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":

"2018-06-01 11:17:34.312897", "stderr": "", "stderr_lines": [],
"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

Import an exported VM using Ansible
by paolo＠airaldi.it
Hello everybody!
I'm trying to automate a copy of a VM from one Datacenter to another using an Ansible.playbook.
I'm able to:
- Create a snapshot of the source VM
- create a clone from the snapshot
- remove the snapshot
- attach an Export Domain
- export the clone to the Export Domain
- remove the clone
- detach the Export domain from the source Datacenter and attach to the destination.
Unfortunately I cannot find a module to:
- import the VM from the Export Domain
- delete the VM image from the Export Domain.
Any hint on how to do that?
Thanks in advance. Cheers.
Paolo
PS: if someone is interested I can share the playbook.

Template for Ubuntu 18.04 Server Issues
by jeremy_tourville＠hotmail.com
I have built a system as a template on oVirt. Specifically, Ubuntu 18.04 server.
I am noticing an issue when creating new vms from that template. I used the check box for "seal template" when creating the template.
When I create a new Ubuntu VM I am getting duplicate IP addresses for all the machines created from the template.
It seems like the checkbox doesn't fully function as intended. I would need to do further manual steps to clear up this issue.
Has anyone else noticed this behavior? Is this expected or have I missed something?
Thanks for your input!

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.
MainProcess|jsonrpc/1::ERROR::2020-01-06 03:01:05,558::supervdsm_server::100::SuperVdsm.ServerCallback::(wrapper) Error in network_caps

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,
Alan

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

[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,
Gianluca
