Hi, about two years ago, I used OST to setup a oVirt test/dev environment. Now I tried again, following https://github.com/oVirt/ovirt-system-tests/blob/master/README.md but it fails because https://templates.ovirt.org/yum/ is unavailable. Or isn't it meant to be available for public access any more? Regards, Stephan

[VDSM] Started getting virNetTLSContextCheckCertTimes:154 : The server certificate /etc/pki/vdsm/certs/vdsmcert.pem has expired
by Edward Haas 11 Jan '24

Hi, I have a VM which acts as an oVirt host with VDSM installed. I use it for testing without connecting it to Engine. Recently VDSM fails to come up and I see this error: Sep 26 17:58:18 localhost libvirtd: 2018-09-26 14:58:18.978+0000: 12176: error : virNetTLSContextCheckCertTimes:154 : The server certificate /etc/pki/vdsm/certs/vdsmcert.pem has expired Any hint on how to generate or fetch a new certificate without the help of Engine? Thanks, Edy.

Ovirt Admin VM Portal url Not Loading on the Browser After Successful HE Deployment.
by igwevic70＠gmail.com 18 May '23

18 May '23

Hi there, I need some help here, please. I am new to ovirt and I am trying to setup ovirt 4.5.4 a test env. I have successfully deployed HE using "hosted-engine --deploy" after days of encountering a lot of issues, but the current issue now is that I can't access the VM Portal ie WebUI, where I can create VM from the Admin portal. One thing I noticed is that during the deployment process, it supplies a temporary url link like "https://ovirt-node-03.projectplus.com:6900/ovirt-engine" to access the web but when the deployment is done, it kills the this url and it becomes unavailable with no web access again Can someone please please, help me to understand what's going on. I have done this deployment nearly 10x but still getting the same thing, I can just have webui access to the Admin Portal. Thanks in advance for your help. Vik.

Invalid value '-1' for 'cpu.max': Invalid argument
by lejeczek 15 May '23

15 May '23

Hi guys. with latest stable ovirt node, hosted engine setup fails at, I guess late stage: ... [ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Notify the user about a failure] [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Host is not up, please check logs, perhaps also on the engine machine"} as setup sits & waits for a while, before it errors out, I see this in logs: ... 12687 still running (84875) Invalid value '-1' for 'cpu.max': Invalid argument 12687 still running (84870) 12687 still running (84865) 12687 still running (84860) Invalid value '-1' for 'cpu.max': Invalid argument ... and logs continue after engine setup has finished. I've browsed around but resolutions I found did not help, also I suspect it might be a bug thus any comments on how to fix it, are very much appreciated - btw, why BZs reports should go? many thanks, L.

Console Disconnect Action
by Shubha Kulkarni 12 May '23

12 May '23

Hello, I am experimenting with the feature ‘console disconnect action’ . It provides four actions on disconnect.  Lock screen - This is the default option. For all Linux machines and for Windows desktops this locks the currently active user session. For Windows servers, this locks the desktop and the currently active user.  Logout user - For all Linux machines and Windows desktops, this logs out the currently active user session. For Windows servers, the desktop and the currently active user are logged out.  Shutdown virtual machine - Initiates a graceful virtual machine shutdown.  Reboot virtual machine - Initiates a graceful virtual machine reboot. In my testing, the shutdown and reboot options worked. However, lock screen and logout user option did not work for me. I looked around and found out that qemu-guest agent has no command to log off a user. I see ovirt-guest-agent has some code to logout user as described below - https://github.com/oVirt/ovirt-guest-agent/blob/master/ovirt-guest-agent/Lo… However, it turns out that the ovirt-guest-agent is not supported anymore. So I am wondering how the ‘lock screen’ and ‘logout user’ is implemented and whether it is still supported/supposed to work? Thanks, Shubha

this is probably a bug: cannot import name 'Callable' from 'collection

Hi guys Just to let you know that both stable & testing fail to setup hosted engine very early in the process, in Centos 9 [ ERROR ] b'[WARNING]: Skipping plugin (/usr/share/ovirt-hosted-engine-\n' [ ERROR ] b'setup/he_ansible/callback_plugins/2_ovirt_logger.py), cannot load: cannot\n' [ ERROR ] b"import name 'Callable' from 'collections'\n" [ ERROR ] b'(/usr/lib64/python3.11/collections/__init__.py)\n' [ ERROR ] b"ERROR!

Hi List I have trouble to find information regarding how to performance tune my IO on my VM. We see bad performance max 30 MB/s from the VM to the storage (Posix mounted file system) We have tested the filesystems locally from the Ovirt host , and we can easy get +500MB/s Found a parameter <io> <threads>2</threads> </io> I can't find recommended configuration regarding this parameter. My question is which value is should use for this , when having 60 high performance disks mapped to my VM Somebody any answers tnx
