How to run OpenWrt in VirtualBox

The official doc seems too complicated OpenWrt on VirtualBox HowTo

  1. Download and install VirtualBox. On Windows add to PATH envs C:\Program Files\Oracle\VirtualBox
  2. Get an OpenWrt image openwrt-x86-64-combined-ext4.img.gz from targets/x86/64/ folder. Direct snapshot download
  3. Uncompress the image: gunzip openwrt.img.gz
  4. Convert it to native VirtualBox format:
VBoxManage convertfromraw --format VDI openwrt.img openwrt.vdi
