[ovirt-users] Safely disable firewalld [Ovirt 4.3]
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?

Last time I had to forcibly remove a node because it was impossible to do so otherwise, it had never ever had anything to do with gluster, so I STRONGLY dispute your claim that fixing an issue (that was not stated) will fix anything.

[ovirt-users] Re: How to force removal of old host from Engine
Not a good approach. It's important to know if the node was also a gluster peer in the storage pool - if yes, it needs to be replaced with 'replace-brick' or 'reset-brick' (depending if you use the old hostname or not). Once the storage node is replaced - oVirt will allow you to remove it.

[ovirt-users] How to force removal of old host from Engine
Hi, I seem to have got a stale host in my engine that I can't remove. I recently reinstalled oVirt Node on this host and while trying to refresh the host in the engine, have got it in some state where I can't do anything. The host is listed as Status=Unassigned. Under the Management pull down I only have Restart and Stop options, both of which error if selected. The Remove button is not available. How do I force a removal of this host from the view so I can reload it?

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-users] oVirt and KeyCloak intergration
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.

Hm, could you try instead:
spiceoptions={'streaming':{'mode':'all'}}

I can tell if streaming is enable if you provide qemu cmd line

Looking at the hook you posted earlier: https://github.com/oVirt/vdsm/blob/master/vdsm_hooks/spiceoptions/before_vm_start.py It needs user to provide the options and for this feature to work streaming=filter or streaming=all must be giving to spice server to enable streaming. > do i need to change something on host or engine I need to > solve youtube or other video problems For mjpeg encoding, you don't need to change anything. For x264/vp8 with GStreamer, spice must be built with GStreamer option enabled.
