No, there is no portable version released by Oracle, but there is a safe fork of the VirtualBox development. You can download and customize it the way you want it since it allows pre-customization before actual deployment. The tool is developed to support latest releases of VirtualBox application.

Note: There is a guide on the front page that explains how to proceed.
To use host-only networking, you need to make sure that the option is selected for installation. This can be done when you're installing the application.
You can see the in the image below where is located:
After this procedure, create a new virtual machine and access its Settings when you've finished creating it. Click the Network on the left, and select Host-Only Adapter. You can see in the image below as well.
Can VirtualBox create a bootable system? On a USB stick, for example.
No, you can't create a bootable system in VirtualBox. The application allows you to boot from a USB or a ISO, but it doesn't have the feature to create a bootable flash drive with the operating system. You will have to use another application to create a bootable USB with an operating system. For example, use Rufus or Unebootin to create a bootable USB and then assign it to the virtual machine created in Virtualbox.
This driver is installed and operated by VirtualBox. Most likely, you have not accepted the installation of the driver. Please perform a new installation of VirtualBox and when the installer prompts, please accept all the driver installation. Then it will work because that drivers were created to be compatible with operating systems where VirtualBox will be installed.
VirtualBox is a virtualization application which allows you to install multiple operating systems that can run inside your OS. The program does not make modifications to your system's integrity and functionality unless you choose the proper installation method (an actual partition drive instead of virtual hard disk). You can use the application however you want as long as you don't touch the partitions because things may get complicated if you do so.
Yes, there are extensions for VirtualBox, but they're not available for current version of VirtualBox. The Old Builds page provide a way to download these extensions. They're in .vbox-extpack file format. Double click the file you've downloaded from the OldBuilds page and VirtualBox will prompt you to install them. The extensions are used to increase VirtualBox functionality and they're created for:

VirtualBox features an automatic update features that can be triggered using the File menu. Open VirtualBox and go to File > Check for updates. A new window will appear with a progress bar. If there are any updates, VirtualBox will prompt you to download them, in case there aren't, it will display a message that the current product is already updated to latest version.
What are guest additions for VirtualBox?
Guest Additions are a set of drivers targeted for installation when an operating system has been fully installed and working. These drivers are used to optimize the guest system for better performance and usability. To install them, start the virtual machine, then access Tools from the Virtualbox menu bar and select Install Guest Additions. You will see that a virtual CD drive will be populated with these. An autorun menu will start. Simply click Next, Next, etc. until it's finished. Reboot the guest system and you'll have 3D graphics support, better mouse integration, USB support, keyboard/touch support, etc.
