This isn't really anything todo with KVM - it is a more general
requirement. If no architecture is given in the XML, we must
always default to the host architecture, whether using QEMU TCG
or KVM.
It looks like your code handles this fine, but the test case you
added is only checking kvm, so might be nice to also validate
the QEMU case too.
