ovirt-engine - developer mode installation
by yongshengmaa＠126.com
Hello ,
I'm doing a developer mode installation for ovirt-engine. I'd like to install it based on CentOS 8 Stream, but no matched version of postgresql packages are provided. Which CentOS version should I start this work?
Sincerely,
Yongsheng

Hosted deployment difficulties, am I missing anything?
by Xavier Lauzon
Hi everyone,
Last week I had a server go down, which was the only node in my deployment handling the hosted engine (ironically, this happened right when we were planning to move the he to HA). As a result, we have been trying to redeploy the engine but have had no success.
We have tried installing on every ovirt node ng stable version from 4.4.10-4.5.4.el8 and .el9. Unfortunately, each time we try to deploy the engine from scratch, we receive either of two errors depending on the version. Some versions fail to create the default network, which can be manually fixed but leads to the following error. The deployment goes until the "Waiting for host to be up" stage; however, it fails without any information as to why. I've sifted through virtually all the logs but can't find the root cause. I am aware of an ongoing issue in the ansible collection (https://github.com/oVirt/ovirt-ansible-collection/issues/695); however, even the fix outlined there does not seem to solve this issue. Additionally, I have headed the recent advice from Sandro to switch to the nightly version. Unfortunately, this has also not been working on either ovirt node or CentOS 9/8, and today has resulted in the following error:
[ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "cmd": ["virsh", "net-dumpxml", "default"], "delta": "0:00:00.077767", "end": "2023-04-17 17:00:05.980049", "msg": "non-zero return code", "rc": 1, "start": "2023-04-17 17:00:05.902282", "stderr": "error: failed to get network 'default'\nerror: Network not found: no network with matching name 'default'", "stderr_lines": ["error: failed to get network 'default'", "error: Network not found: no network with matching name 'default'"], "stdout": "", "stdout_lines": []}
[ ERROR ] Failed to execute stage 'Closing up': Failed getting local_vm_dir
Please let me know what additional information needs to be provided; I am more than happy to do so.
Is there something I'm missing here? Is there a version that is confirmed to be working at the moment?
I am grateful for anyone who takes the time to look into my issue,

/tmp/lvm.log keeps growing in Host
by kanehisa＠ktcsp.net
I don't understand why lvm.log is placed in /tmp directory without rotation.
I noticed this fact when I got the following event notification every 2 hours.
EventID ：24
Message ：Critical, Low disk space. Host ovirt01 has less than 500 MB of free space left on: /tmp. Low disk space might cause an issue upgrading this host.
As a workaround, I added a log rotation setting to /tmp/lvm.log, but is this the correct way?
I should have understood the contents of the Python program below before asking the question,
but please forgive me because I am not very knowledgeable about Python.
# cat /usr/lib/python3.6/site-packages/blivet/devicelibs/lvm.py | grep lvm.log
config_string += "log {level=7 file=/tmp/lvm.log syslog=0}"
Thanks in advance!!

4.5.2 hosted-engine deployment failed
by j9678＠hotmail.com
The engine deployment failed with message "Host is not up, please check logs, perhaps also on the engine machine" after "Wait for the host to be up".
I couldn't find any particular error in setup log, it just failed without pointing out any reason. I've tried on ovirt node (el9 and el8) and RHEL 8.7.

Re: unable to connect to the graphic server with VNC graphics protocol
by Devin A. Bougie
Hi Murilo,
Yes, when trying with noVNC we get:
Something went wrong, connection is closed
This is getting pretty urgent for us, so any help connecting to the console of VMs running on EL9 hosts would be greatly appreciated.
Thanks for following up,
Devin
