James,

Here at Puppet, we've built a tool called 'vmpooler' which performs this
function[1]. Currently it is written to work primarily with VMware, but
we are very interested in extending it such that we could have pluggable
backends (perhaps even on a per-pool basis).

Please feel free to take a look, fork, and modify. Of course, PRs are
always welcome. =]
