4.5.0.1 ovirt hosted-engine deployment fails
by Mohamed Roushdy
Hello,
I’ve researched a bit about this problem, but none of the proposed solutions fixed it. I’m trying to deploy Ovirt 4.5.0.1 in my lab, and the installation fails with the following error:
[cid:image001.png@01D85BDF.87978B40]
I’ve even tried to delete the default network bridge (as suggested in some articles), but this didn’t help either. The node has 3 network interfaces, and the hosts file points only to the management interface.
Thank you,

unable to upgrade engine to 4.4.10 from 4.4.8
by Diggy Mc
I am unable to upgrade my hosted engine from version 4.4.8 to 4.4.10. I suspect the problem is because of the obsolescence of CentOS Linux 8.
DNF gives me the following error:

This is the list of repositories on my engine:

Q: Cluster compatibility Level and Old v4.2 Nodes
by Andrei Verovski
Hi,
I have quite old nodes from early 4.x era (with CentOS 7.6, cluster compatibility 4.2 level), and oVirt Engine 4.4.
2 nodes have ovirt-release42.
Upgrade to oVirt Engine 4.5 engine required cluster compatibility >= 4.3 level.
Nodes have been installed with stock CentOS 7.6, not oVirt node image, their upgrade is quite problematic right now.
Is it possible to upgrade to cluster compatibility 4.3 while having old 4.2 nodes?
Thanks in advance.

Storage Domain cloned on iscsi storage and import into oVirt
by Gianluca Gargiulo
Hi,
we have this problem:
- Storage Domain iSCSI with a lot of VMs
- on iSCSI SAN there is a iSCSI Target with LUN, snapshotted
We need to revert only one VM from snapshot.
If i revert the snapshot on LUN we revert also other VMs.
If i clone the snapshot in the other LUN and attach it to another iscsi
target, oVirt can't import "new" storage domain, becouse the
VolumeGroupID is same, also

oVirt Engine Deployment, Networking and Nested Virtualization with VMware Fusion 12.x
by mail＠sunilpatel.co.uk
Hello,
I'm just writing my experiences in case others have come across similar issues or have a similar configuration.
I have a single PC, well iMac, home lab environment with VMware Fusion 12.x for Virtualisation. I have tried to setup oVirt 4.5 as a self-hosted engine, deployed on an oVirt 4.5.0 node VM (with nested virtualisation) and the engine deployment fails at this point:
[ INFO ] TASK [ovirt.ovirt.hosted_engine_setup : Get local VM IP]
[ ERROR ] fatal: [localhost]: FAILED! => {"attempts": 90, "changed": true, "cmd": "virsh -r net-dhcp-leases default | grep -i 00:16:3e:36:90:88 | awk '{ print $5 }' | cut -f1 -d'/'", "delta": "0:00:00.052065", "end": "2022-04-27 21:12:08.176323", "msg": "", "rc": 0, "start": "2022-04-27 21:12:08.124258", "stderr": "", "stderr_lines": [], "stdout": "", "stdout_lines": []}
This seems to be the point where the oVirt Engine has gone though an initial deployment and Ansible is trying to get the IP of the ovirt engine to resume configuration and testing. I believe the VM is running on the oVirt node at this point and there is a Linux bridge between the oVirt node and engine VM. The oVirt node itself has two vNICs, one as the oVirt management network and a second unconfigured NIC to be used for Gluster storage. I access oVirt nodes and Cockpit via a "client" linux VM also on the oVirt management network.
It feels like it's this Linux bridge and networking which is not working correctly and causing the deployment to fail. This could be due to the fact that I'm using a virtualised NIC and while promiscuous mode and perhaps some other features are sort-of supported, features needed for this kind of complex networking are not. This is despite the network I'm using being an internal one without the iMAC host connected. WAN connections for oVirt are via a NAT gateway/firewall VM that has the LAN side on the oVirt management network and the WAN side using a bridge with the hosts's NIC (wifi in my case).
I did get similar results when I tried to set up OpenStack Neutron Networking; I could not get traffic to cross the Linux Bridge from one Compute Node VM to another. There are a small handful of results of other people coming across this same issue/error and many of them are also using nested Virtualisation either in ESXi, VirtualBox etc
The Linux Bridge created by the oVirt engine deployment is (from Cockpit):
virbr0Bridge 52:54:00:8F:28:3A
Status
192.168.222.1/24, fe80:0:0:0:5054:ff:fe8f:283a/64, fd00:1234:5678:900:0:0:0:1/64

Bridge
Spanning tree protocol
Forward delay 2
I have actually seen traffic cross this bridge while watching the stats as the engine was being deployed.
If anyone has experienced this problem before and is certain it is due to having a virtualised network, then please let me know. Alternatively, if there is a workaround, that would be great, otherwise I can do more troubleshooting on request but it does feel like this is ultimately a problem related to the platform I'm using - which would not be encountered in a production environment.
Thanks

Q: Non-Operational Node Hosts - Ghost Network Problem
by Andrei Verovski
Hi,
I run into nasty and unexpected problem (oVirt 4.4.7.6-1.el8 ) and 2 non-operational node hosts, which seem relate to ghost network glitch.
Everything worked fine for a very long time until I did the following.
1) Made a backup of several VMs which have network “CloudLink-ISP2”.
2) Moved VM disks into another node hosts, which don’t have link “CloudLink-ISP2”, and forgot (preliminary to move) to re-configure network interface (remove link to “CloudLink-ISP2”) as I did before..
3) Now I have 2 hosts in non-operational mode which is a really big problem - there are only 3 nodes total in a cluster.
I tried to fix this by adding 3rd network “CloudLink-ISP2” to each non-operational hosts, and connected ethernet interfaces to a switch.
Unfortunately, it didn’t helped either because for whatever reason link did not go up.
How I can remove any reference to “CloudLink-ISP2” from node11 and node14? They don’t have any VMs needed that “CloudLink-ISP2”. I edited even inactive VMs and removed “CloudLink-ISP2”.
May be there is an option to ignore missing or downed links whn activating node hosts?
Thanks in advance for any help.

renewing hosts certs when they have expired
by Nathanaël Blanchet
Hello,
I have read some posts about renewing ovirt CA on the engine when it has
expired with engine-setup --offline, but nothing about renewing hosts
certificates when they have expired.
In such a case, we can't interact anymore with hosts and vms are in an
unknown state. The formal solution is to put the concerned host into
maintenance and enroll certificate, but it implies to stop vms.
Here are some messages we can find
For those who are concerned, I wrote an ansible role following
https://access.redhat.com/solutions/3532921
https://galaxy.ansible.com/natman/ovirt_renew_certs
Let me know if it fits to your needs.
