Thanks for reporting this bug and helping to make Ubuntu better.
Are you able to boot from an install .iso, install a VM, and reboot into that working VM? In other words, is it only images built by vmbuilder which fail to boot?
Can you give us the precise vmbuilder command you are using to create the VMs which do not boot?
