Ada beberapa cara untuk memperoleh OpenWRT x86 porting untuk VirtualBox.
- Download vdi image (ex. attitude_adjustment/12.09/x86/)
- Download + convert raw image (ex. attitude_adjustment/12.09/x86/)
- Compile image anda sendiri, pastikan

Convert OpenWrt raw image
Langkah ini dibutuhkan untuk release & snapshot lama. Release 10.03.1 ke atas sudah memberikan image VirtualBox.
Uncompress image jika di perlukan:
gunzip openwrt.img.gz
Convert openwrt.img menjadi native VirtualBox format:
VBoxManage convertfromraw --format VDI openwrt.img openwrt.vdi
OpenWrt and Kernel version
Choose a Name for your virtual machine Choose Linux for your Operating System Choose Linux 2.6 for your Version Click Next Optionally decrease RAM size from 256 MB to something smaller Click Next
Choose Use existing hard disk Click the file icon to open Virtual Media Manager
Click Add and your .vdi or .vmdk file using the dialog Select your drive from the list and click Select Click Next and Finish

Troubleshooting
If your virtual machine won't boot, make sure your hard disk is connected using IDE (not SATA)
Right click your machine's entry on the machine list and choose Settings then select Storage
If you see that your hard disk image is connected to a SATA controller; under Storage Tree select the SATA Controller entry and then click Remove Controller
Click Add Controller and then select IDE Controller
Select the IDE Controller you just added and then click Add Attachment and choose Add Hard Disk
Add your OpenWRT image as before
If your virtual machine still won't boot, make sure you have a Serial Port enabled.
Enable a serial port under Settings then Serial Ports
If your virtual machine boots but doesn't activate the console
Press Enter
If you rebuild the disk image, and VirtualBox complains about invalid UUIDs for the disk
You need to remove the disk from the VM, and _also_ from the Virtual Media Manager, the add the disk image to the VM again
Set up networking with clients
In the VirtualBox Settings for Network configure:
Adapter 1 to internal network with name OpenWrt-lan
Adapter 2 to Bridged adapter or NAT
Boot up OpenWrt and add to /etc/config/network

option 'proto' 'dhcp'
option 'ifname' 'eth1'
Start the wan with ifup wan Create a new Virtual machine with your client operating system of choice On the client set Adapter 1 to internal network with name OpenWrt-lan Boot client
