I think thats an emulated machine problem which I'm just takin care of.=
=0A=
=0A=
to check:=0A=
=0A=
go to cluster, select your cluster, got to the genral subtab and check=0A=
what is "emulated machine" value=0A=
I guess its null. to make it work,=0A=
1.take one of your host which belongs to that cluster to maintenance=0A=
2.activate it back.=0A=
3. check the emulated machine value is set now=0A=
=0A=
cause:=0A=
Bug https://bugzilla.redhat.com/1004695=0A=
Editing the cluster nullify the emulated machine value=0A=

Hello,=0A=
=0A=
thanks for helping me through that minefield. Ok here are the results =0A=
when following your guide.=0A=
=0A=
- Emulated machine: pc-1.0=0A=
- maintenance/activate one node of the cluster:=0A=
- Emulated machine is still: pc-1.0=0A=
=0A=
I guess that is nothing you wanted to see. So I changed the CPU=0A=
type of the cluster and was able to understand what you think of. =0A=
The emulated machine will go blank. After reactivating a node=0A=
the value goes back to pc-1.0=0A=
=0A=
I played with the cluster settings in between and cannot say if the=0A=
value was empty when the error occured. Just in case the emulated =0A=
machine value was empty during restart of ovirt-engine. Did I loose =0A=
the machine because of that? As I'm testing that is no problem but =0A=
I want to make sure if I can recover from that situation in any way.=0A=
=0A=
Best regards.=0A=
