I never fully solved these problems. Even with the vmbuilder patches,
the Ubuntu VMs would spin with 100% CPU at the BIOS screen, not even
allowing SSH. But the preparation of the VMs was the only problem. I
installed a fresh Ubuntu 14.04 on another computer, used it to build the
VM images, copied the images to the build host that was giving me
trouble before, and then I was able to complete a build.
