This can now be done because previous commits added support for Intel VMX migration. AMD SVM migration is still blocked. This is because kernel KVM_CAP_{GET,SET}_NESTED_STATE in case of AMD SVM is not implemented yet. Therefore, required vCPU nested state is still missing in order to perform valid migration for vCPU exposed with SVM.
