image_properties_default_architecture is only used in the scheduler 
filter to pick a compute host, it doesn't do anything about the qemu 
binary used in nova-compute. mnaser added the config option so maybe he 
can share what he's done on his computes.

Do you have qemu-system-x86_64 on non-x86 systems? Seems like a 
package/deploy issue since I'd expect x86 packages shouldn't install on 
a ppc system and vice versa, and only one qemu package should provide 
the binary.
