for horizon to add filter on migration so that we only see hosts that are compatible for migration we need nova to create a check on cpu compatibility.

From what I understand, you are asking to add a feature to the novaclient library that would first validate cpu compatibility (perhaps through the hypervisors api[0]) before forwarding the migration request on to nova. Please add more detail to this bug if that is not the case.
