Hello oVirt Forum members:
We are currently using oVirt Version 3.5.0.1-1.el6. We tried to migrate to=
use hosted-engine model.
Somehow the hosted-engine got created, but the migration failed. So I ran =
engine-setup to remove the installation. However, I am now leave with a VM=
entry in our oVirt console called HostedEngine. Tried to remove the entry=
by clicking on the Remove button on the console gives a message:
Error while executing action:
HostedEngine:
Cannot remove VM. This VM is not managed by the engine.
As far as I can tell, all files that were touched by the hosted-engine are =
reverted back to before install state. So I am not sure where that HostedE=
ngine entry is coming from. Is that a record in the database that I need t=
o clean up manually from the db?
Any advice is appreciated.
Thanks,
Eric

Subject: [ovirt-users] Clean up Hosted Engine entry in oVirt console
Hello oVirt Forum members:
We are currently using oVirt Version 3.5.0.1-1.el6. We tried to migrate to
use hosted-engine model.
Somehow the hosted-engine got created, but the migration failed.
Please give more details, it's not completely clear what you did.
Let's define:
oldenginemachine - the machine where you ran the engine before migration attempt
hostedenginehost - the host where you tried to run hosted-engine --deploy
newenginemachine - the vm created by 'hosted-engine --deploy' where you were
supposed to setup an engine (by migrating data from oldenginemachine)
Was hostedenginehost registered in oldenginemachine before? Or is it a new
host?
Was the engine there down while you tried migrating?
Is there a chance that it was up, and 'hosted-engine --deploy' connected to
it and tried doing stuff there?
So I ran
engine-setup to remove the installation.
Where?
However, I am now leave with a VM
entry in our oVirt console called HostedEngine.
You mean, in oldenginemachine?
Tried to remove the entry by
clicking on the Remove button on the console gives a message:
Error while executing action:
HostedEngine:
Cannot remove VM. This VM is not managed by the engine.
Indeed.
As far as I can tell, all files that were touched by the hosted-engine are
reverted back to before install state. So I am not sure where that
HostedEngine entry is coming from. Is that a record in the database that I
need to clean up manually from the db?
Indeed.
Not sure exactly how, but first let's be sure what the problem is.
Best,

Didi:
Thanks for taking the time. Let me try to provide more details. I added my comments
below your questions.
Many Thanks,
Eric

Subject: [ovirt-users] Clean up Hosted Engine entry in oVirt console
Hello oVirt Forum members:
We are currently using oVirt Version 3.5.0.1-1.el6. We tried to migrate to
use hosted-engine model.
Somehow the hosted-engine got created, but the migration failed.
Please give more details, it's not completely clear what you did.
Let's define:
oldenginemachine - the machine where you ran the engine before migration attempt
Our oVirt environment is configured as followed:
- 2 racks. Each rack has 10 blades with SAN storage.
- the 2 racks cannot access the SAN storage of the other rack. So the X side blades can
only reach X side SAN. D side blades can only see D side SAN.
- Application VMs are running on both side of the rack. So in case one side of the rack
completely failed, we still have the other side providing the application services.
- Our oVirt management environment is also configured the same way. X side & D side
has their only ovirt-engine. "ovirt-engine" is running on CentOS VMs.
Ovirt-engine on each side can see the blades and VMs on both sides.
hostedenginehost - the host where you tried to run hosted-engine --deploy
We tried to deploy hosted-engine on one of the blades on D side. We used this doc as our
guide. http://www.ovirt.org/Migrate_to_Hosted_Engine
newenginemachine - the vm created by 'hosted-engine --deploy' where you were
supposed to setup an engine (by migrating data from oldenginemachine)
On that D side blade, we got to the end of Part One of that document in which the
newenginemachine seem to be created but I can never connect to it with vnc or
remote-viewer (no firewall blocking). The hosted-engine is configured to use iSCSI
storage instead of NFS.
Was hostedenginehost registered in oldenginemachine before? Or is it a new host?
I think the installation process automatically registered the hostedenginehost in the
oldenginemachine during the Part One of the setup process. It was not there before.
Was the engine there down while you tried migrating?
The "engine" you talked about here. Is that the new or old one? The new
hostedenginehost cannot be started. The oldenginemachine still runs. When I tried to
started the HostedEngine (hostedenginehost) from the ovirt console, it tells me cannot be
done because it is not managed by this ovirt host.
Is there a chance that it was up, and 'hosted-engine --deploy' connected to
it and tried doing stuff there?
So I ran
engine-setup to remove the installation.
Where?
I ran that on the blade where I initially ran the hosted-engine --deploy
However, I am now leave with a VM
entry in our oVirt console called HostedEngine.
You mean, in oldenginemachine?
That is correct. From the GUI provided by the oldenginemachine, I can see the entry
HostedEngine.
Tried to remove the entry by
clicking on the Remove button on the console gives a message:
Error while executing action:
HostedEngine:
Cannot remove VM. This VM is not managed by the engine.
Indeed.
As far as I can tell, all files that were touched by the hosted-engine are
reverted back to before install state. So I am not sure where that
HostedEngine entry is coming from. Is that a record in the database that I
need to clean up manually from the db?
Indeed.
