Has anyone tested a beta of Ubuntu 11.04 with the new Unity desktop (requires 3D) ?

Yes and it works well. You will be able to run it in the next maintenance release of VirtualBox soon.
Yes it requires 3D and from what I hear you may even be able to run it now using the GA version of VirtualBox from the Ubuntu repo.

I have 3D enabled and 32 MB of video RAM and have tried VB Guest Additions and OSE Guest Additions in the latest VB 4.0.6r71416 on Windows 7 x64.

Natty 32 bit does not boot into Unity for me ...

Update - I had to install unity-2d to get it to work.

sudo apt-get install unity-2d

I have VirtualBox 4.0.6 in a Windows 7 x64 host, and the guest system is Ubuntu, with Guest Additions installed.

I updated yesterday the Ubuntu 10.10 to 11.04 using the built-in upgrade process. The result was that I got locked out of the system. The upgrade process processed ok and finally the Ubuntu 11.04 booted showing the first glimpse of the graphical background, but the login screen never materialized and the empty screen was all I got to see. After exprimenting a bit I found out that the system responded to ACPI shutdown etc., so it was ok in principle. But no login screen, just an empty screen.

After some thinking, I guessed that the reason might be incompatibility between the updated Linux kernel and the already existing VirtualBox GuestAdditions 4.0.6 (built for the pervious kernel version) that had survived the upgrade. So, perhaps a re-install of the 4.0.6 Guest Additions would help?

I solved the problem by getting into the console mode (Ctrl-Alt-F1) and logging into Ubuntu from that console, then I manually created a mount point for the cdrom and mounted the Guest Additions cdrom, and finally did run the Guest additions script. That solved the problem.

sudo mkdir /media/cdrom
sudo mount /dev/cdrom /media/cdrom/
sudo /media/cdrom/VBoxLinuxAdditions.run

So, it might be advisable to uninstall Guest Additions before the upgrade from 10.10 to 11.04, as the old version might prevent the upgraded system to boot properly into desktop.

Ps. After enabling the 3D accleration in VirtualBox guest system settings, the Unity booted ok, but I decided to stay with the old classic desktop for the time being.

i did also try the new ubuntu with unity.
when you are finished with the installation you are only able to use the old GUI. you have to install dkms and the vbox guest additions and then after a restart you are able to use the 3D unity GUI.

Thanks, prickly.

The unity-2d command got it working for me.

Yeah, it works fine.

How did you start the 3D GUI after installing GA?When I rebote I only get Classic GUI...

Edit:Nevermind I enabled the 3D and i started with 3D GUI.
Anyway I think I like 2D better...

You select it at the logon screen. look at the bottom of the screen ans change the session.
