Safely disable firewalld [Ovirt 4.3]
by francesco＠shellrent.com 22 Apr '20

22 Apr '20

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

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?

However, now I recall I made some changes compared to blog post example: 1) /etc/ovirt-engine/extensions.d/openid-http-mapping.properties I added escaping in regexp for '\' ... config.mapAuthRecord.regex.pattern = ^(?<user>.*?)((\\\\(?<at>@)(?<suffix>.*?)@.*)|(?<realm>@.*))$<file://(%3f%3cat%3e@)(%3f%3csuffix%3e.*%3f)@.*)(%3f%3crealm%3e@.*))$)$> ... 2) /etc/httpd/ovirt-openidc.conf Escaping for '"' in error document snippet ... <LocationMatch ^/ovirt-engine/sso/(interactive-login- negotiate|oauth/token-http-auth)|^/ovirt-engine/callback> <If "req('Authorization') !~ /^(Bearer|Basic)/i"> Require valid-user AuthType openid-connect ErrorDocument 401 "<html><meta http-equiv=\"refresh\" content=\"0; url=/ovirt-engine/sso/login-unauthorized\"/><body><a href=\"/ovirt-engine/sso/login-unauthorized\">Here</a></body></html>" </If> </LocationMatch> ... 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? A.

Mirror oVirt content
by adrianquintero＠gmail.com 21 Apr '20

21 Apr '20

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, Adrian

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 21 Apr '20

21 Apr '20

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 Anton Louw Cloud Engineer: Storage and Virtualization ______________________________________ D: 087 805 1572 | M: N/A A: Rutherford Estate, 1 Scott Street, Waverley, Johannesburg anton.louw(a)voxtelecom.co.za www.vox.co.za

Migrate engine to another storage domain without losing engine settings?
by Simon Nylund 21 Apr '20

21 Apr '20

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.

spice options hook
by ozmen62＠hotmail.com 21 Apr '20

21 Apr '20

Hi, We're using oVirt 4.3 and want to use spice streaming to better user experience, for example youtube etc. I've tried to use before_vm_start script, but lots of problems came out. 1 - on default environmet, hook script returns of no such file or directory, because python3 does not exist on the system if i install python3, vdsm stops working if change interpreter in the script, vdms retuns rc=0 error code hook=114 and it does not appear on the vm custom properties So, could you help me to run this hook properly we've tested https://github.com/oVirt/vdsm/tree/master/vdsm_hooks/spiceoptions Master and 4.3 branch returns same error code and nothing appeared on the "custom properties" is there anyone who is use it successfully 2 - for this experince is GPU neccessery (not vGPU) , our server has standard 8mb onboard gpu thanks

Correct workflow for modifying engine vm.conf file
by Gianluca Cecchi 21 Apr '20

21 Apr '20

Hello, I would like to know a way to interact and modify in a "supported"/working way the vm.conf file on shared storage that contains details for the engine vm and I think is the base to dynamically generate the /var/run/ovirt-hosted-engine-ha/vm.conf In the past it was possible to temporarily modify the file under /var/run (or copy to another location) and start engine with it, but now it seems it doesn't work and that the file is continuously updated/refreshed Eg on engine storage domain on a lab with oVirt 4.4. beta4 I have the tar file [root@novirt2 ~]# tar tvf /rhev/data-center/mnt/glusterSD/novirt2st.storage.local\:_engine/7c9397f5-859b-4fba-bcc5-4ecbd454a189/images/530490b0-935e-46a8-84f6-6cd6618c6f0d/2e0f414c-2589-4545-a0a4-3bfed24ef3fc -rw-r--r-- root/root 181 2020-04-19 15:04 broker.conf -rw-r--r-- root/root 2777 2020-04-19 15:04 fhanswers.conf -rw-r--r-- root/root 1076 2020-04-19 15:04 hosted-engine.conf -rw-r--r-- root/root 6 2020-04-19 15:04 version -rw-r--r-- root/root 1359 2020-04-19 15:04 vm.conf [root@novirt2 ~]# And its vm.conf has: cpuType=Cascadelake-Server,+md-clear,+mds-no,-hle,-rtm,+tsx-ctrl,+arch-capabilities I would like to modify it and remove the "+tsx-ctrl" flag. Is there anything in the database that generates modification in the file on shared storage and then on the directory under /var/run? Or how is all the workflow managed to generate at the end the xml file to use to start the engine vm? What is that initially determines how to populate the cpuType in vm.conf at all? Thanks, Gianluca
