thing for me.

Another thing I've run into is that it would be nice on Oracle if you can use something like a Hyper-V environment. You can just install the environment and then start installing all your virtual machines on top of that. Rather than having to install Windows or Linux when you need them, you just install the VirtualBox. If it can just roll out on its own and had its own hyper vista software — that would be something I've been praying to see from Oracle VirtualBox.

I think also that a challenge I've seen some people have after I convince them to use the product is when they are switching to various views. In some situations, the view switches to a seamless full screen and the menu bar disappears. When this happens they may not know how to switch it back. I don't know if Oracle can put a button on-screen so that when you are in a seamless view or scale view or something like that so those familiar things still fit where you can find them. In fullscreen, you still have the menu, but in some of these screen views that don't have the menu, they could put a visible button that can bring the menu back up. With that, you can easily get back familiar controls and eject your USB or whatever you need to do. If you don't know the shortcuts, it can be difficult to navigate or do even common tasks. They need something else instead of just using keyboard shortcuts.

I have to keep pressing the home key so that the mouse changes context, which is something that I don't like. It should have the functionality where if I move the mouse away from one screen, the context changes automatically.

This solution cannot run when Hyper-V is running, and it would be nice if these two solutions could co-exist.

I have never used this solution for production, but I wish there was a simpler way of deployment, and I wish there was an ecosystem around it. Some other solutions, such as Docker, have a whole surrounding ecosystem. You know where to get Docker files, you know what Docker works with, etc. It's a whole ecosystem instead of a single application. It comes with almost everything you need in one place, or in the community.

If I could maybe have cloud images, that would be awesome. It's going to be hard to manage cloud with a cloud, or image with an image, but hey, if it can be done, we can do that, too. Why not? You have mobility, so you can use something. You can have a server with all of the VirtualBoxes there and the images there. For example, if you are managing an application, you can use it from a touch of a screen. Why not?

While in the past I used the solution on Linux, which I no longer do, and FreeBSD, which is my daytime runner, I am not very happy with its use on the latter. For the past year or so, it slowed down upon its use. 

I am not a great fan of Oracle's products. I have not been happy with these since version 6. I find the solution to be incredibly unstable, constantly falling over and not working properly.

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.

One of the things that we need, because with LeVAULT we control the authentication layer, and we support multiple factors for authentication -  anywhere from four to 27 factors  - and we allow you to be able to raise your key's devices, as keys to authenticate, as one of the factors. We're working with them to be able to allow the local USB ports to be ported over to the remote desktop, running VirtualBox.

We didn't talk about the capability of improving playing video, and being able to download; and streaming.

It needs better support for 3D. This would allow us to virtualize operating systems used by designers or architects. The base virtual disk (VDI file), which contains the state before taking the snapshot, should be aware if it has some related snapshots. This would help to eliminate issues when moving or migrating virtual machines to new hardware, e.g. if you move the base virtual disk file but forget to move the snapshots.

Networking options need improvement. Once I had an idea to move my development work into Ubuntu, however it is not possible to run VM within VM. The solution is to play around with the networking so that all VMs run within the same network and use one of them as a master node. But sometimes I need to test the scripts to run in a different network. I couldn't find an easy solution for that situation.

VirtualBox is more of a desktop deployment, so we don't really use it in production workloads. For improvement, compatibility with other virtual machine systems would be helpful. The ability to deploy the imagine of other virtual machines and convert it to a virtual desktop environment needs to be better.

The solution should have more enterprise features, like migration, high availability storage, disaster recovery, and the ability to deploy to enterprise-scale usage. They should not just offer desktop usage.

Even with the "add-ons" tools that come with OracleVM, some features that are available in other solutions, are simply not there.One mentioned in another review, is the dragging and dropping of files between host and VM. Another major issue, is that you technically cannot use this software to host a remotely accessible virtual machine without using alternative access software such as VNC or RDP, depending on your virtualized OS.Back when I started using OracleVM, Sun Microsystems was a separate company and it was called Virtualbox. I stopped using it for one reason and one reason only, because Oracle closed off portions of the code, creating an OSE (open source edition) and a CSE (closed source edition) of the software.

Also, it continues to upgrade itself, and I would like an option to switch this off because it causes slowdowns for the network.
