Batch delete Snapshots
by Christian Reiss
Hey folks,
quick question: Can this be made batch-able?
# gluster snapshot delete all
System contains 1 snapshot(s).
Do you still want to continue and delete them? (y/n)
So for a script I could do a snapshot, copy the contents and auto-remove
all snapshots after. I could go with snapshot list and act on those, but
this seems like it should be in the code?
-Chris.

Keep in mind that I had some issues with oVirt (was more than a year ago - so don't ask for details) when either firewalld or SELINUX were down.
With so much experience in IPTABLES - it's understandable, but keep in mind that in CentOS/RHEL 8 iptables command is just a translator to nftables - with limited capability and I don't think that it was a coincidence . With firewalld you can still achive 90-95% of what you could do in IPTABLES while the rules are quite clear even for a new admin.
What I really like is that you can predefine the ports and protos for a specific service and easily deploy it via salt or ansible.

Safely disable firewalld [Ovirt 4.3]
by francesco＠shellrent.com
Hi all,
I was wondering if it's "safe" disabling entirely the firewalld service and manage the firewall only via iptables, on the host and on the hosted engine (a self-hosted engine). It would make a lot easier the managing the firewall rules for me because of many automatisms I created based on iptables. Did anyone manage to do this? Any contraindication for doing this or precaution that I have to take care of?
Thanks for your time and help,
Francesco

Well, yes and no :)
In order for user to be considered admin (for ovirt engine) it must belong to
keycloak's ovirt-administrator group (in keycloak admin panel see Manage-
>Groups->Members)
I think you are very close to have it up-and-running.

Re: oVirt and KeyCloak intergration
by Anton Louw
Ok so this is definitely looking better. I get an error, but at least now it is saying : “The user admin@openidchttp is not authorized to perform login”
This is strange though, because admin in by default should be allowed access?

These two issues were most probably caused by the blog site rendering.
You might want to check engine.log (or server.log not really sure which
one was that) for aaa extension initialization logs. They should
appear at the beginning just after restarting engine.
Unfortunately, at the moment I do not have running keycloak setup (I
used to have a local VM) but I will try to find some time to set it up
again once I'm done with another work item that actually consumes
almost entire disk space for my 2 machines)
Please let me know if anything changes after applying these config
changes. It this works for you then I will request the blog post to be
updated.
Do you mind if I keep(re-post) this discussion back to users@ovirt in
case other might have similar issues with keycloak integration?

Yes, please try adding it. In my case I learned about this issue by debugging
the code because the real exception generated by incorrect regexp syntax was
hidden behind generic error message giving no clues about the true cause.

Mirror oVirt content
by adrianquintero＠gmail.com
Hello oVirt Community / infrastructure team,
we would like to get guidance on how to mirror the oVirt content publicly. We replicate content using our own networks so we'd only be pulling the content from the oVirt content server from one location in Chicago.
Please advise.
Thank you,

Not so long ago I managed to setup ovirt engine with keyloack (using
ldap as users provider). Hopefully, I would be able to help you with
it.
There is excellent blog post[1] available. You might also check
keycloak+ldap post [2], however, when I was working on the integration
I was not aware of if and did not test it.
The error you mentioned does not really indicate what exactly is wrong
but it might suggest that there is some sort of misconfiguration with
apache (you need to install and configure mod_auth_openidc as described
at [1]). At least that happened in my case.
In case you have already gone through it you could probably check
apache logs.
Under [1] there is a python script that can be used to check api calls,
please update username/password and test it against your environment.
Would it be possible post relevant piece of apache logs together with
engine.log ?

oVirt and KeyCloak intergration
by Anton Louw
Hi Everybody,
Has anybody gone the route of using KeyCloak to login to oVirt? KeyCloak has been configured and the neccesary configs have also been done on the engine. It redirects perfectly from the oVirt Web Login page to KeyCloak, but after logging into KeyCloak, I get redirected back to the oVirt Web Login. When trying to login again, I get the below error:
[cid:ea1b2738-7e36-4cdb-8650-191d6992853c]
server_error: Missing parameter: 'params'
I have checked all the logs, but nothing is telling me what exactly the issue is.
If anybody has any idea, please let me know.
Thanks

Migrate engine to another storage domain without losing engine settings?
by Simon Nylund
Have been trying to figure out a simple way of migrating our hosted-engine to another storage domain, while keeping the data on the same domain.
Is there any safe way of doing this? Fortunately I've only tested this in a dev environment, where I ended up with not being to able to restore the backup I did.
The only way I got it to work was to deploy a fresh engine attached to the new storage domain, and then import the data storage domain containing the vms.
The problem with that is that I lose all the settings I had in my hosted engine, and the hosts.
