+Disable extlinux installation and configure grub2 instead. grub2 will be added to
+the list of packages to install. update-grub will be called once the debootstrap is
+complete and grub-install will be called in the image. Versions of grub2 in wheezy
+can fail to install in the VM, at which point vmdebootstrap will fall back to
+extlinux. It may still be possible to complete the installation of grub2 after
+booting the VM as the problem may be related to the need to use loopback
