Planned restart of production services
by Evgheni Dereveanchin
Hi everyone,
I'll be restarting several production systems today to apply security
updates.
The following services may be unreachable for short periods of time:
- resources.ovirt.org - software repositories
- jenkins.ovirt.org - CI master
No new builds will be started during this period.
I will announce you once maintenance is complete.

oVirt/RHV 4.3.6: How to boot a Q35/UEFI VM from CD?
by mathieu.simon＠gymneufeld.ch
Hi
I've been experimenting with UEFI on RHV 4.3.6 using Windows Server 2019 but I guess posting on the oVirt list might reach a wider audience.
I've used UEFI guests on other KVM-based virtualizations, but I have been unable to detect a UEFI-bootable CD using Q35 VMs with or without SecureBoot in RHV 4.3.6 since it doesn't even propose to load the UEFI loader from within OVMF. It seems to show the CD-ROM drive, but I cannot boot from file the disc from OVMF:
Are there any hints? (I've tried finding something more detailed in the Docs though) I'd like investigate UEFI and SecureBoot on oVirt/RHV even if it's still considered a tech preview. (I've been using KVM-based UEFI VM for years already on other platforms and distributions with no particular issues, rather advantages overall).
Regards
Mathieu

What to do with old ovirt yum repos, and why are they kept around?
by Derek Atkins
Hi,
I just upgraded my engine from 4.1.9 to 4.2.8 to 4.3.x yesterday. One
issue I hit along the way was a complaint about repos being listed more
than once:
Repository virtio-win-stable is listed more than once in the configuration
Repository centos-sclo-rh-release is listed more than once in the configuration
I also received errors like:
http://mirror.centos.org/centos/7/storage/x86_64/gluster-3.8/repodata/rep...: [Errno 14] HTTP Error 404 - Not Found
Trying other mirror.
Even after I did a yum erase on ovirt-release40 (and ovirt-release41) I
noticed that the 4.0 and 4.1 yum repositories (and dependencies)
configurations were left in /etc/yum.repos.d/. Is there a reason these
files are not removed when the associated release packages are removed?
Thanks,
-derek

Problem upgrading from 4.1.9 to 4.2.8 -- vmconsole SElinux issue
by Derek Atkins
Hi,
I spent yesterday trying to upgrade my self-hosted, single-host, ovirt
engine from EL7.4/OV4.1.9 to EL7.7/OV4.3.x with a step at EL7.6/OV4.2.8.
Unfortunately that first step was extremely problematic. Specifically,
I kept hitting an issue where the installation ofovirt-vmconsole would
error out with a "non-fatal POSTUN scriptlet failure", which of course
is considered fatal:
2019-10-27 10:42:18,436-0400 DEBUG otopi.plugins.otopi.packagers.yumpackager yum
packager.verbose:76 Yum Done: ovirt-vmconsole
2019-10-27 10:42:18,504-0400 ERROR otopi.plugins.otopi.packagers.yumpackager yum
packager.error:85 Yum Non-fatal POSTUN scriptlet failure in rpm package ovirt-vm
console-1.0.4-1.el7.centos.noarch
2019-10-27 10:42:18,505-0400 DEBUG otopi.plugins.otopi.packagers.yumpackager yum
packager.verbose:76 Yum Done: ovirt-vmconsole-1.0.4-1.el7.centos.noarch
2019-10-27 10:42:18,605-0400 DEBUG otopi.plugins.otopi.packagers.yumpackager yum
packager.verbose:76 Yum Script sink: D: --- h# 747 ovirt-vmconsole-1.0.4-1
.el7.centos.noarch
This appears to be https://bugzilla.redhat.com/show_bug.cgi?id=1665197
which is closed as being fixed in 4.3.1, but that *STILL* doesn't help
when trying to upgrade the engine from 4.1. to 4.2. It should have been
fixed for 4.2.8 (or push a 4.2.9 with the fix).
After googling around, I was able to work around this bug by moving
semodule out of the way:
mv /usr/sbin/semodule{,-bak}
ln -fs /bin/true /usr/sbin/semodule
and then running the update (I reverted after the update). I don't
*like* this solution, but it got it working. I'll note that I have
SELinux set to "enforcing", and I started with EL7.2/OV4.0 and have
upgraded a few times.

Problems with glance.ovirt.org over IPV6.
by Daniel Leite De Abreu
Hi, there hope someone has experienced this situation and can help me further on his matter.
Our current ovirt engine is trying to download images from http://glance.ovirt.org:9292 and the connection work normally whoever for some reason it also tries to download over ipv6 and our network is all based on IPV4 so the error I get is the bellow.
Connecting to glance.ovirt.org (glance.ovirt.org)|2620:52:3:1:5054:ff:fe32:c1d9|:9292... failed: Network is unreachable
I had tried the same from outside our network on a public place that works on IPV6 and I get the same error, as my understanding from the error message I am for some reason now able to reach the destination via IPV6, whoever my goal is to use IPV4 only and I would like to know if there is any way I can disable import or any checks done over ipv6 from glance.ovirt.org ?
Thanks in advance for the support and help on this matter.

Re: Host-passthrough CPU and migration
by Strahil
Ah... Never thought I can switch it to 'Auto'. Actually it makes sense - we can't be sure if all nodes in cluster are the same - like my case.
Now all VMs are in Auto mode.
Thanks for the clarification, Sharon.

Host-passthrough CPU and migration
by Strahil Nikolov
Hello Community,Dev,
does anyone know why only "Manual Migration" allows passing through the CPU from the Host to the VM ?
In many environments, the Clusters are having the same CPU model in order to avoid any issues. Have you observed any issues with that ?
