managing local users in 4.2 ?
by Matthias Leopold 06 May '18

06 May '18

Hi, i tried to create a local user in oVirt 4.2 with "ovirt-aaa-jdbc-tool user add" (like i did in oVirt 4.1.9). the command worked ok, but the created user wasn't visible in the web gui. i then used the "add" button in admin portal to add the already existing user and after that the user was visible. i didn't have to do that in 4.1.9, the "add" button was already there the, but i didn't know what to do with it. how did managing local users change in 4.2? thx matthias

oVirt messages from engine to vdsm
by Anastasiya Ruzhanskaya 06 May '18

06 May '18

Hello everyone! Currently I want to determine what information is included in messages passing from oVirt engine to VDSM on ovirt-node. I made up a really simple configuration with one VM representing engine, another - node, a managed to successfully launch a single VM on this node. However, I have chosen to configure everything automatically. Currently traffic is encrypted with default certificates. So, there are three options for me and no one of them really works. 1) Find the format of messages ( what the fields are, session id for example) in docs, but I didn't manage to find it; 2) Use wireshark to decrypt the traffic and the apply maybe a json -dissector to the decrypted data. I have tried many solutions ( thanks god I have rsa private and public keys but there is another session key which is generated every time engine starts to communicate with vdsm, which I cannot get with the help of sslkeylog file or ld_preload technology. Maybe someone knows the exact methodology how to do this correctly? 3) Turn off ssl in oVirt. It is simple to do that for vdsm, but for engine, according to answers on oVirt site, I should do 2 requests to the database. I was really surprised that psql was not installed by oVirt on my system. How did it then created a default database? ( I have chosen to create all locally and with default configurations). I mean these two commands : https://www.ovirt.org/develop/developer-guide/vdsm/connecting-development-v… . I have a following error there : psql: FATAL: Peer authentication failed for user "engine" Could you please guide my what method is the best and how should I correct my faults there?

Can't add newly reinstalled ovirt node
by Jakov Sosic 04 May '18

04 May '18

Hi, after installing 4.2.1.1 oVirt node, and adding it in hosted oVirt engine I get the following error: Ansible host-deploy playbook execution has started on host vhost01. Ansible host-deploy playbook execution has successfully finished on host vhost01. Status of host vhost01 was set to NonOperational. Host vhost01 does not comply with the cluster Lenovo networks, the following networks are missing on host: 'VLAN10' Host vhost01 installation failed. Failed to configure management network on the host. One more interesting thing: Compute => Hosts => vhost02 => Network interfaces is empty... there are no recognized interfaces on this host. Any idea?

Recovering oVirt-Engine with a backup before upgrading to 4.2

--_000_41e0a4df7d7b4b04824f154982fe953fepsaero_ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Hi All, I'm still facing issues with my HE engine. Here are the steps that I took t= o end up in this situation: - Update Engine from 4.1.7 to 4.1.9 o That worked as expected - Automatic Backup of Engine DB in the night - Upgraded Engine from 4.1.9 to 4.2.1 o That worked fine - Noticed Issues with the HA support for HE o Cause was not having the latest ovirt-ha agent/broker version on hosts - After updating the first host with the latest packages for the Ag= ent/Broker engine was started twice o As a result the Engine VM Disk was corrupted and there is no Backup of = the Disk o There is also no Backup of the Engine DB with version 4.2 - VM disk was repaired with fsck.ext4, but DB is corrupt o Can't restore the Engine DB because the Backup DB from Engine V 4.1 - Rolled back all changes on Engine VM to 4.1.9 and imported Backup o Checked for HA VMs to set as disabled and started the Engine - Login is fine but the Engine is having trouble picking up and inf= ormation from the Hosts o No information on running VMs or hosts status - Final Situation o 2 Hosts have VMs still running and I can't stop those o I still have the image of my corrupted Engine VM (v4.2) Since there were no major changes after upgrading from 4.1 to 4.2, would it= be possible to manually restore the 4.1 DB to the 4.2 Engine VM to this up= and running again or are there modifications made to the DB on upgrading t= hat are relevant for this ? All my work on rolling back to 4.1.9 with the D= B restore failed as the Engine is not capable of picking up information fro= m the hosts. Lessons learned is to always make a copy/snapshot of the engin= e VM disk before upgrading anything. What are my options on getting back to= a working environment ? Any help or hint is greatly appreciated.
