Unity 3D from 11.04 runs fine in Virtual Box >=4.0.6 as tested with NVidia proprietary graphics driver on the host. 3D support is activated by installation of Guest Additions.
A useful approach to testing the next releae, 11.04 is to create a live Ubuntu system on a USB memory stick from the daily builds:

Unity is not the default desktop environment yet, but is scheduled to be so by Alpha1 on the 2nd December as far as I understand the release schedule: https://wiki.ubuntu.com/NattyReleaseSchedule
As well as testing Ubuntu a Live USB stick, you can also use that live USB stick to install Ubuntu 11.04 onto a second USB stick, selecting manual partition during the install.
You can also use TestDrive to automate testing when Ubuntu 11.04 Unity desktop does work in VirtualBox.
Thank you
If all you want to do is experience it,rather than a Virtual machine, use the live CD
