Ubuntu P2V won't boot (ureadahead main process terminated with status 5)

Hi,

I'm trying my first experiment with P2V, creating a VM on ESXi 4.1 of an Ubuntu 10.04.2 LTS machine.  The conversion runs fine (although I do have to resize my partitions to make them small enough for my datastore's block size), but the installed Ubuntu on the VM doesn't boot.  It just displays the error:

init: ureadahead main process (<pid#>) terminated with status 5

I've tried with Conveter versions 4 and 5 with the same result.  Is there a step I'm missing?  Maybe something I need to do to fix the fstab?

Thanks.
