Migrating from a self hosted engine to standalone
by redhat＠intheoutback.com
Hi, I am in the process of moving our oVirt environment from a self hosted engine to a standalone engine on it's own HW. I have Googled and found a procedure for standalone > self hosted, but not the other way around.
My current situation is that I have 5 locations running oVirt 4.3 with 3 to 4 hypervisors and iSCSI storage backend, with a self hosted engine. All these locations are operational and short a downtime is acceptable if a must, losing a VM is NOT good.
I also have 1 oVirt environment 4.3 with 2 hypervisors and iSCSI backend that is my QA/Test.
All my networks are on internal networks with no outside world connections.
Most importantly, we are also looking at upgrading from 4.3 to 4.4
I have not found any straightforward way to migrate from self hosted to standalone.
My current plan is to do the following.
1) Create a new 4.4 standalone engine
2) Remove one hypervisor from the 4.3 cluster
3) Kickstart the hypervisor to RHEL 8.8 and configure ready for oVirt 4.4
4) Add the new host to the standalone engine.
5) Shutdown and export a number of VMs in the oVirt 4.3 and import them in to the new oVirt 4.4.
6) Repeat steps 2 > 5 until the everything is moved over.
Just wanting to get your expert opinions on this method or is there a much quicker easier method that will not risk the chances of losing the cluster/VMs or an extended outage.
Since we need to upgrade anyway from 4.3 to 4.4 I thought this the better method that upgrading the operational clusters.
Thanks

by Sachendra Shukla
Hi Team,
The oVirt Engine certificate is scheduled to expire on February 1, 2024.
Consequently, we need to initiate the certificate upgrade process. Could
you please share the steps and process for the certificate upgrade? I have
attached a snapshot below for your reference.

oVirt 4.5.5 - Prb with qemu-kvm after upgrade
by Christophe GRENIER
Hello
I have a standalone oVirt Manager 4.5.5-1.el8 and two small clusters.
After upgrading ovir01001 in the "PreProd" cluster from AlmaLinux 8.8 to
8.9, the host was successfully activated but failed to take any VM.
centos-release-ceph-pacific.noarch 1.0-2.el8 @cs8-extras
centos-release-gluster10.noarch 1.0-1.el8s @cs8-extras-common
centos-release-nfv-common.noarch 1-3.el8 @cs8-extras
centos-release-nfv-openvswitch.noarch 1-3.el8 @cs8-extras
centos-release-opstools.noarch 1-12.el8 @cs8-extras
centos-release-ovirt45.noarch 8.9-1.el8s @cs8-extras-common
centos-release-storage-common.noarch 2-2.el8 @cs8-extras
centos-release-stream.x86_64 8.1-1.1911.0.7.el8 @cs8-extras
centos-release-virt-common.noarch 1-2.el8 @cs8-extras
vdsm.x86_64 4.50.5.1-1.el8 @centos-ovirt45
The problem has been "solved" by downgrading all qemu-* packages to the
version in AlmaLinux 8.8
ie. qemu-kvm-6.2.0-40.module_el8.9.0+3681+41cbbcc0.1.alma.1 =>
qemu-kvm-6.2.0-33.module_el8.8.0+3612+f18d2b89.alma.1.x86_64
Please find the relevent log:

Configure OVN for oVirt failing - vdsm.tool.ovn_config.NetworkNotFoundError: hostname
by huw.m＠twinstream.com
Hello,
When installing the self-hosted engine using rocky 9 as a host (using nightly builds), the install gets as far as running the below ansible task from ovirt-engine
- name: Configure OVN for oVirt
ansible.builtin.command: >
vdsm-tool ovn-config {{ ovn_central }} {{ ovn_tunneling_interface }} {{ ovn_host_fqdn }}
This command gets executed as vdsm-tool ovn-config 192.168.57.4 hostname.my.project.com
and fails with error
"stderr" : "Traceback (most recent call last):\n File \"/usr/lib/python3.9/site-packages/vdsm/tool/ovn_config.py\", line 117, in get_network\n return networks[net_name]\nKeyError: 'virt-1.local.hyp.twinstream.com'\n\nDuring handling of the above exception, another exception occurred:\n\nTraceback (most recent call last):\n File \"/usr/bin/vdsm-tool\", line 195, in main\n return tool_command[cmd][\"command\"](*args)\n File \"/usr/lib/python3.9/site-packages/vdsm/tool/ovn_config.py\", line 63, in ovn_config\n ip_address = get_ip_addr(get_network(network_caps(), net_name))\n File \"/usr/lib/python3.9/site-packages/vdsm/tool/ovn_config.py\", line 119, in get_network\n raise NetworkNotFoundError(net_name)\nvdsm.tool.ovn_config.NetworkNotFoundError: hostname.my.project.com"

bond0 was selected as the ovirtmgmt bridge NIC. It currently only has one member interface eth2 using balance-xor. In the ovirt management console I can the see host in a down state and given the rest of the playbook ran which requires ssh connectivity between hosted-engine and host, I believe the network is generally setup correctly.
No other immediate errors I can. As vdsm-tool ovn-config expects a network to exist with value of the hostname, what is meant to be creating this on the host?
Thanks,

how to renew expired ovirt node vdsm cert manually ?
by dhanaraj.ramesh＠yahoo.com
below are the steps to renew the expired vdsm cert of ovirt node
# To check CERT expired
# openssl x509 -in /etc/pki/vdsm/certs/vdsmcert.pem -noout -dates
1. Backup vdsm folder
# cd /etc/pki
# mv vdsm vdsm.orig
# mkdir vdsm ; chown vdsm:kvm vdsm
# cd vdsm
# mkdir libvirt-vnc certs keys libvirt-spice libvirt-migrate
# chown vdsm:kvm libvirt-vnc certs keys libvirt-spice libvirt-migrate
2. Regenerate cert & keys
# vdsm-tool configure --module certificates
3. Copy the cert to destination location
chmod 440 /etc/pki/vdsm/keys/vdsmkey.pem
chown root /etc/pki/vdsmcerts/*pem
chmod 644 /etc/pki/vdsmcerts/*pem
cp /etc/pki/vdsm/certs/cacert.pem /etc/pki/vdsm/libvirt-spice/ca-cert.pem

Hi.
We have an Ovirt system, today I updated the engine to v4.5.5, the engine uses self-signed certs/CA.
After the update (and engine-setup) I checked cert expiry dates

I thought that Ovirt should auto update these when using engine-setup ?
I manually updated apache cert using info from -> https://access.redhat.com/solutions/3329431 - i.e /usr/share/ovirt-engine/bin/pki-enroll-pkcs12.sh --name=apache --password="@PASSWORD@" --subject="${SUBJECT}"
How can I update the websocket cert also ?
Any help would be welcomed - thanks
