From: Boris Fiuczynski <fiuczy(a)linux.vnet.ibm.com>
In the DefineSystem call the architecture, machine and emulator for KVM are set
to the hypervisor-specific default values if they did not get provided.
This now allows architecture based decision making in the CIM providers to
work for all platforms.
