- install puppet 
- take the svn of admin 
   svn co svn://svn.mageia.org/adm/ /etc/puppet/ 

and then something like :
puppetd --test --tags buildnode 

( not sure about this )

However, I do not recommend this, as I think what maarten want is to
have iurt, not the whole scheduling system and upload system of the
build system.

Well our buildnode run on mandriva, your vm will likely be a mageia. So
that's already a difference.

Well, if puppet is started and start to put our ssh keys as root, yes,
we will have access to the vm, provided that 1) we have network access
2) time to lose on this ( neither are credible possibility ).
