Open Stack

Well first of all, we are using a deployment system which will not support
your system.  That is by far the #1 blocker (we are using Razor/Puppet).
 Live migration isn't something we "need" today, but the ability to rebuild
our cluster in a matter of an hour is.  This is why We can't really get
into XCP
