Re: About the vm memory limit

transparent huge pages are not used on vm and physical host. But, can I enable hugepage memory on virtual machines but not on a physical machine? For database running on vm, and it needs to config hugepage.

If you have 256G per CPU, it's best to stay into that range. Also, consider disabling transparent huge pages on the host & VM. Since 4.4 Regular Huge Pages (do not confuse them with THP) can be used on the Hypervisors, while on 4.3 there were some issues but I can't provode any details.

As long as there is memory on the physical machine, the more virtual machines the better? In our usage scenario, there are many virtual machines with databases, and their memory varies greatly. For some virtual machines, 4G memory is enough, while for some virtual machines, 64GB memory is needed. I want to know what is the best use of memory for a virtual machine, since the virtual machine is just a QEMU emulation process on a physical machine, and I worry that it is not using as much memory as a physical machine.

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?

Reinstall without dataloss
by hans＠jiflin.nl 02 Oct '21

02 Oct '21

Hi all, I am new here, been searching the mailing list on a regular base when I encountered problems and till now I always was able to keep the system up & running. As said... till now... I have oVirt at home, and I have about 7 vm's running on it. Lately I have had some troubles with my electricity, which results in a complete power outage on a irregular base. Yesterday I had a power outage which left the system unbootable with the following errors: error: ../../grub-core/loader/i386/pc/linux.c:170:invalid magic number. error: ../../grub-core/loader/i386/pc/linux.c:1418:you need to load the kernel first. Press any key to continue Normally this can be solved following https://access.redhat.com/solutions/5829141, but his time also the files in /boot had a size of 0 bytes. So basically i did not have a working kernel on the system anymore. https://www.thegeekdiary.com/centos-rhel-7-how-to-install-kernel-from-rescu… does work for CentOS 8 also, but the ovirt 4.8 iso does not have the same directory structure. Using CentOS 8 installs a kernel, but not a bootable system. Is there a way i can start the installer in troubleshooting mode so I can reinstall just the kernel on the system?

about the expiration time of the oVirt certs
by Tommy Sway 01 Oct '21

01 Oct '21

As you know, there are many kinds of certificates in Ovirt, used for communication, authentication and so on. However, in practice, there is a security risk related to the above certificates. That is, you need to generate a new certificate after the certificate expires. Otherwise, a problem will occur. In addition, different certificates expire at different times, which brings a lot of management trouble to users. Especially in the production system, a huge virtualization cluster may run thousands of VMS. If a cluster certificate has a problem, the impact is very serious. So I felt there was an urgent need for a technical tool that could help users quickly locate certificates, identify their expiration dates, and rebuild them. Even if there is no tool, there should be a way to solve the problems caused by partial certificate expiration. I think it should include the following points: First, how to list the certificate in detail Second, how to check the certificate expiration time Third, how to rebuild the certificate Does anyone else have this kind of confusion? What's a good solution? Thanks.

Using third-party certificate: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
by nicolas＠devels.es 01 Oct '21

01 Oct '21

Hi, I'm making a bare metal oVirt installation, version 4.4.8. 'ovirt-engine' command ends well, however, we're using a third-party certificate (from LetsEncrypt) both for the apache server and the ovirt-websocket-proxy. So we changed configuration files regarding httpd and ovirt-websocket-proxy. Once changed the configurations, if I try to log in to the oVirt engine, I get a "PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target" error. In prior versions we used to add the chain to the /etc/pki/ovirt-engine/.truststore file, however, simply listing the current certificates seems not to be working on 4.4.8. # LANG=C keytool -list -keystore /etc/pki/ovirt-engine/.truststore -alias intermedia_le -storepass mypass keytool error: java.io.IOException: Invalid keystore format Is there something I'm missing here? Thank

Hello, good evening, I want to consult the following case, we have two ovirt 3.6 servers with hosted-engine, yesterday some multipath servers were presented and two machines were blocked, which was not possible to start, checking we found that the ssl of the nodes They are expired and we change them only in the nodes. We could start the hosted-engine but the two nodes are not responsive comes out in vdsm daemon vdsm [43067]: vdsm ProtocolDetector.SSLHandshakeDispatcher ERROR Error during handshake: unexpected eof I appreciate any ideas or suggestions to be able to recover normal operation.

Intermittent failure to upload ISOs
by aclysma＠gmail.com 30 Sep '21

This may be the same issue as described here: https://lists.ovirt.org/archives/list/users@ovirt.org/thread/CJISJIDQKSINIJ… https://bugzilla.redhat.com/show_bug.cgi?id=1977276 I am on 4.4.8.6-1.el8, installed a couple days ago from the ovirt node ISO. In particular, I noticed if I SSH into the hosted engine and tail -f /var/log/ovirt-imageio/daemon.log, in the failure case I get something like: 2021-09-30 08:15:52,330 INFO (Thread-8) [http] OPEN connection=8 client=::ffff:192.168.1.53 2021-09-30 08:16:23,315 INFO (Thread-8) [http] CLOSE connection=8 client=::ffff:192.168.1.53 [connection 1 ops, 30.984947 s] [dispatch 1 ops, 0.000097 s] No activity in tail -f /var/log/ovirt-imageio/daemon.log on the host (I only have one host) in the failure case, just the engine. In the success case, there is activity in both logs. It is very intermittent. Sometimes uploads work most of the time (maybe 4 out of 5), and I've had other times that uploads do not work at all (0 out of 5). I think when it's behaving particularly badly, restarting the engine (hosted-engine --vm-shutdown, then hosted-engine --vm-start) helps, but I haven't figured out a reliable pattern. (I am logged in as admin.) I've tried several browsers, closing/reopening the browser, etc. Hoping this info will help in tracking it down.

oVirt/Hyperconverged issue
by topoigerm＠gmail.com 30 Sep '21

30 Sep '21

I have 4 servers of identical hardware. The documentation says "you need 3", not "you need 3 or more"; is it possible to run hyperconverged with 4 servers. Currently all the 4 nodes server has been crashed n after the 4th node try joining the hyperconverged 3nodes cluster. Kindly advise. FYI currently i'm trying to reinstall back all the OS back due mentioned incident happen. BR Faizal
