Not sure about this. Are you proposing this for 4.1? Should be OK I guess.

Figured it out: the dhcp server in vbox hands out the dns server of the
host (in my case my corporate dns server). Dhclient reverse looks up (the address of the vm) and gets a valid response from the
corporate dns server. Annoyingly this is used to name the volume group
during partitioning. The only foolproof way may be to write a custom
partman recipe in preseed.cfg. You can change the ip of the vm using
:vm_options in veewee but veewee's http server is hardcoded to so
nothing else works.

Well veewee doesn't let you write custom scripts that execute on the host?
Anyway, I figured we can use debconf-set-selections to avoid this problem.
As far as copying the custom scripts goes, perhaps we can wget from repo ?

I've left a few FIXME in, please take a look.
