# 3. Enhancing Virtual Machine Performance

In this section, we will introduce how to enhance virtual machine performance through the VirtualBox Extension Pack, including support for USB devices and enhancing network performance.

#### 3.1 Support for USB Devices

By installing the VirtualBox Extension Pack, we can enable virtual machines to support connecting USB devices, providing users with a more flexible usage method.

The specific steps are as follows:
1. Ensure that the VirtualBox Extension Pack is installed.
2. Enable the USB controller in the virtual machine settings.
3. Insert the USB device to be connected into the host and add USB device filter rules in the virtual machine settings.

Example code:

# Run the following command to install the VirtualBox extension pack
sudo apt install virtualbox-ext-pack

Code summary: By installing the extension pack and setting up the USB controller, USB devices can be connected in the virtual machine.

Result explanation: After successfully installing the extension pack, the virtual machine can recognize and use USB devices on the host.

#### 3.2 Enhancing Network Performance

The VirtualBox Extension Pack can also help improve virtual machine network performance, allowing for smoother network communication in the virtualization environment.

Here are some methods to enhance network performance:
- Set network connection to bridge mode.
- Adjust network adapter types to improve performance.
- Configure network bandwidth and transfer rates.
