Key Concepts
·
Host operating system
·
Guest Operating System
·
Guest Additions
·
Virtual Machine (VM)
the special environment that
VirtualBox creates for a guest OS while it is running.
Virtual Networking
VirtualBox provides up to 8 virtual PCI Ethernet cards.
for each virtual machine.
Networking Modes
·
Network Address Translation (NAT)
It is the default value, it is
used when no services are hosted. Services will be reachable with
127.0.0.1:port
·
Bridged Networking
It provides direct external
access to the VMs. VMs will user the host physical network adapter directly.
·
Internal Networking
It is used to create a network
containing the host and a set of virtual machines, without the need for the
host's physical network interface. Every internal network is identified simply
by its name, once there is more than one active virtual network card with the
same internal network ID, the VirtuaBox support driver will automatically
"wire" the cards and act as a network switch.
·
Host-only Networking
A virtual network interface is
created on the host, it provides the connectivity among virtual machines and
the host. A service hosted in a VM could use a Host-only Networking to talk to
a database hosted in another VM, then use a bridged networking to expose
services.
Remote Display (VRDP) Support
VirtualBox Remote Display Protocol (VRDP) is a
backwards-compatible extension to Microsoft's Remote Desktop Protocol (RDP).
VBoxManage
Command-line interface to VirtualBox.
Importing and exporting Virtual Machines
VMs could be imported and exported using the Open
Virtualization Format (OVF).
