Virtualbox
Installaton
Note that even the host machine is 64-bit, if the vT is not available/enabled in the BIOS, we cannot install 64-bit OS in the guest machine.

virtualbox failed to create the host-only network
Virtualbox (*.deb) was downloaded from virtualbox website. However, when I want to create a host-only network, I have to execute
sudo /etc/init.d/vboxdrv setup sudo apt-get install dkms build-essential linux-headers-$(uname -r)
This also solves the error "Kernel driver not installed (rc=-1908)".
Clone vs Import/Export appliance
Clone will create a new VM directory (including *.vdi) on the same machine.
Import/Export appliance (*.ova) allows to transport the appliance to a new machine. The appliance will not be touched on the new machine.

Emulation vs virtualization
Virtualization allows users to configure virtual machines outfitted with similar hardware and processors as the host system, whereas emulation simulates different hardware and processor configurations in software.
Emulators are what allow you to run old Commodore 64 or NES games on a PC, for example.
