Libgfapi considerations
by Jayme
Are there currently any known issues with using libgfapi in the latest
stable version of ovirt in hci deployments? I have recently enabled it and
have noticed a significant (over 4x) increase in io performance on my vms.
I’m concerned however since it does not seem to be an ovirt default
setting. Is libgfapi considered safe and stable to use in ovirt 4.3 hci?

supervdsm failing during network_caps
by Alan G
Hi,
I have issues with one host where supervdsm is failing in network_caps.
I see the following trace in the log.

A restart of supervdsm will resolve the issue for a period, maybe 24 hours, then it will occur again. So I'm thinking it's resource exhaustion or a leak of some kind?
Running 4.2.8.2 with VDSM at 4.20.46.
I've had a look through the bugzilla and can't find an exact match, closest was this one https://bugzilla.redhat.com/show_bug.cgi?id=1666123 which seems to be a RHV only fix.
Thanks,

OVN and change of mgmt network
by Gianluca Cecchi
Hello,
I previously had OVN running on engine (as OVN provider with northd and
northbound and southbound DBs) and hosts (with OVN controller).
After changing mgmt ip of hosts (engine has retained instead the same ip),
I executed again on them the command:
vdsm-tool ovn-config <ip_of_engine> <nel_local_ip_of_host>
Now I think I have to clean up some things, eg:
1) On engine
where I get these lines below
systemctl status ovn-northd.service -l
. . .
Sep 29 14:41:42 ovmgr1 ovsdb-server[940]: ovs|00005|reconnect|ERR|tcp:
10.4.167.40:37272: no response to inactivity probe after 5 seconds,
disconnecting
Oct 03 11:52:00 ovmgr1 ovsdb-server[940]: ovs|00006|reconnect|ERR|tcp:
10.4.167.41:52078: no response to inactivity probe after 5 seconds,
disconnecting
The two IPs are the old ones of two hosts
It seems that a restart of the services has fixed...
Can anyone confirm if I have to do anything else?
2) On hosts (there are 3 hosts with OVN on ip 10.4.192.32/33/34)
where I currently have this output
[root@ov301 ~]# ovs-vsctl show
3a38c5bb-0abf-493d-a2e6-345af8aedfe3
Bridge br-int
fail_mode: secure
Port "ovn-1dce5b-0"

Port "ovn-ddecf0-0"
Interface "ovn-ddecf0-0"
type: geneve
options: {csum="true", key=flow, remote_ip="10.4.192.33"}

Port br-int
Interface br-int
type: internal
ovs_version: "2.7.2"
[root@ov301 ~]#
The IPs of kind 10.4.192.x are ok.
But there is a left-over of an old host I initially used for tests,
corresponding to 10.4.168.74, that now doesn't exist anymore
How can I clean records for 1) and 2)?
Thanks,

CentOS Stream support
by Michal Skrivanek
Hi all,
we would like to ask about interest in community about oVirt moving to CentOS Stream.
There were some requests before but it’s hard to see how many people would really like to see that.
With CentOS releases lagging behind RHEL for months it’s interesting to consider moving to CentOS Stream as it is much more up to date and allows us to fix bugs faster, with less workarounds and overhead for maintaining old code. E.g. our current integration tests do not really pass on CentOS 8.1 and we can’t really do much about that other than wait for more up to date packages. It would also bring us closer to make oVirt run smoothly on RHEL as that is also much closer to Stream than it is to outdated CentOS.
So..would you like us to support CentOS Stream?
We don’t really have capacity to run 3 different platforms, would you still want oVirt to support CentOS Stream if it means “less support” for regular CentOS?
There are some concerns about Stream being a bit less stable, do you share those concerns?
Thank you for your comments,
michal

encrypted GENEVE traffic
by Pavel Nakonechnyi
Dear oVirt Community,
From my understanding oVirt does not support Open vSwitch IPSEC tunneling for GENEVE traffic (which is described on pages http://docs.openvswitch.org/en/latest/howto/ipsec/ and http://docs.openvswitch.org/en/latest/tutorials/ipsec/).
Are there plans to introduce such support? (or explicitly not to..)
Is it possible to somehow manually configure such tunneling for existing virtual networks? (even in a limited way)
Alternatively, is it possible to deploy oVirt on top of the tunneled (i.e. via VXLAN, IPSec) interfaces? This will allow to encrypt all management traffic.
Such requirement arises when using oVirt deployment on third-party premises with untrusted network.
Thank in advance for any clarifications. :)

oVirt 4.4: Self-hosted engine deployment fails with backup restore from 4.3 engine
by Oliver Leinfelder
Hi there,
I'm a bit puzzled about an possible upgrade paths from a 4.3 cluster to
version 4.4 in a self-hosted engine environment.
My idea was:
Set up a new host with a clean ovirt node 4.4 installation, then deploy the
hosted engine on this with a restored backup from the production cluster
and go from there.
This however fails with the following error:

Is this approach (restoring from 4.3) generally supposed to work? If not,

"gluster-ansible-roles is not installed on Host" error on Cockpit
by Hesham Ahmed
On a new 4.3.1 oVirt Node installation, when trying to deploy HCI
(also when trying adding a new gluster volume to existing clusters)
using Cockpit, an error is displayed "gluster-ansible-roles is not
installed on Host. To continue deployment, please install
gluster-ansible-roles on Host and try again". There is no package
named gluster-ansible-roles in the repositories:
[root@localhost ~]# yum install gluster-ansible-roles
Loaded plugins: enabled_repos_upload, fastestmirror, imgbased-persist,
package_upload, product-id, search-disabled-repos,
subscription-manager, vdsmupgrade
This system is not registered with an entitlement server. You can use
subscription-manager to register.
Loading mirror speeds from cached hostfile
* ovirt-4.3-epel: mirror.horizon.vn
No package gluster-ansible-roles available.
Error: Nothing to do
Uploading Enabled Repositories Report
Cannot upload enabled repos report, is this client registered?
This is due to check introduced here:
https://gerrit.ovirt.org/#/c/98023/1/dashboard/src/helpers/AnsibleUtil.js
Changing the line from:
[ "rpm", "-qa", "gluster-ansible-roles" ], { "superuser":"require" }
to
[ "rpm", "-qa", "gluster-ansible" ], { "superuser":"require" }
resolves the issue. The above code snippet is installed at
/usr/share/cockpit/ovirt-dashboard/app.js on oVirt node and can be
patched by running "sed -i 's/gluster-ansible-roles/gluster-ansible/g'
/usr/share/cockpit/ovirt-dashboard/app.js && systemctl restart
cockpit"

ovirt-imageio-proxy not working after updating SSL certificates with a wildcard cert issued by AlphaSSL (intermediate)
by Lynn Dixon
All,
I recently bought a wildcard certificate for my lab domain (shadowman.dev)
and I replaced all the certs on my RHV4.3 machine per our documentation.
The WebUI presents the certs successfully and without any issues, and
everything seemed to be fine, until I tried to upload a disk image (or an
ISO) to my storage domain. I get this error in the events tab:
https://share.getcloudapp.com/p9uPvegx
[image: image.png]
I also see that the disk is showing up in my storage domain, but its
showing "Paused by System" and I can't do anything with it. I cant even
delete it!
I have tried following this document to fix the issue, but it didn't work:
https://access.redhat.com/solutions/4148361
I am seeing this error pop into my engine.log:
https://pastebin.com/kDLSEq1A
And I see this error in my image-proxy.log:
WARNING 2020-07-24 15:26:34,802 web:137:web:(log_error) ERROR [172.17.0.30]
PUT /tickets/ [403] Error verifying signed ticket: Invalid ovirt ticket
(data='------my_ticket_data-----', reason=Untrusted certificate)
[request=0.002946/1]
Now, when I bought my wildcard, I was given a root certificate for the CA,
as well as a separate intermediate CA certificate from the provider.
Likewise, they gave me a certificate and a private key of course. The root
and intermediate CA's certificates have been added
to /etc/pki/ca-trust/source/anchors/ and I did an update-ca-trust.
I also started experiencing issues with the ovpn network provider at the
same time I replaced the SSL certs, but I disregarded it at the time, but
now I am thinking its related. Any advice on what to look for to fix the
ovirt-imageio-proxy?
Thanks!

POWER9 (ppc64le) Support on oVirt 4.4.1
by Vinícius Ferrão
Hello, I was using oVirt 4.3.10 with IBM AC922 (POWER9 / ppc64le) without any issues.
Since I’ve moved to 4.4.1 I can’t add the AC922 machine to the engine anymore, it complains with the following error:
The host CPU does not match the Cluster CPU type and is running in degraded mode. It is missing the following CPU flags: model_POWER9, powernv.
Any ideia of what’s may be happening? The engine runs on x86_64, and I was using this way on 4.3.10.
Machine info:
timebase : 512000000
platform : PowerNV
model : 8335-GTH
machine : PowerNV 8335-GTH
firmware : OPAL
MMU : Radix
