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:
[ INFO ] TASK [ovirt.engine-setup : Install oVirt Engine package]

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?

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.

4.4.9 -> 4.4.10 Cannot start or migrate any VM (hotpluggable cpus requested exceeds the maximum cpus supported by KVM)
by Jillian Morgan
After upgrading the engine from 4.4.9 to 4.4.10, and then upgrading one
host, any attempt to migrate a VM to that host or start a VM on that host
results in the following error:
Number of hotpluggable cpus requested (16) exceeds the maximum cpus
supported by KVM (8)
While the version of qemu is the same across hosts, (
qemu-kvm-6.0.0-33.el8s.x86_64), I traced the difference to the upgraded
kernel on the new host. I have always run elrepo's kernel-ml on these hosts
to support bcache which RHEL's kernel doesn't support. The working hosts
still run kernel-ml-5.15.12. The upgraded host ran kernel-ml-5.17.0.
In case anyone else runs kernel-ml, have you run into this issue?
Does anyone know why KVM's KVM_CAP_MAX_VCPUS value is lowered on the new
kernel?
Does anyone know how to query the KVM capabilities from userspace without
writing a program leveraging kvm_ioctl()'s?
Related to this, it seems that ovirt and/or libvirtd always runs qmu-kvm
with an -smp argument of "maxcpus=16". This causes qemu's built-in check to
fail on the new kernel which is supporting max_vpus of 8.
Why does ovirt always request maxcpus=16?
And yes, before you say it, I know you're going to say that running
kernel-ml isn't supported.

Hi,
I have a 3-node oVirt cluster. I have configured 2 logical networks:
ovirtmgmt and public. Public logical network is attached in only 2 nodes
and failing to attach on the 3rd node with the below error
Invalid operation, out-of-sync network 'public' can only be detached.
Please have been stuck on this for almost the whole day now. How do I fix
this error?
