It occurs for both --raw=/dev/sde and for disk image files. Below is from a disk image file:

After more debugging and digging I have found the bug to because I am using grub2 on this host as grub1 doesnt play nice with the cutting edge dell machines in our lab, and our lab deployment software (another story).

What I have done is extract the grub binary from the deb package and modified /usr/lib/python2.5/site-packages/VMBuilder/plugins/ubuntu/distro.py to point to my manually extracted grub executable.

If I can get some time I will try and make the VMBuilder play nice with grub2, but it appears grub2 lacks any sort of --batch functionality.

This happened to me, too. I was using lilo.

If this package depends on grub, it should probably be advertised somewhere.
