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.

Hi, Can't add new host to ovirt engine, because the following error: 2019-06-12 12:23:09,664 p=4134 u=engine | TASK [ovirt-host-deploy-facts : Set facts] ************************************* 2019-06-12 12:23:09,684 p=4134 u=engine | ok: [10.35.1.17] => { "ansible_facts": { "ansible_python_interpreter": "/usr/bin/python2", "host_deploy_vdsm_version": "4.40.0" }, "changed": false } 2019-06-12 12:23:09,697 p=4134 u=engine | TASK [ovirt-provider-ovn-driver : Install ovs] ********************************* 2019-06-12 12:23:09,726 p=4134 u=engine | fatal: [10.35.1.17]: FAILED! => {} MSG: The conditional check 'cluster_switch == "ovs" or (ovn_central is defined and ovn_central | ipaddr and ovn_engine_cluster_version is version_compare('4.2', '>='))' failed.

by Jacob M. Nielsen 03 May '23

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

Ovirt 4.5.0 Support (End of Life Date)
by masood.ahmed＠digital.mod.uk 21 Apr '23

21 Apr '23

Hi, I am working on a project and we would like to utilise (oVirt 4.5.) as the platform for our enterprise infrastructure. We have arrived at this juncture because of a range of considerations related to hardware and software availability and compatibility. My question is if there is on-going vendor \ professional support for oVirt moving forward, as one of my colleagues spoke with Red Hat, who stated they are going to end their support for the product. we will not gain security accreditation for our project unless we have professional support available, community support only is not sufficient, Any ideas of firms available for a support contract for oVirt 4.5.0? thanks

apparently it seems to break the upgrade of my engine to a newer version. any way to avoid this or where to fix it ? it appears, when the local external engine is deployed and tries to install the "new" host.

Support for ARM 64
by shubha.kulkarni＠oracle.com 13 Apr '23

Hello, I am trying to understand support for ARM architecture in OVirt. I came across this oVirt doc https://www.ovirt.org/documentation/installing_ovirt_as_a_standalone_manage…. It mentions ‘The oVirt project also provides packages for the 64-bit ARM architecture (ARM 64) but only as a Technology Preview.’ So I am wondering where I can find the packages and document/steps to install oVirt on aarh64 architecture. Also, I looked at upstream oVirt engine source code and saw no reference to ARM CPU types. So I am wondering if the engine running on x86 system supports adding ARM 64 host. Thanks, Shubha
