Technical Specifications

System Requirements

VirtualBox requires a 64-bit operating system with at least 4 GB of RAM and 20 GB of free disk space. Additionally, the host system should have a multi-core processor and support for hardware virtualization (Intel VT-x or AMD-V).

Supported Operating Systems

VirtualBox supports a wide range of operating systems, including:

• Windows 10, 8.1, 8, 7, Vista, and XP
• macOS High Sierra, Sierra, El Capitan, and Yosemite
• Linux distributions, including Ubuntu, Debian, and Fedora

Secure Remote Access Guide

Enabling Remote Access

To enable remote access to your VirtualBox VMs, follow these steps:

1. Open the VirtualBox console and select the VM you want to enable remote access for.
2. Go to the VM’s settings and click on the ‘Display’ tab.
3. Check the box next to ‘Remote Display’ and select the protocol (RDP or VRDP).
4. Specify the port number and authentication method (password or certificate).

Connecting to a Remote VM

To connect to a remote VM, use a remote desktop client (such as Remote Desktop Connection on Windows or Screen Sharing on macOS) and enter the IP address and port number of the VM.

Backup and Snapshots

Creating Snapshots

Snapshots allow you to capture the state of a VM at a specific point in time. To create a snapshot, follow these steps:

1. Open the VirtualBox console and select the VM you want to snapshot.
2. Go to the VM’s settings and click on the ‘Snapshots’ tab.
3. Click on the ‘Take Snapshot’ button and specify a name and description for the snapshot.

Restoring Snapshots

To restore a snapshot, follow these steps:

1. Open the VirtualBox console and select the VM you want to restore.
2. Go to the VM’s settings and click on the ‘Snapshots’ tab.
3. Select the snapshot you want to restore and click on the ‘Restore Snapshot’ button.
