[Libvirt-cim] about 'CreationClassName' key in VirtualSystemIsMigratableToHost method

I think this is probably a reasonable instance where such a check
actually adds value.  Assuming you have two domains called "meep", one
a KVM domain and another a Xen domain, you could potentially pass a
reference of the Xen one to the KVM_VirtualSystemMigrationService.
This would result in moving a different domain than intended.
Granted, this would be a client error, of course, but it seems like
something we could easily help prevent from the provider side.

Thanks!
