Anyone figure out how to get the 32-bit Ubuntu 13.04 beta running as guest in 64-bit Virtualbox 4.2.10? The installation of the guest OS seems to go fine for me, but then once it reboots I'm presented by this screen:
And then an endless loop of this screen:

13.04 and VirtualBox is a little sketchy at the moment. Their LLVM software rendering seems to be in conflict with VBox 3D acceleration. I have a usable copy of 13.04 but need to turn off the VBox 3D acceleration if I want to do anything that uses OpenGL. (it causes the guest to hang if enabled)

That said I have not seen the particular screens you are seeing. Do you know if the Ubuntu (older version) guest additions are installed?

Note: I am using the build from SVN but I also have the standard 4.2.10 and they both seem to work the same in this instance.

No guest additions, this is on the first reboot after the install finished.

I tried both with 3D turned on and turned off to see if it made a difference. Next thing I could try is the 64-bit version of the guest OS, but I specifically was trying to build a 32-bit VM to pass to someone. I think for now I'd rather go back to Ubuntu 12.10 until I see something from Oracle or Canonical about them having fixed something in this area.

That "low graphics mode" message at boot has been a frequent problem for many on Ubuntu 12.10, particularly for people using new fast hardware + SSD (nothing to do with Virtualbox). Search for it in launchpad and you will find stacks of related bug reports. It is due to a race condition in lightdm. The workaround for 12.10 has been to install gdm which replaces lightdm. So you could try that in your guest.

Much to my surprise I have Ubuntu 13.04 (Unity), running perfectly well on my iMac with 3D enabled and working. Ubuntu Gnome 13.04 is another story. It runs, and when it remains running it works fine as well, but it randomly aborts for whatever reason. I did install Gnome 3.8 which is supposed to be an improvement. I don't know if that's the problem or not.

Just noticed something. The virtualbox drive I created is 7gb in size, since Ubuntu 13.04 said it needed 6.x GB to install. I then chose the default installation options, which doesn't display the details of how it will partition the drive.

But by default, it created a 4gb swap partition, leaving only 3gb for the / partition. When I booted to a command-line just now, I noticed the partition is 100% full. Might explain the messed up installation. I'm just about to redo this installation, and this time I wont accept the defaults but will hand-craft the partitions to see if I can get it working. Maybe what I ran into is a simple misdiagnosed out-of-disk-space error.

Bingo, that must have been the problem. Installed without a swap partition, so Ubuntu had access to the entire 7gb drive, and this time it worked perfectly. Installation of 32-bit Ubuntu 13.04 took 2.8G of disk space, and it booted as expected to the desktop.

Sorry for the wild goose chase.
