IBM PowerVM vs. Oracle VirtualBox

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.

• IBM PowerVM is reliable and fully redundant with no single points of failure
• Once it is set up, there is not a lot of maintenance that needs to be done on it
• It gives you a lot flexibility by using features like LPM

• 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.

I give this rating because virtual box is inexpensive but there is another product such as vm ware that can also be used

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

Dependency on the Host OS means it is as reliable as it is possible to be. Application errors are beyond the purview of the application.

No issues, especially with the extensions addons.

Oracle have a very fast response rate and a strong user community. One can geet help from many sources if they choose to research for themselves.

We really enjoy using virtual box. We do not require to buy expensive hardware but instead we can minimize costs and maximize profits.

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.

• Direct cost savings - it enables me to do the work I need to do without purchasing additional physical computers
• Time savings - it allows me to perform testing and reversion that would take much longer on a physical computer
• Increased productivity - it enables me to more easily integrate with customer environments
