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]
Mar 1 11:49:06 srvXX abrt-hook-ccpp: invalid number 'iothread1'

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.

Deploy oVirt Engine fail behind proxy
by Matteo Bonardi
Hi,
I am trying to deploy the ovirt engine following self-hosted engine installation procedure on documentation.
Deployment servers are behind a proxy and I have set it in environment and in yum.conf before run deploy.
Deploy fails because ovirt engine vm cannot resolve AppStream repository url:

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.

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

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.

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
cp /etc/pki/vdsm/keys/vdsmkey.pem /etc/pki/vdsm/libvirt-spice/server-key.pem

cp -p /etc/pki/vdsm/certs/cacert.pem /etc/pki/CA/cacert.pem
3. cross check the backup folder /etc/pki/vdsm.orig vs /etc/pki/vdsm
# refer to /etc/pki/vdsm.orig/*/ and set the correct owner & group permission in /etc/pki/vdsm/*/
4. restart services # Make sure both services are up

oVirt 4.5.0.8-1.el8
I tried to connect to grafana via the monitoring portal link from the dash
and all panels are failing to display any data with varying error messages,
but all include 'Origin Not Allowed'
I navigated to Data Sources and ran a test on the PostgreSQL connection
(localhost) which threw the same Origin Not Allowed error message.
Any suggestions?
