This document describes how to run the x86-64 OpenWrt images in VirtualBox, or VB for short.
 
−
Prerequisites
 
−
 
 
−
* Download and install VirtualBox
 
−
* Download and install the Virtualbox Guest Additions (needed for USB connectivity among others)* Download the openwrt-x86-64-combined-squashfs.img image, from snapshots/targets/x86/64/(On Linux, downlaod the openwrt-x86-64-combined-ext4.img image)
 
−
* Open a terminal and go in the folder where you have downloaded the file (sorry, the tool has only a command line interface)
 
−
* Convert it to native VB format by writing this in command line (the same for Windows, Mac and Linux. Sadly this tool does not have graphical user interface):

−
Start VirtualBox and click New to add a virtual machine (VM)
 
−
 
 
−
Choose a Name for your virtual machine, choose Linux for Type, and Linux 2.6 / 3.x / 4.x (64-bit) for Version, then click Next.

OpenWrt will work fine with much less RAM than the recommended amount, 128 MiB will be enough.

Choose Use an existing hard disk file, click the file icon to open Virtual Media Manager, click Add and choose your .vdi file using the file chooser window. Click Create to end this guided procedure.

−
:!: It's recommended to place the disk image in a permanent place before linking it with VB. If you move it afterwards, VB will not find it anymore and will complain about this issue on next start (or when you try to start the VM). It will offer a guided procedure to link the disk image again, so don't worry.
 
−
VM setup
 
−
 
 
−
This part of the configuration will deal with setting up networking manually.
 
−
The configuration you will set up by following this tutorial is:
 
−
 
 
−
* eth0 of the VM on mng (management) interface, fixed address 192.168.56.2, set in Virtualbox as Host-only Adapter on adapter vboxnet0. This interface will be always available to the host even if host or VM are disconnected from any network.
 
−
* eth1 of the VM on wan interface, dynamic address, set in Virtualbox as NAT. This interface will be used to access the Internet through whatever setup the host also uses.
 
−
* (optional) eth2 of the VM on lan interface, configured depending on your local network, set in Virtualbox as Bridged Adapter. This interface allows other devices (host included) to connect to the VM as if it was a physical device in the local network. Will only work if there is already a local network of some kind.
 
−
* For a setup with 2 bridged physical network cards WAN/LAN Setup see troubleshooting. The rest of this guide applies to a setup with 2 physical cards as well.

−
Virtualbox settings
 
−
Host-only network adapter
 
−
 
 
−
we first need to make sure there is a Host-only network adapter and that it has the right settings
 
−
 
 
−
* click on File → Preferences → Network
 
−
On macOS, this setting may be found through File > Host Network Manager…
 
−
* click on Host-only Networks tab and then if you don't see a vboxnet0 entry click on the + icon on the right of the window to add a new one.
 
−
Now select the vboxnet0 entry, and click on the screwdriver icon on the right to open its settings.
 
−
* IPv4 Address should be 192.168.56.1, IPv4 Network Mask should be 255.255.255.0, IPv6 Address should be empty and IPv6 Network Mask should be 0
 
−
 
 
−
(optional) you can also set the DHCP server as shown in the screenshot if you want to have dynamic addresses to the VM, but for this tutorial it is not required as we set a static address in the VM itself
 
−
 
 
−
press OK to save and close until you are back to Virtualbox Manager interface again.
 
−
Network Settings
 
−
 
 
−
Open the VM's settings
 
−
 
 
−
Go in the Network tab
 
−
 
 
−
configure Adapter 1:
 
−
 
 
−
    with Host-only Adapter
 
−
    select vboxnet0 as (adapter) Name
 
−
    click on Advanced and in Adapter Type select Intel PRO/1000 MT Desktop
 
−
    Promiscuous mode should be set to Deny unless you have good reasons to enable it.
 
−
 
 
−
    Configure Adapter 2
 
−
        with NAT
 
−
    (optional) Configure Adapter 3
 
−
        with Bridged Adapter
 
−
        in the Name field select the name of the network card (ethernet or wifi) of your PC that connected to a local network. On Windows it has a full device name, on Linux it will have codenames like eth0, eth1 for ethernet or wlp2s0 for wifi.
 
−
        Click on Advanced and do the same you did for Adapter 1's advanced options
 
−
 
 
−
VM Settings
 
−
 
 
−
:!: due to limitations, the keyboard in the VM's terminal screen is set as US, so some (or most) of your keys will not print the right symbols.
 
−
Also, due to the fact that what you see there is a bare machine terminal and not a smart thing like a ssh program (Putty/Kitty/whatever) or a terminal emulator program, you cannot copy-paste text into it.
 
−
Don't worry, most of the setup will be done after you are connected with SSH (remote terminal) that does not have any of these issues.
 
−
Look at this US keyboard layout to find what button you need to press on your keyboard to generate the right symbol.
 
−
 
 
−
    Boot into your VM
 
−
    Wait 4 seconds for GRUB to boot automatically
 
−
    Press Enter to activate the console when the boot messages have finished to scroll by. It may take two or three minutes for “entropy” to be generated (random: crng init done with OpenWrt 17.01.4). Until there is sufficient entropy, ssh and other cryptographic functions may fail.
 
−
    let's see the current network configuration
 
−
 
 
−
    root@openwrt:~# uci show network
 
−
    network.loopback=interface
 
−
    network.loopback.ifname='lo'
 
−
    network.loopback.proto='static'

−
    network.wan6.ifname='eth1'
 
−
    network.wan6.proto='dhcpv6'
 
−
 
 
−
Note that the default LAN address of 192.168.1.1 is present on first boot.
 
  
−
    edit the network configuration to allow SSH access by writing these commands and pressing enter:
+
* Memory Size > Next
−
        uci set network.lan.ipaddr='192.168.56.2'
+
* Hard Disk > Use an existing virtual harddrive file > Select
−
        uci commit
 
−
        reboot
 
−
    now your VM should be accessible from SSH, user root (no password) address 192.168.56.2
 
−
    after you have logged in successfully, we can actually do the true configuration, please copy-paste the following block of code and press enter:
 
  
−
    uci batch <<EOF
+
Boot ke mesin OpenWRT, cek
−
    set network.mng=interface
 
−
    set network.mng.type='bridge'

−
    set network.mng.netmask='255.255.255.0'

    set network.wan.ifname='eth1'
 
−
    set network.wan.proto='dhcp'
 
−
    EOF
 
  
−
    now write uci changes to check if the setting configuration was loaded correctly. If you see the following (the network.mng entries MUST be the same as the ones shown here, the network.wan might be slightly different), everything went well

    close and open again the SSH terminal when the VM has restarted, with same connection parameters (user root and 192.168.56.2)

    you can now install packages to this images as normal, you will probably want to install luci, write opkg update && opkg install luci, then you can connect to the VM's luci by typing 192.168.56.2 in your browser address bar or click on this link to get there.

Untuk menginstalasi OpenWRT image ke VirtualBox. Asumsinya adalah, 

openwrt-x86-64-combined-squashfs.img

Note default LAN address 192.168.1.1 saat booting pertama kali, bisa di ubah menggunakan misalnya 

uci set network.lan.ipaddr='192.168.56.2'
uci commit
reboot

VM bisa di akses dengan SSH, user root (tanpa password) ke address 192.168.56.2

Setelah login kita dapat melakukan konfigurasi sebenarnya, misalnya 

uci batch <<EOF

set network.mng.type='bridge' 
set network.mng.proto='static'
set network.mng.netmask='255.255.255.0'

delete network.lan
delete network.wan6
set network.wan=interface
set network.wan.ifname='eth1'
set network.wan.proto='dhcp'
EOF

Tulis uci changes konfigurasi harus sama dengan di atas 

root@openwrt:~# uci changes

-network.lan
-network.wan6
network.wan='interface'

Jika semua OK, save config dengan 

uci commit
reboot

Jika tidak, kita bisa reboot sebelum melakukan uci commit

Untuk bridged adapter di adapter 3, kita bisa melakukan 

uci batch <<EOF 
set network.lan=interface
set network.lan.ifname='eth2'
set network.lan.proto='dhcp'
EOF
uci commit
