Ok, looks like your DHCP request is taking a bit more time to be served
than in setups I have used.  I guess starting your script with a wait
loop such as:

   while (! ping -c 1 dk.archive.ubuntu.com); do sleep 1; done

will make sure DHCP has finished its job before going any further.

Well, it clearly does not in your case. Once you have verified that the
above solution does work, if you can let us know or update the wiki page
[1] which serves as a source for the documentation, it will definitely help.

The wait loop could indeed be put in the calling script that vmbuilder
installs...  Let's discuss that in your bug.
