OVN routing and firewalling in oVirt
by Gianluca Cecchi
Hello,
how do we manage routing between different OVN networks in oVirt?
And between OVN networks and physical ones?
Based on architecture read here:
http://openvswitch.org/support/dist-docs/ovn-architecture.7.html
I see terms for logical routers and gateway routers respectively but how to
apply to oVirt configuration?
Do I have to choose between setting up a specialized VM or a physical one:
is it applicable/advisable to put on oVirt host itself the gateway
functionality?
Is there any security policy (like security groups in Openstack) to
implement?
Thanks,
Gianluca

Install hosted-engine - Task Get local VM IP failed
by florentl
Hi all,
I try to install hosted-engine on node : ovirt-node-ng-4.2.3-0.20180518.
Every times I get stuck on :
[ ERROR ] fatal: [localhost]: FAILED! => {"attempts": 50, "changed":
true, "cmd": "virsh -r net-dhcp-leases default | grep -i
00:16:3e:6c:5a:91 | awk '{ print $5 }' | cut -f1 -d'/'", "delta":

"stdout": "", "stdout_lines": []}
I tried with static IP Address and with DHCP but both failed.
To be more specific, I installed three nodes, deployed glusterfs with
the wizard. I'm in a nested virtualization environment for this lab
(Vmware Esxi Hypervisor).
My node IP is : 192.168.176.40 / and I want the hosted-engine vm has
192.168.176.43.
Thanks,

Host needs to be reinstalled after configuring power management
by Andrew DeMaria
Hi,
I am running ovirt 4.3 and have found the following action item immediately
after configuring power management for a host:
Host needs to be reinstalled as important configuration changes were
applied on it.
The thing is - I've just freshly installed this host and it seems strange
that I need to reinstall it.
Is there a better way to install a host and configure power management
without having to reinstall it after?
Thanks,
Andrew

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-ddecf0-0"

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,

"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"

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!

Re: Single instance scaleup.
by Strahil
Hi Leo,
As you do not have a distributed volume , you can easily switch to replica 2 arbiter 1 or replica 3 volumes.
You can use the following for adding the bricks:

Failed to add storage domain

I have installed oVirt using the iso ovirt-node-ng-installer-4.3.2-2019031908.el7. I the did run the Host-engine deployment through Cockpit.
I got an error when it tries to create the domain storage. It sucessfully mounted the NFS-share on the host. Bellow is the error I got:
