"A valuable feature of PowerVM is a feature that is used for higher availability plus stream for posting, which is very useful. There's a flash copy feature which we are using. PowerVM itself, I know, helps us to control and manage our Oracle licensing compliance, since it is our hardware partitioning. This is very important. If you use VMware, there will be a licensing issue. This PowerVM is a hardware partitioner, which is very important for license compliance. We are happy with this solution."
"It's scalable. Whenever we buy another product other than hardware, it's easily integrated into the virtualization software that we download."
"The case fileserver on the web server is the most valuable feature."
"The stability is the most valuable aspect of this solution. IBM is the most powerful and stable platform."
"Technical support is great."
"The most valuable feature is the flexibility in terms of managing the hardware resources such as RAM, CPU, and the network."
"The most valuable features in this solution are you do not get degradation in the performance like you could get in other solutions. There is a physical adapter that is better than a virtual one and you can assign adapters to a VM."
"Active Memory Sharing dynamically reallocates memory of running partitions based on changing workload demands. The memory for the pool is carved out from Physical memory and is made logical memory. The said memory is not available to be assigned to partitions as dedicated memory. A min, max and desired as well as weight is assigned to the memory of each lpar to help hypervisor make a decision in case a condition where priority is to be given to a certain lapr to use the memory form shared pool."
"Oracle VM VirtualBox is easy to use."
"The solution has high performance and is easy to use."
"The solution is very convenient and easy to use."
"It's a pretty good product in terms of monitoring."
"The installation is easy."
"This product is very user-friendly and easy to use."
"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."
"Technical support is good."
"If it could actually virtualize the entire platform it might be better. If you're having more than one virtualization technology, maybe there's a way to actually have less - one technology to run the data center and maybe one special virtualization for power. If it integrated with other platforms more effectively it might be better."
"I would like for IBM to be more focuses on the cloud."
"A GUI version of VIOS would be a great plus for people moving from Intel-based hypervisors."
"The interface is not user-friendly in places, so it could use some improvement."
"I don't know whether this has been trialed already, but IBM should give us an alert when we reach seven or eight failovers so that we can automatically switch it to manual mode. That would be great because if we cross the 10-day licensing limit, we have to pay a hefty license cost to Oracle. If IBM could view that feature, it would be helpful in license compliance."
"The performance should be improved."
"The licensing could be better."
"To make it a ten, I would like for them to add automation and configuration tools in order to help use the manager."
"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 AI and the UI could be improved. The user interface is a little outdated and the AI is not very attractive."
"The installation is difficult and could be improved."
"When I select the Ubuntu operating system from within the virtual machine, it sometimes hangs."
"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 solution needs to improve the methods used for starting and stopping the machine."
"The solution could be more user-friendly."
