Running oVirt 4.4.5
VM cannot migrate between hosts.
vdsm.log contains the following error:
libvirt.libvirtError: operation failed: Failed to connect to remote libvirt URI qemu+tls://ovhost01.local/system: authentication failed: Failed to verify peer's certificate
Certificates on hosts was renewed some time ago. How this issue can be fixed ?

How to re-enroll (or renew) host certificates for a single-host hosted-engine deployment?
by Derek Atkins
Hi,
I've got a single-host hosted-engine deployment that I originally
installed with 4.0 and have upgraded over the years to 4.3.10. I and some
of my users have upgraded remote-viewer and now I get an error when I try
to view the console of my VMs:
(remote-viewer:8252): Spice-WARNING **: 11:30:41.806:
../subprojects/spice-common/common/ssl_verify.c:477:openssl_verify: Error
in server certificate verification: CA signature digest algorithm too weak
(num=68:depth0:/O=<My Org Name>/CN=<Host's Name>)
I am 99.99% sure this is because the old certs use SHA1.
I reran engine-setup on the engine and it asked me if I wanted to renew
the PKI, and I answered yes. This replaced many[1] of the certificates in
/etc/pki/ovirt-engine/certs on the engine, but it did not update the
Host's certificate.
All the documentation I've seen says that to refresh this certificate I
need to put the host into maintenance mode and then re-enroll.. However I
cannot do that, because this is a single-host system so I cannot put the
host in local mode -- there is no place to migrate the VMs (let alone the
Engine VM).
So.... Is there a command-line way to re-enroll manually and update the
host certs? Or some other way to get all the leftover certs renewed?
Thanks,
-derek
[1] Not only did it not update the Host's cert, it did not update any of
the vmconsole-proxy certs, nor the certs in /etc/pki/ovirt-vmconsole/, and
obviously nothing in /etc/pki/ on the host itself.

4.5.4 with Ceph only storage
by Maurice Burrows
Hey ... A long story short ... I have an existing Red Hat Virt / Gluster hyperconverged solution that I am moving away from.
I have an existing Ceph cluster that I primarily use for OpenStack and a small requirement for S3 via RGW.
I'm planning to build a new oVirt 4.5.4 cluster on RHEL9 using Ceph for all storage requirements. I've read many online articles on oVirt and Ceph, and they all seem to use the Ceph iSCSI gateway, which is now in maintenance, so I'm not real keen to commit to iSCSI.
So my question is, IS there any reason I cannot use CephFS for both hosted-engine and as a data storage domain?
I'm currently running Ceph Pacific FWIW.

i can't access console with noVNC or VNC client(console.vv)
by z84614242＠163.com
i installed the ovirt 4.5 engine on centos stream 9 and add a ovirt node(ovirt node 4.5 iso) to this engine. i am going to run my vm on this node. i follow the instruction to create the data center, the cluster, the storage domain, upload the image. everything is fine. and after i create a vm with ubuntu image attach, i found that i can't visit the console. when i using the noVNC, it says "Something went wrong, connection is closed", when i visit vnc with virt-viewver, is says "Failed to complete handshake Error in the pull function". i try to change the console type to Bochs one and it appear the same. i change to QXL mode and the vm can't start any more. i check the log, it says "unsupported configuration: domain configuration does not support video model 'qxl'".
so now i can't visit my vm by anyway. i deploy the engine follow the official instruction and keep mostly option default but why still have this issue. why the noVNC says "Something went wrong" instead of telling me what is actually wrong

Changing disk QoS causes segfault with IO-Threads enabled (oVirt 4.3.0.4-1.el7)
by jloh＠squiz.net
We recently upgraded to 4.3.0 and have found that when changing disk QoS settings on VMs whilst IO-Threads is enabled causes them to segfault and the VM to reboot. We've been able to replicate this across several VMs. VMs with IO-Threads disabled/turned off do not segfault when changing the QoS.
Mar 1 11:49:06 srvXX kernel: IO iothread1[30468]: segfault at fffffffffffffff8 ip 0000557649f2bd24 sp 00007f80de832f60 error 5 in qemu-kvm[5576498dd000+a03000]

Happy to supply some more logs to someone if they'll help but just wondering whether anyone else has experienced this or knows of a current fix other than turning io-threads off.
Cheers.

Cannot restart ovirt after massive failure.
by Gilboa Davara
Hello all,
During the night, one of my (smaller) setups, a single node self hosted
engine (localhost NFS) crashed due to what-looks-like a massive disk
failure (Software RAID6, with 10 drives + spare).
After a reboot, I let the RAID resync with a fresh drive) and went on to
start oVirt.
However, no such luck.
Two issues:
1. ovirt-ha-broker fails due to broken hosted engine state (log attached).
2. ovirt-ha-agent fails due to network test (tcp) even though both
remote-host and DNS servers are active. (log attached).
Two questions:
1. Can I somehow force the agent to disable the network liveliness test?
2. Can I somehow force the broker to rebuild / fix the hosted engine state?

Please, Please Help - New oVirt Install/Deployment Failing - "Host is not up..."
by Matthew J Black
Hi Everyone,
Could someone please help me - I've been trying to do an install of oVirt for *weeks* (including false starts and self-inflicted wounds/errors) and it is still not working.
My setup:
- oVirt v4.5.3
- A brand new fresh vanilla install of RockyLinux 8.6 - all working AOK
- 2*NICs in a bond (802.3ad) with a couple of sub-Interfaces/VLANs - all working AOK
- All relevant IPv4 Address in DNS with Reverse Lookups - all working AOK
- All relevant IPv4 Address in "/etc/hosts" file - all working AOK
- IPv6 (using "method=auto" in the interface config file) enabled on the relevant sub-Interface/VLAN - I'm not using IPv6 on the network, only IPv4, but I'm trying to cover all the bases.
- All relevant Ports (as per the oVirt documentation) set up on the firewall
- ie firewall-cmd --add-service={{ libvirt-tls | ovirt-imageio | ovirt-vmconsole | vdsm }}
- All the relevant Repositories installed (ie RockyLinux BaseOS, AppStream, & PowerTools, and the EPEL, plus the ones from the oVirt documentation)
I have followed the oVirt documentation (including the special RHEL-instructions and RockyLinux-instructions) to the letter - no deviations, no special settings, exactly as they are written.
All the dnf installs, etc, went off without a hitch, including the "dnf install centos-release-ovirt45", "dnf install ovirt-engine-appliance", and "dnf install ovirt-hosted-engine-setup" - no errors anywhere.
Here is the results of a "dnf repolist":
- appstream Rocky Linux 8 - AppStream
- baseos Rocky Linux 8 - BaseOS
- centos-ceph-pacific CentOS-8-stream - Ceph Pacific
- centos-gluster10 CentOS-8-stream - Gluster 10
- centos-nfv-openvswitch CentOS-8 - NFV OpenvSwitch
- centos-opstools CentOS-OpsTools - collectd
- centos-ovirt45 CentOS Stream 8 - oVirt 4.5
- cs8-extras CentOS Stream 8 - Extras
- cs8-extras-common CentOS Stream 8 - Extras common packages
- epel Extra Packages for Enterprise Linux 8 - x86_64
- epel-modular Extra Packages for Enterprise Linux Modular 8 - x86_64
- ovirt-45-centos-stream-openstack-yoga CentOS Stream 8 - oVirt 4.5 - OpenStack Yoga Repository
- ovirt-45-upstream oVirt upstream for CentOS Stream 8 - oVirt 4.5
- powertools Rocky Linux 8 - PowerTools
So I kicked-off the oVirt deployment with: "hosted-engine --deploy --4 --ansible-extra-vars=he_offline_deployment=true".
I used "--ansible-extra-vars=he_offline_deployment=true" because without that flag I was getting "DNF timout" issues (see my previous post `Local (Deployment) VM Can't Reach "centos-ceph-pacific" Repo`).
I answer the defaults to all of questions the script asked, or entered the deployment-relevant answers where appropriate. In doing this I double-checked every answer before hitting <Enter>. Everything progressed smoothly until the deployment reached the "Wait for the host to be up" task... which then hung for more than 30 minutes before failing.
From the ovirt-hosted-engine-setup... log file:
- 2022-10-20 17:54:26,285+1100 ERROR otopi.ovirt_hosted_engine_setup.ansible_utils ansible_utils._process_output:113 fatal: [localhost]: FAILED! => {"changed": false, "msg": "Host is not up, please check logs, perhaps also on the engine machine"}
I checked the following log files and found all of the relevant ERROR lines, then checked several 10s of proceeding and succeeding lines trying to determine what was going wrong, but I could not determine anything.
- ovirt-hosted-engine-setup...
- ovirt-hosted-engine-setup-ansible-bootstrap_local_vm...
- ovirt-hosted-engine-setup-ansible-final_clean... - not really relevant, I believe
I can include the log files (or the relevant parts of the log files) if people want - but that are very large: several 100 kilobytes each.
I also googled "oVirt Host is not up" and found several entries, but after reading them all the most relevant seems to be a thread from these mailing list: `Install of RHV 4.4 failing - "Host is not up, please check logs, perhaps also on the engine machine"` - but this seems to be talking about an upgrade and I didn't gleam anything useful from it - I could, of course, be wrong about that.
So my questions are:
- Where else should I be looking (ie other log files, etc, and possible where to find them)?
- Does anyone have any idea why this isn't working?
- Does anyone have a work-around (including a completely manual process to get things working - I don't mind working in the CLI with virsh, etc)?
- What am I doing wrong?
Please, I'm really stumped with this, and I really do need help.
Cheers

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

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,
Huw
