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"
Interface "ovn-1dce5b-0"
type: geneve
options: {csum="true", key=flow, remote_ip="10.4.192.32"}
Port "ovn-ddecf0-0"
Interface "ovn-ddecf0-0"
type: geneve
options: {csum="true", key=flow, remote_ip="10.4.192.33"}
Port "ovn-fd413b-0"
Interface "ovn-fd413b-0"
type: geneve
options: {csum="true", key=flow, remote_ip="10.4.168.74"}
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:

"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"

Or possibly implicit user session created when running the python script?

Any known problem?

How to extend timeout?

deprecating export domain?
by Charles Kozler
Hello,
I recently read on this list from a redhat member that export domain is
either being deprecated or looking at being deprecated
To that end, can you share details? Can you share any notes/postings/bz's
that document this? I would imagine something like this would be discussed
in larger audience
This seems like a somewhat significant change to make and I am curious
where this is scheduled? Currently, a lot of my backups rely explicitly on
an export domain for online snapshots, so I'd like to plan accordingly
Thanks!

Upgrade Memory of oVirt Nodes
by souvaliotimaria＠mail.com
Hello everyone,
I have an oVirt 4.3.2.5 hyperconverged 3 node production environment and we want to add some RAM to it.
Can I upgrade the RAM without my users noticing any disruptions and keep the VMs running?
The way I thought I should do it was to migrate any running VMs to the other nodes, then set one node in maintenance mode, shut it down, place the new memory, bring it back up, remove it from maintenance mode and see how the installation reacts and repeat for the other two nodes. Is this correct or should I follow another way?
Will there be a problem during the time when the nodes will not be identical in their resources?
Thank you for your time,

Support for Shared SAS storage
by Vinícius Ferrão
Hello,
I’ve two compute nodes with SAS Direct Attached sharing the same disks.
Looking at the supported types I can’t see this on the documentation: https://www.ovirt.org/documentation/admin-guide/chap-Storage.html
There’s is local storage on this documentation, but my case is two machines, both using SAS, connected to the same machines. It’s the VRTX hardware from Dell.
Is there any support for this? It should be just like Fibre Channel and iSCSI, but with SAS instead.
Thanks,
