Comment:

 We solved something similar at Zmanda, where we ran builders on a
 massively oversubscribed ESXi host.  There were a dozen or more VMs, but
 realistically only two could build at once.  What we did is to customize
 the buildslave's `canStartBuild` method.  The only tricky bit is that you
 need to call `master.botmaster.maybeStartBuildsForSlave` any time a slave
 might be able to start a build (so, when a build on another slave on the
 same ESXi host finishes).

 Dan Locks may be able to share some of this config with you.
