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=

Hello,
thanks for helping me through that minefield. Ok here are the results
when following your guide.
please provide the output of:
psql engine postgres -c "select * from async_tasks;"
- Emulated machine: pc-1.0
right, you restart the engine so the host already was
reactivated so
this is actually expected.
- maintenance/activate one node of the cluster:
- Emulated machine is still: pc-1.0
I guess that is nothing you wanted to see. So I changed the CPU
type of the cluster and was able to understand what you think of.
The emulated machine will go blank. After reactivating a node
the value goes back to pc-1.0
I played with the cluster settings in between and cannot say if the
value was empty when the error occured. Just in case the emulated
machine value was empty during restart of ovirt-engine. Did I loose
the machine because of that?
no this can't lead to that but the restart of
ovirt can.
Yair, seems like importVM task is still in the DB after an engine
restart during run VM fail.
As I'm testing that is no problem but
I want to make sure if I can recover from that situation in any way.
Best regards.
Markus

This exact thing is happening to me. I'm trying to import oVirt 3.2 VM's from an
export domain. The import is successful, to the point I can fire up the VM's.
Restart ovirt-engine and the VM is gone. Prior to the latest ovirt-engine update, only
the VM container was removed and the disk remained. Since updating to
ovirt-engine-3.3.0-3.el6.noarch a few moments ago, the container still gets removed, but
now the disk is gone too!
