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":
"0:00:00.108872", "end": "2018-06-01 11:17:34.421769", "rc": 0, "start":
"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,
Florent

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.

did 4.3.9 reset bug https://bugzilla.redhat.com/show_bug.cgi?id=1590266
by kelley bryan
I am experiencing the error message in the ovirt-hosted-engine-setup-ansible-create_target_vm log
{2020-05-06 14:15:30,024-0500 ERROR ansible failed {'status': 'FAILED', 'ansible_type': 'task', 'ansible_task': u"Fail if Engine IP is different from engine's he_fqdn resolved IP", 'ansible_result': u'type: <type \'dict\'>\nstr: {\'msg\': u"Engine VM IP address is while the engine\'s he_fqdn ovirt1-engine.kelleykars.org resolves to 192.168.122.2.

The bug 1590266 says it should report the engine VM IP address xxx.xxx.xxx.xxx while the Engines he_fqdn is xxxxxxxxx
I need to see what it thins is wrong as both dig fqdn engine name and dig -x ip return the correct information.
Now this bug looks like it may play but I don't see the failed rediness check in the this log https://access.redhat.com/solutions/4462431
or is it because the vm fails or dies or ???

Snapshot and disk size allocation
by jorgevisentini＠gmail.com
Hello everyone.
I would like to know how disk size and snapshot allocation works, because every time I create a new snapshot, it increases 1 GB in the VM's disk size, and when I remove the snap, that space is not returned to Domain Storage.
I'm using the oVirt 4.3.10
How do I reprovision the VM disk?
Thank you all.

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?
