I think that's an emulated machine problem which I'm just taking care of.

to check:

go to cluster, select your cluster, got to the General subtab and check 
what is "emulated machine" value

I guess its null. to make it work,
1.take one of your host which belongs to that cluster to maintenance
2.activate it back.
3. check the emulated machine value is set now

cause:
Bug https://bugzilla.redhat.com/1004695
Editing the cluster nullify the emulated machine value
