Oracle VirtualBox is an open source, cross-platform, virtualization software, enables developers to deliver code faster by running multiple operating systems on a single device.
IBM PowerVM is the best and most stable product in the virtualization market. It gives the best performance with IBM Power Server, especially its best solution, where we have to run critical applications and save applications licensing costs. It provides a lot of good features …
Very similar, just supporting different operating system environments. Both products are rock solid and well supported. Both products have a surrounding group of other management products that are tested and integrated to provide a comfortable group of system support …
Our company utilizes VMware and PowerVM. VMware is very user friendly from an IT support view and makes supporting Windows OS easier. PowerVM is moving in that direction. PowerVM is better in that you can prioritize workloads across different VMs and be granular in your …
Oracle VirtualBox is the better choice due to its cost-effectiveness, ease of use and feature set. However VMware Workstation is more suitable due to its superior performance, better features and better integration with enterprise tools. VMware Workstation also provides a …
It always depends on the usecase which product is better suited. But generally, Oracle VM VirtualBox is very easy to set up on every operating system and is intuitive in the usage. Compared to VMware Workstation it offers less features but for a basic setup, I prefer Oracle VM …
Oracle's solution is entirely free, although a bit clumsy and visually outdated. Hyper-V can and will be a better match due to having more resources, offering full Microsoft Support, and being focused mainly on corporative uses, but for a small environment, it can be like …
VirutalBox is very similar to using Vmware with the slight difference in appearance and what might be considered a less polished look. However, what it lacks in polish and looks it makes up for in functionality, easy of use and the wide range of operating systems and features …
While Parallels Desktop has always positioned itself better than VirtualBox, it will never be able to compete against free and open-source software. Yes, it is true that it has some extra seasonings that can make the scale move towards Parallels at the time of the election, …
VMWare Workstation required VMWare Workstation Pro to create the system before we could use it. The license requirements for the latter was the issue as we needed this for dev/test environments as well as to show POC on virtualization without necessarily incurring a cost at the …
Docker, and automated machine provisioning in DevOps often uses the metaphor "treat your machines like cattle, not pets." VirtualBox's intended use is definitely in the creation, management and use of "pet" machines, whereas many similar products are more in the "cattle" …
The main benefits of Oracle VM VirtualBox are its licensing terms (it is free), its open-source nature, and its active community. However, its various competitors do a much better job when it comes to both ease of use and, most importantly, speed. For example, Parallels Desktop …
We've used VMware, and continue to use it for some projects. But, in my experience, the latest updates to VMware run very slowly, particularly on macOS. Many blog posts offer tweaks to help speed up VMware, but none of these tweaks make a significant difference.

Chose Oracle VirtualBox
We primarily use Oracle VM VirtualBox because it's free, and it is the default provider for Vagrant, which we use for our development VMs. The user interface of VirtualBox looks a little clunky in macOS, but I actually almost never see the main VirtualBox interface because I …
With regards to how some of the other virtualization software packages stack up again VirtualBox, I would say VirtualBox is ahead of the game especially when it comes to cost savings, as there is no ongoing cost for running the software. A big disadvantage to one of the other …
As I mentioned earlier, Oracle VM VirtualBox and VMWare Workstation offer roughly the same type of features. One of the main differences is that VMWare Workstation is a commercial product while Oracle VM VirtualBox is open-source. Resource utilization and graphics support is …
VirtualBox is just as robust and as functional as the VMware desktop product. It actually has more features and in some ways is easier to work with. I've also found that VirtualBox supports newer operating systems better than VMware Workstation. There's also the cost advantage …
I have used Parallels as well as VMware Workstation and have always returned to VirtualBox. VirtualBox is free which makes it easy to try. Compared to the others, it does everything I need. In +7 years I have not been able to justify the cost of a Parallels Desktop or VMware …
We feel like we made a good decision going with Oracle VM VirtualBox because it was more enterprise ready. They had great customer success team and proper API compatibility which allowed for great integration into our legacy tools. The support we got from the development …
It's free, fast, and really well built. Obviously, VMware is the key competitor, but I consider that more of an enterprise app for building and managing entire networks of virtual systems, whereas VirtualBox is fantastic as a personal VM tool. What it lacks in enterprise-grade …
It's much more useful than VMware workstation player because you can't edit anything at all with that free version of vmWare. This is just about as capable as VMware fusion and Workstation until you pay even more to use vSphere, and then you start having enterprise features.
In a Windows environment, Docker would not even be possible, to begin with. Also, on the way around, having a Linux based Machine, without Oracle VM VirtualBox, one would have to create a partitioned disk and enable it at boot time in order to be able to run Windows in such a …
IBM PowerVM only is available on IBM POWER machines. It makes live much easier, compared to bare metal machines (OPAL) or machines with KVM. Personally I would not like to manage systems that don't have IBM PowerVM. The current line-up always includes IBM PowerVM (firmware built-in).
It is best suited when you want to have different operating systems on your laptop or desktop. You can easily switch between operating systems without the need to uninstall one. In another scenario, if you expect some application to damage your device, it would be best to run the application on the VM such that the damage can only be done to the virtual machine. It is less appropriate when time synchronization is very important. At times the VMs run their own times differently from the host time and this may cause some losses if what you doing is critical. Another important thing to take note of is the licensing of the application you want to run your VM. Some licenses do not allow the applications to be run on virtual servers so it is not appropriate to use the VM at this time.
Can spin up multiple VMs on a host-only network that speak to each other and allow for interesting test environments spun up at will.
Cross-platform functionality allows me to run it on my Linux Desktop and know that tutorials I make with it could be approached by someone on a Windows or Mac OSX system. Hyper-V is limited to Windows, and VMware Workstation requires a license (VMware Player is free, but is not open-source and is more limited in comparison to VirtualBox).
If you are testing tools like Vagrant and Test-Kitchen, VirtualBox often seems to have the highest amount of support and documentation when it comes to compatibility (though, many people do use Hyper-V or VMware Workstation without issues).
Each LPAR comes with a profile that sets a minimum, desired and maximum capacity (like for CPU). You can freely change the allocated CPU between the minimum and maximum on-the-fly. If you want to change the resource below the set minimum or above the set maximum, you need to shutdown the partition first and change the profile. It would be nice if there was a way to do that without downtime too.
(Setting the maximum very high is fine for CPU but not for memory as it allocates a fixed percentage of the maximum (not the current) size for internal housekeeping).
When you manage your Power system with an HMC, a lot of firmware updates can be done concurrent (on-the-fly), not requiring a power-cycle of the machine. If you use Novalink to manage your systems, this proces becomes broken and you need downtime on your physical system. You can use Live Partition Mobility to move every partition off of this system first, but still...
The memory footprint is high, and requires above 8 GB of memory to run an Ubuntu VM smoothly (considering developing inside ubuntu OS inside a MacBook Pro).
Some known issues with OVF/OVA images import/export. We had the issue of some sections in OVF being ignored (especially Startup and Install sections).
Some intermittent issues when mounting external hard drives and trying to access them from within the running VM.
The product works. It provides the proven environment to support IBM's primary operating systems that run on the IBM Power processing systems. This by extension includes the IBM various storage products that work within that environment. It has proven to be seamless as the environment has grown and as various new products and version updates have been added. As with most IBM products, the support is excellent.
Since it is built into the firmware (hardware) it requires no separate installation (except for the Virtual I/O servers, if you need those). Both HMC and Novalink (with PowerVC) support IBM PowerVM well and offer a user-friendly interface to setting up LPARs and making changes, most on the fly. Modern systems also give insights into performance, power consumption etc. A lot of separate tools exist to show more details, like LPAR2RRD, IBM Instana, IBM Turbonomic etc.
I love using the Graphical User Interface. The VirtualBox Manager is very easy to understand and use. You can quickly create, configure and manage all your virtual machines in one window. It makes operating virtual machines easy and simple. When using VBoxManage it gives the user comprehensive control over VirtualBox so that you can use automation and scripting at the command-line interface
IBM PowerVM is the best and most stable product in the virtualization market. It gives the best performance with IBM Power Server, especially its best solution, where we have to run critical applications and save applications licensing costs. It provides a lot of good features like LPM, shared processor pool...etc, which makes the environment more flexible.
VirutalBox is very similar to using Vmware with the slight difference in appearance and what might be considered a less polished look. However, what it lacks in polish and looks it makes up for in functionality, easy of use and the wide range of operating systems and features it supports without the need of buying the full professional edition
The only problem I have found is that the deployment is dependent and intrinsically linked to the Host OS. This is different from bare metal solutions which remove that dependency on a Host OS. The latter is more reliable and removes a layer of potential failure.
It has provided the performance we need during month end and year end closing cycles.
It has been very reliable with little to no downtime.
We have been able to stretch our IT dollars because the refresh rate on IBM Power can run for years. Also, we have been able to add many more VMs to physical machines than other platforms can run.
