I think that within an OpenStack cluster you'd have to dedicate a whole 
compute node to running ppc64 and have it advertise the architecture as 
ppc64.  Then when you ask for "architecture=ppc64" it should land on 
that node.

If this is for "development, testing or migration of applications to 
Power" have you checked out these people?  They provide free Power VMs.
