we're forgetting jenkins slaves, we'll want to create a few vms with various 
OS (f17,f18,rhel63,rhel64...) 

best practise is not to run any jobs on the master node, but i assume we can run some maven jobs
on it until we'll set up more slaves.

btw, are we going to use the existing amazon vms as slaves for the new jenkins master?
at least for starts?

jenkins no - uses only local xml files
gerrit - yes (git + db)
