I'm not sure if this is the correct place to post this or even if anyone would be interested in this, but I spent some time yesterday working with the Ice Cream Sandwich source and was able to get Android compiled for VirtualBox. This is virgin AOSP using the included 'vbox-x86' make target, so there were no changes made to the source. I thought some people may just want to see ICS and tinker rather than go through some of the hoops so I decided to release the VM.
PLEASE NOTE THAT I WILL NOT GIVE ANY SUPPORT FOR THIS.
At the link below are some screenshots of it running in VirtualBox as well as the link to download.
UPDATE... Since I'm a newb (never posted but been here for a while), I can't post the link. But, here are some screenshots. Perhaps I can get external links approved from the moderators?
