Virtualization

Some examples of guest OS virtualization technologies include VMware Server and VirtualBox. Figure 4.8 provides an illustration of guest OS-based virtualization. Here, the guest OS operate in VMs within the virtualization application which, in turn, runs on top of the host OS in the same way as any other application. Clearly, the multiple layers of abstraction between the guest OS and the underlying host hardware are not conducive to high levels of VM performance. This technique does, however, have the advantage that no changes are necessary to either host or guest OS and no special CPU hardware virtualization support is required.

VirtualBox allows you to run guest operating systems using its own virtual computer system, which is why it is called a “virtual machine.” The guest system will run in its VM environment just as if it were installed on a real computer. It operates according to the VM settings you have specified (we will talk about settings a bit more later in this chapter). All software that you choose to run on the guest system will operate just as it would on a physical computer.

VirtualBox [15] is a powerful cross-platform virtualization application. Developed initially by Innotek GmbH and currently owned by Oracle. VirtualBox runs on existing Intel or AMD-based computer systems whether they are running Windows, Linux, Macintosh or Solaris hosts. It also supports a large number of guest operating systems including Windows (NT 4.0, 2000, XP, Server 2003, Vista, Windows 7, Windows 8, Windows 10), DOS/Windows 3.x, Linux (2.4, 2.6, 3.x and 4.x), Solaris and OpenSolaris, OS/2, and OpenBSD. VirtualBox is being actively developed with frequent releases and has a huge list of features, supported guest operating systems and platforms it runs on. Here are some of VirtualBox main features: Portability – VirtualBox runs on a large number of 32-bit and 64-bit host operating systems,No hardware virtualization required – VirtualBox does not require processor features built into newer hardware like Intel VT-x or AMD-v so it can be used even on older hardware,Guest additions – software packages which can be installed inside of supported guest systems to improve their performance and to provide additional integration and communication with the host system,Great hardware support – guest multiprocessing, USB device support, full ACPI support, multiscreen resolutions, built-in iSCSI support and PXE network boot,Virtual machine groups – a feature that enables users to organize and control virtual machines collectively, as well as individually,Remote machine display – VirtualBox Remote Desktop Extension allows a high-performance remote access to any running virtual machine.
