| 8 | Welcome to Oracle VM VirtualBox.

|
|---|
| 11 | Oracle VM VirtualBox is a cross-platform virtualization application. What
|
|---|
| 12 | does that mean? For one thing, it installs on your existing Intel or
|
|---|
| 13 | AMD-based computers, whether they are running Windows, macOS, Linux,
|
|---|
| 14 | or Oracle Solaris operating systems (OSes). Secondly, it extends the
|
|---|
| 15 | capabilities of your existing computer so that it can run multiple
|
|---|
| 16 | OSes, inside multiple virtual machines, at the same time. As an
|
|---|
| 17 | example, you can run Windows and Linux on your Mac, run Windows
|
|---|
| 18 | Server on your Linux server, run Linux on your Windows PC, and so
|
|---|
| 19 | on, all alongside your existing applications. You can install and
|
|---|
| 20 | run as many virtual machines as you like. The only practical limits
|
|---|
| 21 | are disk space and memory.
|
|---|
| 22 | </p>
|
|---|
| 23 | <p>
|
|---|
| 24 | Oracle VM VirtualBox is deceptively simple yet also very powerful. It can
|
|---|
| 25 | run everywhere from small embedded systems or desktop class machines
|
|---|
| 26 | all the way up to datacenter deployments and even Cloud
|
|---|
| 27 | environments.

|
|---|
| 31 | Apple Mac computer, is running Windows Server 2016 in a virtual
|
|---|
| 32 | machine window.

| 46 | In this User Manual, we will begin simply with a quick introduction
|
|---|
| 47 | to virtualization and how to get your first virtual machine running
|
|---|
| 48 | with the easy-to-use Oracle VM VirtualBox graphical user interface.
|
|---|
| 49 | Subsequent chapters will go into much more detail covering more
|
|---|
| 50 | powerful tools and features, but fortunately, it is not necessary to
|
|---|
| 51 | read the entire User Manual before you can use Oracle VM VirtualBox.
|

| 54 | You can find a summary of Oracle VM VirtualBox's capabilities in

|
|---|
| 56 | users who just want to find out what is new in this release, see the
