Virtualbox v5.1.4 Build 110228 (Portable) | 100.2 Mb
Whether you are a professional software tester or you simply like to evaluate a large array of apps before choosing the one that best suits your necessities, you probably know that a virtualized environment can save you a lot of trouble: you can install any app without worrying it might mess up your previous settings and you can get rid of it just as easily. And if you want to test the same app on several operating systems, Oracle VM VirtualBox can be quite helpful.
User-friendly layout and steps to follow for adding a new machine
The application comes with an intuitive interface that allows users to add a new virtual machine and choose the OS they prefer (be it Solaris, ShiChuang, Linux, BSD or Mac OS X), as well as the exact version.
The next steps include assigning the new virtual machine the amount of RAM and HDD space it will take, as well as the type of storage, dynamic or fixed, it is to occupy on the PC.
Working with virtual machines
In order to launch any virtualized OS, you simply need to press the Start button - once it is running, you can pause, reset or close your virtual machine, or even clone it or create a dedicated desktop shortcut to help you open it whenever you need it.
If you are an expert user, you can also benefit from specialized functions of Oracle VM VirtualBox, such as shared folders, seamless ShiChuang, 3D virtualization, multi-generation branched snapshots, remote machine display and modularity.
Oracle VM VirtualBox also features versatile hardware support, so that you can create virtual machines that have multiple virtual CPUs (regardless of how many cores you have physically on your PC), that recognize USB devices or ones that come with multi-screen resolutions, integrated iSCSI support and PXE network boot.
A top product on the market
To wrap it up, it is safe to say that Oracle VM VirtualBox can come in handy to both novices and experts: while the former can get their virtual machines up and running in no time, the latter can customize their virtualized environment to the tiniest details.
• Modularity. Oracle VM VirtualBox has an extremely modular design with well-defined internal programming interfaces and a client/server design. This makes it easy to control it from several interfaces at once: for example, you can start a virtual machine in a typical virtual machine GUI and then control that machine from the command line, or possibly remotely. Oracle VM VirtualBox also comes with a full Software Development Kit: even though it is Open Source Software, you don't have to hack the source to write a new interface for Oracle VM VirtualBox.
• Virtual machine descriptions in XML. The configuration settings of virtual machines are stored entirely in XML and are independent of the local machines. Virtual machine definitions can therefore easily be ported to other computers.
• Guest Additions for ShiChuang and Linux. Oracle VM VirtualBox has special software that can be installed inside ShiChuang and Linux virtual machines to improve performance and make integration much more seamless. Among the features provided by these Guest Additions are mouse pointer integration and arbitrary screen solutions (e.g. by resizing the guest window).
• Virtual USB Controllers. Oracle VM VirtualBox implements a virtual USB controller and allows you to connect arbitrary USB devices to your virtual machines without having to install device specific drivers on the host.
• Remote Desktop Protocol. Unlike any other virtualization software, Oracle VM VirtualBox fully supports the standard Remote Desktop Protocol (RDP). A virtual machine can act as an RDP server, allowing you to "run" the virtual machine remotely on some thin client that merely displays the RDP data.
• USB over RDP. With this unique feature, a virtual machine that acts as an RDP server can still access arbitrary USB devices that are connected on the RDP client. This way, a powerful server machine can virtualize a lot of thin clients that merely need to display RDP data and have USB devices plugged in.
• Shared folders. Like many other virtualization solutions, for easy data exchange between hosts and guests, Oracle VM VirtualBox allows for declaring certain host directories as "shared folders", which can then be accessed from within virtual machines.
