  • Conflicting network settings between the host machine and the guest operating system
  • Outdated or incompatible VBox drivers

  2. Step 2: Click on 'Settings' and then navigate to 'Network' tab
  3. Step 3: Configure the network settings according to your host machine's network configuration (e.g. static IP, DNS, etc.)

  1. Step 1: Open the VirtualBox Manager and select the affected virtual machine
