This information is a little hard to find on the Internet. This is how to install Android 4.0 (Ice Cream Sandwich) in VirtualBox, in a "do it yourself" way (installing from an ISO image). There are some people who have made pre-installed VirtualBox images, but one problem you may run into going that route is that the Android serial number will match everybody else who's using the same image as you, since Android generates this number on its first boot.

First of All

(Update 9/3/13) Apparently, the official Release version of Android 4.0 from android-x86.org should work completely out-of-the-box in VirtualBox: android-4.0-r1. I have an older development release linked later in this post that was built specifically for VirtualBox, which is what this post was originally written about. The Release version of Android 4.0 also contains Google Play and the other Google apps out of the box, so you can skip the part about installing th
e Google apps later. Thanks @DrDeve for pointing this out!
(Update 8/30/13)
This blog post is about a very particular build of Android 4.0 that is linked to later in this post. The instructions that follow are known to work when installing from that ISO image. There does exist Android 4.3 ISOs from android-x86.org and when I tested them, a lot of stuff seemed to just work out of the box in VirtualBox, but this blog post isn't about Android 4.3.
Also, if you're using a different Android 4.0 ISO you found somewhere else, there's no guarantees it will work very well for you. Networking and audio are some of the biggest problems I've seen in Android virtualization. So, before you ask me for help with installing or getting the networking to work (hint: networking should just work with no extra fuss), make sure you're actually using the ISO image linked later in this blog and not some other random one. The one I have was designed specifically for VirtualBox and it works.

Getting an Android ISO

Update (9/3/13): The final 4.0 release by Android-x86 is available from android-x86.org, and it should work completely out-of-the-box in VirtualBox and includes Google Play and the other Google apps. You should probably download it from there instead of the older development version I link to below. The folks at Android-x86 have been making x86 builds of the Android OS for quite a while now, and none of this would be possible without them. They have ISO images for various versions of Android available, but most of them don't work very well in VirtualBox. For example, their "eeepc" image for Android 4.0 has issues with the audio drivers and the network (it has no Ethernet support built in, etc.)
So this means using one of the Android-x86 images from there won't get you too far because audio and networking won't work. Fortunately, somebody has put together an ISO image that's been custom tailored to VirtualBox.
I don't remember where I found this ISO image; if it's yours, leave me a comment and I'll edit this post. ;)I found the ISO here: android-x86 VirtualBox/VMWare support (thanks @jakimfett!)
I have a copy of this ISO hosted here: android-x86-vm-20120130.iso (244MB). This ISO works much better.

Create a Virtual Machine

In VirtualBox, create a new machine for Android.
  • Machine Name: "Android ICS" (you can name it anything you want)
  • Machine Type: "Linux 2.6"
  • Memory: I gave my VM 1024MB of memory.
  • Hard Disk: I created a new 16GB VDI image that dynamically expands.
All the default settings worked fine for me. Here's what the defaults were on my system:
  • Networking:
    • Type: NAT
    • Adaptor: "Intel Pro/1000 MT Desktop (82540EM)"
  • Audio: Intel AC'97
  • Storage Layout:
    • IDE Controller:
      • CD Device
    • SATA Controller:
      • Hard Disk
Update: In the comments, @Ni mentions this:
Make sure you add the SATA Controller if it does not appear, when you setup the virtual box and then add the ISO image and virtual disk image to this. If you try and add the ISO image and virtual disk image to the IDE Controller this will not work at. This information maybe useful to someone making this mistake.
It worked for me as listed above (IDE CD drive, SATA hard disk), but this is something to keep in mind if you have any issues booting the CD or installing it to disk.

Installation

Make sure the VM boots from the ISO image.
  1. On the boot screen, select "Installation - Install Android-x86 to harddisk"
  2. Choose "Create/Modify Partitions". This takes you into cfdisk.
    1. Choose "[New]"
    2. Choose "[Primary]"
    3. Press enter to accept the default partition size (mine was 17174.38)
    4. Choose "[Bootable]"
    5. Choose "[Write]"
    6. Type "yes" to confirm writing.
    7. Choose "[Quit]"
  3. Choose to install on the sda1 device (Linux VBOX HARDDISK)
  4. Choose to format the drive "ext3"
  5. Pick "Yes" to confirm formatting.
  6. Pick "Yes" when it asks to install the GRUB bootloader.
  7. Pick "Yes" when it asks to mount /system as read-write (this will be important later to install the Google apps).
  8. Create a fake SD card when it prompts. I made mine 2047MB (the maximum allowed).
  9. Choose "<Reboot>"
Make sure you detach the ISO image from the virtual machine so that it will boot into the installed OS. If you see the "Installation" option again, it means you're booting from the ISO still!

Note About Internet Access in Android

(Update: 9/3/2013): @DrDeve commented about the network settings for VirtualBox/Android:
Internet not working is often because the kernel has no driver for your NIC and / or you are in bridged mode The AMD-PCnet is the standard for virtual drivers for VB and VMware - including the heavy iron VmWare ESX -- no matter what you have installed switch VB settings to the PCnet driver and use NAT -- IT WILL JUST WORK IF YOU DO! Native drivers often dont start until you open VB settings box - quirky -- use the de-facto standard PCNET NIC driver.
(Update: 8/30/2013) This is a common question people have, is how does the Android VM's connection to the Internet work? I'd refer you to the VirtualBox documentation about networking, but briefly: configure your guest OS's network to use NAT mode. This is the simplest way to do it.
What happens in NAT mode is, Android will boot up, see an imaginary router handing out IP addresses, and get one. And, it doesn't matter what your real life network layout looks like (whether your physical computer is connected to Ethernet, Wifi, a 4G LTE dongle, dial-up modem, VPN), the Android virtual machine will always think it's connected to Ethernet. So, questions of "how do I connect to my Wifi?" don't make any sense when you understand how VirtualBox (and most other virtualization systems) work. If your host computer has an Internet connection, the virtual machine should have it as well, automatically.
This may be a bit confusing for Android users though because Android typically doesn't use Ethernet. The lock screen in the Android VM will say "No Internet connection", and in your settings, Wifi will probably be turned off and resist turning on. Completely ignore both of these things. The VM is using Ethernet for its connection, so just try opening the web browser and point to kirsle.net or something and see if it loads.

Tips for Running Android

You'll want to disable mouse integration to be able to interact with the GUI at all. This can be done from choosing the "Machine" menu in the VM window and clicking "Disable Mouse Integration" -- or pressing HostKey+I. The Escape key on your keyboard corresponds to the Back key in Android. The context menu key on your keyboard corresponds to the Menu button in Android (the context menu key is usually next to the right Windows key).
To power off the VM, press HostKey+H. This will cause Android to pop up the shutdown dialog that you'd expect on a real phone. You can also use the "Machine->Send Shutdown Signal" to do the same.
Update (9/3/2013): @DrDeve mentions how to get out of the lock screen when Android's Powersave kicks in:
OK, one more thing I forgot -- Powersave For some darn reason you cant bring a VB ICS 4.0.4 build out of powersave (hybernation for my Windows friends) by clicking on the video screen.
So if your VM goes into lockscreen while you are playing a game or something, after stopping for about 2 min (time to lock is configuratble in Settigns)
You will need to press on the right menu key several times, once only shows a lockscreen "ping"
the menu key is the key between the right hand alt and Ctrl keys on most modern keyboards
have fun

Install the Google Apps

NOTE: You can skip this step if your Android ISO already included the Google apps out of the box. (Updated 9/3/13) You may notice that this Android VM doesn't include the Android Market, GMail, or Google Maps. These are some of the Google Apps and due to some licensing restrictions Android-x86 doesn't include them "out of the box".
On a real Android device that's been rooted and flashed with a custom ROM, you'd install the Google apps by flashing them in recovery mode. But you can't get into recovery mode on VirtualBox. Thus, the method for installing the Google Apps is kinda sketchy, but it works (and if you know of a better way, feel free to tell me).
You'll need a file with a name like "gapps-ics-20120304-signed.zip". These are the Google apps (the date part might be different). You can Google them, but I have a copy of them here to download too.
You don't really need the entire Google Apps file, actually. Just the "system" folder inside the zip file. Create a new tar file of the "system" folder so that it will be easy to get it into your Android device. I have a prepared "system.tar.gz" for you if you just want to use mine.
The steps to install the Google Apps are as follows:
  1. Download system.tar.gz to your Android VM somehow. I used the Web Browser app and downloaded it there. You could probably also use the Email app, or if you're really Android savvy, push it with the Android Debugger.
    • If Android tells you that there is no SD card so it can't download the Google Apps, that's because you skipped that step while first installing your Android system. The very last step of the installer asks if you'd like to create a virtual SD card partition, and you should've had it do that. If you didn't, the only easy solution I know of is to reinstall the OS.
  2. Open the "Terminal Emulator" app in Android.
  3. Enter these commands (note: don't type the $ or # symbols at the beginning of these lines. These symbols indicate the prompt.) 
    $ cd /sdcard/Download
$ tar -xzvf system.tar.gz
$ su
# cd /sdcard/Download
# cp -rf system/* /system/
    Pay special attention to the cp -rf command. Make sure the slashes and *'s are in the right places.
  4. Reboot the phone.
You should now see the Market app, GMail and the others in your app menu. Note: in my experience, the Market app will be somewhat unstable. When you start the app, it will Force Quit after 10 or 15 seconds. However, if you're fast enough you should be able to quickly search for a specific app you'd like and begin the download process before Market crashes, and the app will continue to download and install regardless.
I imagine that the unorthodox way of installing the Google Apps might be partly to blame for the Market being unstable. The other Google apps seem to work fine though.

Custom Screen Resolutions

This is a tip I discovered somewhere a while back for getting custom resolutions to work in your Android VM (for example, to mimic the screen dimensions of the Galaxy Nexus phone, or just to run the VM at a higher resolution like 1024x768). I've found that you can use just about any arbitrary resolution you want, but when the resolution isn't a standard 4:3 one (like 1024x768), the VM seems to get somewhat laggy. The general steps are as follows. Substitute 1024x768 with whatever resolution you want. You can add multiple video modes by changing "CustomVideoMode1" to be "CustomVideoMode2", etc.
  1. In your Terminal or Command Prompt window on the host system, run this command:
    VBoxManage setextradata "Android ICS" "CustomVideoMode1" "1024x768x32"
    Substitute "Android ICS" with the name of your VM (but keep the quotes).
  2. Start your Android VM, and when you see the bootloader screen:
    1. Press the "e" key to edit the boot arguments
    2. Press "e" again to edit the kernel boot line
    3. Add UVESA_MODE=1024x768 to the end of the boot arguments (make sure to hit Space first), and press Enter.
    4. Press "b" to boot.
There should theoretically be a way to edit the GRUB config file and add more boot options that have the custom resolutions already configured, but I'll leave that as an exercise for the reader. :) Update (9/3/2013): @DrDeve mentions in the comments:
If you install GRUB bootloader you can hit e to edit like you say, or a, then press space and type vga=ask then press enter. a long list of VESA modes (and the color bits from 8-32) will be displayed. Not all will ork, so selecting one here, resetting the VM if it doesnt work BEFORE editing the config files may save you from bricking your new toy!
Each entry is a thre char hex value, follwed by the resolution, like 1024x768x32, etc.
Once you find a mode that works, THEN modify the config using the hex value that worked using the methods above.
You can als edit the GRUB menu.lst to add the value from the sceen above
- convert the hex value that worked to decimal (i.e. 360 becomes 864, etc).
- open terminal
- su
- cd /mnt/grub
- vi menu.lst
- add vga=864 to the end of the line that startes with &quot;kernel&quot;, or if one is there, modify it
- save the file by entering :wq
if you havent used vi before you might need a guide open beside you look here http://www.cs.colostate.edu/helpdocs/vi.html

No Warranty

Android is primarily an ARM architecture operating system and the x86 version isn't supported by Google. While a lot of apps will work in Android-x86, some may crash in weird ways. If you're an Android developer though, this can be pretty useful because Android-x86 will run a lot faster on your hardware than the standard emulator from the SDK does, so you can test your apps much more rapidly (the Android-x86 site has some documentation on how to connect ADB to your virtual machine). Your mileage may vary.

Updates

To answer common questions that come up in the comments...
  • Adobe Flash, Netflix, others... -- these apps won't work in Android-x86, because they aren't pure Java. They include C code that's compiled for the ARM processor found in most Android devices. They won't run on x86 processors.
  • Apps that rotate your screen... -- apps that force the orientation into portrait mode (thus turning your screen sideways) can be dealt with by changing your VM's screen resolution to be taller than it is wide (i.e. 800x1280). The app will recognize the portrait resolution and not rotate. However, your VM may be laggy when it's not in a standard 4:3 resolution. Alternatively, find an app that forces/locks your orientation to one direction or another -- however, some apps misbehave when forced to use the wrong resolution and may not be usable.
  • Don't expect a lot of apps to work -- for various reasons, apps that work on real Android devices may not function properly on Android-x86.
  • Text messaging and phone calls won't work -- Your virtual machine is not a phone. It doesn't have a cellular connection to AT&T or Verizon or anybody. The standard texting apps like Messaging and Handcent SMS are useless on an Android VM (this also goes for most Android tablets that don't have cell connections). If you want to text from your VM, you might try using the Tablet Talk app, connect it with your actual cell phone, and text through that app. If you want to make phone calls, you might have luck with a Voice over IP app -- however, I can't guarantee your microphone and such will work with the VM, as I haven't tested it.
I'll update the list above as more common questions come in from the comments below.
