Unable to sync network settings on new Ovirt installation
by Patrick Lomakin 24 Dec '22

24 Dec '22

Hi guys! I encountered a network error that I had not encountered before in a previous installation. I need to set up another network in addition to the ovirtmgmt network to migrate virtual machines, because when migrating a large number of machines, the ovirtmgmt network is loaded to its maximum. And as you know and documentation - all or none of the networks must or must not have a QoS rule. After creating the migration network, I added this network QoS rule and also added QoS to the ovirtmgmt network. But I get this kind of error - Error while executing action HostSetupNetworks: Unknown exception. In the logs I noticed the following: {'reason': "(2, 'Error: TC classifier not found.\nWe have an error talking to the kernel\\n', ['/sbin/tc', 'filter', 'replace', 'dev', 'bond0', 'protocol', 'all', 'parent', '1389:', 'pref', '200', 'basic', 'match', 'meta(vlan eq 200)', 'flowid', '1389:c8')"} Who can tell me where to put my energy to find a solution?) Good luck everyone!

Hi folks! I've have a oVirt 4.4.x installation running for 453 days now without issue. Now that I had some time over the holiday, I thought it would be good to upgrade it to the latest 4.5.x, however im getting stumped on an upgrade step which upgrades the engine setup: https://pastebin.com/mxf6E1R9 A small snippet of the paste-bin here: [root@cloud ovirt-engine]# dnf update ovirt\*setup\* Last metadata expiration check: 0:22:46 ago on Fri 23 Dec 2022 05:55:39 PM CST.

FC - Storage domain - space question + direct LUN (FC) SCSI passthrough a good idea ?
by morgan cox 22 Dec '22

22 Dec '22

Hi. Couple of questions regarding Fibre Channel Storage .. sing fibre channel storage domains - I know when you create storage domains you get 2 files on them 'OVF_STORE' which are less than 1 GB. I am using PREALLOCATED (RAW?) disks - if I were add a (preallocated) disk that fills the entire space would any issues occur ? e.g the 2 OVF_STORE files are preallocated so I assume they will not grow (or need another one adding in future ?) - I have noticed 'Critical Space Action Blocker:' size - what happens if my disk covers the entire free space in a stoage domain (when using preallocated disks) Also as a 2nd question : Rather than using a storage domain if I were to create disks using Direct LUN (Fibrechannel LUN) is it a bad idea to enable SCSI-PassThrough ? I ask as the simple FIO benchmarks I did showed improved performance. Thanks

what happens at vdsm host certificate expiration
by Vinz Vinz 20 Dec '22

20 Dec '22

Hi Team, we are using a custom certificate on the engine apache GUI /etc/pki/ovirt-engine/certs/apache.cer (following https://myhomelab.gr/linux/2020/01/20/replacing_ovirt_ssl.html) and it works fine. The certificate is valid for a very long period. It seems the vdsm certificate (/etc/pki/vdsm/certs/vdsmcert.pem), on hosts side, has been renewed automatically at that time, but for only one year. Now we wonder, what will happen when the vdsm certificate will expire? hosts will stop to be in the cluster? if yes what should we do to avoid that? is there a possibility to also apply our custom cert as vdsm cert? This is for ovirt 4.4 running on rhel8 thx a lot in advance

Hosted-engine update error
by Jason Beard 20 Dec '22

20 Dec '22

Greetings! I was updating from ovirt 4.5.3 to ovirt 4.5.4 and my hosted engine has some package errors but the update seems to complete. The errors still exist with dnf. I feel like this is something that needs to be resolved but not sure. When I query the rpmdb I do see ovirt-*-4.5.4.x packages are installed. When I ran the engine-setup it completed with no errors.
