You should give an example , as it's not clear enough.

[ovirt-users] Re: Should I migrate existing oVirt Engine, or deploy new?

[David White via Users]

Hi Paul,
Thanks for the response.

I think you're suggesting that I take a hybrid approach, and do a restore of 
the current Engine onto the new VM. I hadn't thought about this option.

Essentially what I was considering was either:

-   Export to OVA or something
OR
-   Build a completely new oVirt engine with a completely new domain, etc... 
and try to live migrate the VMs from the old engine to the new engine.


Do I understand you correctly that you're suggesting I install the OS onto a 
new VM, and try to do a restore of the oVirt settings onto the new VM (after I 
put the cluster into Global maintenance mode and shutdown the old oVirt)?

[Staniforth, Paul]

Hello David,
  I don't think there's a documentated method to go from a 
Hosted Engine to standalone just the other way standalone to HE.

I would suggest doing a full backup of the engine prepare the new VM and 
restore to that rather than trying to export it.
This way you can shut down the original engine and run the new engine VM to 
test it works as you will be able to restart the original engine if it doesn't 
work.

Regards,
Paul S.

[ovirt-users] Should I migrate existing oVirt Engine, or deploy new?

[David White via Users]

Hello,
I have just purchased a Synology SA3400 which I plan to use for my oVirt 
storage domain(s) going forward. I'm currently using Gluster storage in a 
hyperconverged environment.

My goal now is to:

-   Use the Synology Virtual Machine manager to host the oVirt Engine on the 
Synology
-   Setup NFS storage on the Synology as the storage domain for all VMs in our 
environment
-   Migrate all VM storage onto the new NFS domain
-   Get rid of Gluster


My first step is to migrate the oVirt Engine off of Gluster storage / off the 
Hyperconverged hosts into the Synology Virtual Machine manager. 

Is it possible to migrate the existing oVirt Engine (put the cluster into 
Global Maintenance Mode, shutdown oVirt, export to VDI or something, and then 
import into Synology's virtualization)? Or would it be better for me to install 
a completely new Engine, and then somehow migrate all of the VMs from the old 
engine into the new engine?

Thanks,
David

[ovirt-users] Re: Selecting login profile with LDAP integration

[Patrick Hibbs]

If you followed an older guide, what you've probably done is setup the
deprecated aaa plugin. New installations use keycloak by default, which
has it's own setup method for integrating an LDAP authentication
source.

It is possible to use the older plugin system, but it won't be
supported moving forward and is liable to be removed entirely. I can't
recommend it's use.

There is a link to a guide on configuring keycloak integration on the
mailing list:
https://lists.ovirt.org/archives/list/users@ovirt.org/message/UMG3BB5I4T5AGPWY2XABNFJUOQVBIIGV/

That being said, it's probably possible to enable the deprecated
interface on a new installation, but I'm not sure how to do it. You
might get an idea or two from the link above however. (The external
keycloak guide.)

As for the other interfaces, there was a comment a while ago about how
email addresses can wind up looking weird with keycloak integration.
Specifically, if a user's email address is used ( b...@example.com ) it
can require having the auth source appended ( b...@example.com@example-
authz ) during login for it to work. You might want to give that a try
first.
