Hosted Engine ansible runner artifacts cleanup
by Erez Zarum 11 Oct '21

11 Oct '21

Hey, I can't get the artifacts to cleanup, i have configured the ansible runner config.yml but it seems not to be running. Should i restart the ovirt-engine service? What is the best way to manually cleanup the artifacts (i can't get the correct ansible-runner command to clean it up) as it is starting to fill up disk space Thanks

Re: fresh hyperconverged Gluster setup failed in ovirt 4.4.8
by Ax Olmos 10 Oct '21

10 Oct '21

The problem is that the ‘glusterd_brick_t’ file context is missing from selinux-policy-targeted 3.14.3-80 on CentOS 8 Stream. It exists in the CentOS 8.4 version: rpm -qpl selinux-policy-targeted-3.14.3-67.el8_4.2.noarch.rpm | grep gluster /usr/share/selinux/targeted/default/active/modules/100/glusterd /usr/share/selinux/targeted/default/active/modules/100/glusterd/cil /usr/share/selinux/targeted/default/active/modules/100/glusterd/lang_ext /var/lib/selinux/targeted/active/modules/100/glusterd /var/lib/selinux/targeted/active/modules/100/glusterd/cil /var/lib/selinux/targeted/active/modules/100/glusterd/hll /var/lib/selinux/targeted/active/modules/100/glusterd/lang_ext Not on CentOS 8 Stream: rpm -qpl selinux-policy-targeted-3.14.3-80.el8.noarch.rpm | grep gluster You can remove the selinux checks from: /etc/ansible/roles/gluster.infra/roles/backend_setup/tasks/mount.yml but I’m not sure of the implications of that. This is a show stopper for oVirt and someone from oVirt needs to contact the CentOS 8 Stream maintainers and have them put the selinux context back, or come up with some other workaround.

Slow gluster replication
by David White 10 Oct '21

10 Oct '21

I can't remember if I've asked this already, or if someone else has brought this up. I have noticed that gluster replication in a hyperconverged environment is very slow. I just (successfully, this time) added a brick to volume that was originally built on a single-node Hyperconverged cluster. One of my volumes has over 600GB, but the network is 10Gbps, so replication really shouldn't take that long. It's been over two hours, and that volume has only replicated a little over 400GB. It feels like it's taking about 1GB every 30 seconds - 1 minute or so... Why would this replication be so slow? Sent with ProtonMail Secure Email.

Configuring LUNS for self-hosted engine install
by Virden, Gerald 08 Oct '21

08 Oct '21

Hi, I have a host with two 16TB LUNS that I want to deploy a self-hosted engine on. I have so far been unsuccessful; the install either fails or hangs and Oracle is saying it is due to storage. I can see both LUNS with multipath -ll. Does anyone know of step by step instructions on what to do to configure the LUNS so the engine will see them and set up the storage domain? Jerry

Re: fresh hyperconverged Gluster setup failed in ovirt 4.4.8
by Eddie Garcia 07 Oct '21

07 Oct '21

I have been having this issue as well with no solution working but I came across something interesting. In selinux-policy 3.14.3-77 they removed the glusterd selinux module. https://centos.pkgs.org/8-stream/centos-baseos-x86_64/selinux-policy-3.14.3… so that policy doesn exist anymore for ansible to apply. I plan on testing installing an older version into an ovirt node box to test which defaults as of 4.4.8 to selinux-policy version 3.14.3-79.el8. A clean install of CentOS 8 using latest iso has version 3.14.3-67.el8_4.2 and I can verify that manually setting policy with command 'semanage fcontext -a -t glusterd_brick_t "/gluster_bricks(/.*)?"' is completed successfully.

Import ISCSI target as data domain, cannot see old data
by joyzhao93＠gmail.com 06 Oct '21

06 Oct '21

Hi Team, Hope you are doing well. I had a standalone Ovirt Engine with 2 hosts, one 2TB ISCSI data domain (dell equallogic). Today the Ovirt Engine machine crashed so we have to bring up a new one, setup is good and when I try to import ISCSI data domain I can see volumes/Luns, but after import, Ovirt shows the volume is empty - 2TB free (so all old data on the ISCSI volume is not presenting). However when I login to the ISCSI target machine, it shows the old data (around 400GB) is in use. Seems like the new Ovirt Engine cannot detect the old ISCSI data domain disk content. Thank you, Sincerely, SYZhao

Deploying ovirt+gluster hyperconverged with standalone engine
by J W 06 Oct '21

06 Oct '21

I'm looking for the proper steps to deploy ovirt+gluster hyperconverged with standalone engine as the scenario doesn't seem to be covered here: https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Deploying_H… I have attempted to: 1) Deploy standalone engine 2) deploy 3 nodes and ran gluster deployment, stopping before the engine deploy 3) Added hosts to standalone engine I then attempt to add the gluster volumes to the standalone engine by specifying host1:/volume as glusterfs but the volume does not successfully add. Is there another perferred method for this type of deployment?

qemu-guest-agent not reporting IP address on boot?
by c.schreuders＠leedsbeckett.ac.uk 04 Oct '21

04 Oct '21

Hi folks, Kali Linux repos (based on Debian) no longer ship ovirt-guest-agent, and instead package qemu-guest-agent. However, since this upgrade VMs based on Kali no longer report their IP address to oVirt (and therefore timeout during provisioning). If I interact with the VM console, the VM does have an IP address, and the agent is running, yet oVirt reports N/A IP address. I've tried restarting the agent, but that does not help. If I load the console and use the VM it seems to increase the chances the IP address will eventually makes it's way to oVirt, although I can't seem to reproduce an update, or get it to provide the IP address on boot so that provisioning works reliably. Any suggestions would be really appreciated. Thank you. Cheers, Cliffe.

You have to reinstall the node that you isolated with the engine. So after taing the engine at its latest 4.3.x level and rebooting the 4.3 engine OS, you have to follow the steps described in 6.5: stop the ovirt-engine service, take a backup and copy the generated file outside of the env, scratch the engine and related node and reinstall it with 4.4 ovirt node and then on the host, now in 4.4, run the command hosted-engine --deploy --restore-from-file=backup.bck and so on...

Re: oVirt 4.3 DWH with Grafana

Thank you! I tried it, and I can import the json after replace the 4.4 with 4.3, but still have some errors like this: pq: column "count_threads_as_cores" does not exist Object status:400 statusText:"Bad Request" data:Object results:Object message:"pq: column "count_threads_as_cores" does not exist" message:"pq: column "count_threads_as_cores" does not exist" Many of the other reports worked fine, with only a few similar errors. Is this caused by version incompatibility? After all, 4.4 in the original document was replaced with 4.3 before the import.

Allowing Grafana to connect to oVirt DWH database (Data Warehouse) Login to the oVirt engine 4.3 and create a user "grafana" with password "grafana" that will get a read-only access to the ovirt_engine_history database and will be able to use public schema # su - postgres -c 'scl enable rh-postgresql10 bash' # psql -U postgres -c "CREATE ROLE grafana WITH LOGIN ENCRYPTED PASSWORD 'grafana';" -d ovirt_engine_history # psql -U postgres -c "GRANT CONNECT ON DATABASE ovirt_engine_history TO grafana;" # psql -U postgres -c "GRANT USAGE ON SCHEMA public TO grafana;" ovirt_engine_history Generate the rest of the permissions that will be granted to the newly created user and save them to a file: # psql -U postgres -c "SELECT 'GRANT SELECT ON ' || relname || ' TO grafana;' FROM pg_class JOIN pg_namespace ON pg_namespace.oid = pg_class.relnamespace WHERE nspname = 'public' AND relkind IN ('r', 'v');" --pset=tuples_only=on ovirt_engine_history > grant.sql Use the file you created in the previous step to grant permissions to the newly created user: # psql -U postgres -f grant.sql ovirt_engine_history Remove the file you used to grant permissions: # rm grant.sql Exit the postgres user shell by pressing Ctrl+d Add the following lines for the newly created user to /var/opt/rh/rh-postgresql10/lib/pgsql/data/pg_hba.conf preceding the line beginning local all all host ovirt_engine_history grafana 0.0.0.0/0 md5 host ovirt_engine_history grafana ::0/0 md5 Reload postgres service # systemctl reload rh-postgresql10-postgresql 2. Installing Grafana You can install Grafana directly on the oVirt Engine machine (this is how it's done in oVirt 4.4) or on a separate machine. Following steps shows how you can install Grafana on a Oracle Linux 7 server. Note: Oracle provides Grafana in the OLCNE yum repository - you only need to install the repository definition package to pickup Grafana and it's dependencies. # yum install oraclelinux-release-el7 # yum install oracle-olcne-release-el7 # yum-config-manager --enable ol7_optional_latest ol7_olcne11 # yum install grafana # systemctl enable --now grafana-server 3. Adding oVirt DWH database as Data Source in Grafana Login to Grafana (default port 3000) and navigate to Configuration -> DataSources and click on Add Data Source button. Select PostgreSQL source and use the following settings (adjust the Host IP address to match your oVirt Engine IP but do not change the Name): Name: oVirt DWH Host: your-engine-ip-address:5432 user: grafana pass: grafana SSL mode: disable 4. Importing Dashboards from oVirt 4.4 Download Grafana Dashboards from oVirt 4.4 repository: https://github.com/oVirt/ovirt-dwh/tree/master/packaging/conf/grafana-dashb… You can now import them in Grafana by navigating to Create -> Import and clicking on Upload .json file or by simply pasting JSON content. I've tested this on my OLVM/oVirt 4.3 and works perfectly well. Have fun!

I am looking into guidelines, how to, for setting up Grafana using DataWarehouse as data source. Did anyone already did this, and would be willing to share the steps? AFAIU this is definitely not tested/recommended/supported, but the current (4.4) dashboards use only 4.3 dwh compatibility views. So in theory, 4.4 grafana setup can work against your 4.3 engine/dwh without problems. So you can try something like: 1. Install el8 on some machine 2. Install ovirt-release (4.4!) 3. Install ovirt-engine-dwh-grafana-integration-setup. I *think*, didn't try, that it would carry with it all the dependencies it needs. 4. Run engine-setup. When prompted, only accept "Configure grafana?", and reply "No" to everything else 5. Follow the other prompts as applicable This should be enough. Not sure about the commands to add SSO on the engine machine. Perhaps better verify this first against a test engine (can be on another el7/ovirt4.3 VM with no hosts). But, repeating: this isn't recommended. Did you consider upgrading only your engine, and keep your hosts 4.3 until you can upgrade them later?

Live domain migration breaks Windows (UEFI) vitrual machine
by Patrick Lomakin 02 Oct '21

02 Oct '21

Greetings! I've already mentioned the problem of live disk migration between different storage domains, but yesterday I found the same problem in a new oVirt installation. My actions after deploying oVirt are: 1) Created a storage domain (iSCSI and Gluster); 2) Created a virtual machine with Windows 10 (UEFI); 3) Placed the virtual machine on the Gluster domain; 4) Started the virtual machine and started moving the disk from the Gluster storage domain to iSCSI. The disk move process was successful and error free and the virtual machine worked. However, after a reboot, the machine no longer started. The boot goes into recovery mode. All attempts to restore the machine to work were unsuccessful. I want to note that this does not happen if the machine was turned off during the disk move. In this case, it starts up without any problems. The type of domain from or to which the disk is migrated does not important. In case of live migration the Windows (UEFI) VM crashes in any case.

Upgrading from 4.3 to 4.4.8
by jasonmicron＠gmail.com 02 Oct '21

02 Oct '21

You guys scare me. Seriously. I'm trying to update from oVirt 4.3 to 4.4 using a self-hosted engine. All VMs on the host are migrated off, other than the hosted engine, from the first host I intend to update to EL 8.4, per the documentation. I installed the RPM from here: https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm I'm configuring the Engine following the upgrade document located here: https://www.ovirt.org/documentation/upgrade_guide/index.html#SHE_Upgrading_… Step 6.4, after installing the oVirt 4.4 RPM on the engine: engine-upgrade-check - I get this response: [root@labmanager yum.repos.d]# engine-upgrade-check VERB: queue package ovirt-engine-setup for update VERB: Downloading: ovirt-4.3-epel/x86_64/metalink (0%) VERB: Downloading: ovirt-4.3-epel/x86_64/metalink 10 k(100%) FAIL: Cannot queue package ovirt-engine-setup: Cannot find a valid baseurl for repo: ovirt-4.4/7 OK: Performing yum transaction rollback Error: Cannot find a valid baseurl for repo: ovirt-4.4/7 Doing a 'yum update' to just validate yum is working correctly, after installing the 44 RPM, I get this: Cannot find a valid baseurl for repo: ovirt-4.4/7 Any advice? Is the repo just not valid at the moment? Did someone forget to run a 'createrepo' after updating the YUM/DNF repo?
