Evaluating Oracle Linux From Inside Oracle VM VirtualBox [31004]
VirtualBox allows you to have multiple virtual machines running simultaneously on a single physical machine
Yuli Vasiliev writes, "For years, the only way to evaluate a new operating system was to install it on a dedicated machine, as a standalone system, or with existing operating systems in a multiboot scenario. In any case, you had to install your operating system on the bare metal and, therefore, you did not have the ability to run more than one operating system at a time on a single physical machine.
This situation has changed since cross-platform virtualizers such as Oracle VM VirtualBox appeared. With such a virtualizer installed in your system, you obtain the ability to have multiple operating systems running simultaneouslyeach in a separate virtual machine (VM)on an individual physical server.
This article discusses how you might evaluate Oracle Linux, running it inside a virtual machine on top of your existing operating system..."

Oracle VM VirtualBox: Personal Desktop Virtualization [30634]
Detlef Drewanz Discusses Installation and Employment
In part 6 of an eight-part series Detlef Drewanz writes about "Oracle VM VirtualBox - Personal Desktop Virtualization" describing Oracle VM VirtualBox and its uses. Oracle VM VirtualBox requires an already-running host operating system on top of which it can be installed. Following installation one can simultaneously run multiple guest operating systems inside Oracle VM VirtualBox using multiple virtual machines (VMs). Oracle VM VirtualBox consists of three parts: the base software package; guest additions; and extension packs. Drewanz next addresses how data can be transferred to and from the guests through external iSCSI storage, with shared folders from the host or via network services.
