Technical Specifications
Virtualization Modes
VirtualBox supports two virtualization modes:
- Software virtualization: This mode uses software to emulate the hardware, allowing you to run guest operating systems on a host machine without the need for hardware virtualization support.
- Hardware virtualization: This mode uses hardware virtualization support (such as Intel VT-x or AMD-V) to improve performance and security.
Networking Options
VirtualBox provides several networking options, including:
- NAT (Network Address Translation): allows guest operating systems to access the internet using the host machine’s IP address.
- Host-only networking: allows guest operating systems to communicate with each other and the host machine, but not with the internet.
- Bridged networking: allows guest operating systems to access the internet and communicate with other machines on the network.
