The platform device can be created either in mc->kvm_type or manually (not sure if it makes sense to have a "XenVMMXenVMM" CPUID + emulated hypercalls but no platform device---would it still use pvclock for example?).
Not sure it's wise but the platform device is certainly optional in xl.cfg so you can easily bring up a VM without it.
