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:
2020-05-27 00:17:08,886+0200 DEBUG

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!

VM with illegal snapshots
by Giorgio Biacchi
Hi,
due to a bug in our Ovirt integrated backup system now we have some VMs
with snapshots in illegal state.
It seems that there's an inconsistency between the db and the real
status of images on disk.
Let me show an example:
engine=# select
image_guid,parentid,imagestatus,vm_snapshot_id,volume_type,volume_format,active
from images where image_group_id='e34f77cb-54d5-40d0-b539-e0a5fd512d2d';
image_guid | parentid |
imagestatus | vm_snapshot_id | volume_type |
volume_format | active

so image guid a4c86a68-9123-454c-b417-1b15038a4bf2 is not present on
disk, i think that the image was correctly merged but not removed from
the database.
Any suggestion on how to fix the database to reflect the real situation
on disk??
TIA

rhv 4.3.11 but not ovirt 4.3.11
by Gianluca Cecchi
Hello,
I see that a 4.3.11 version is available for downstream RHV but not for
upstream oVirt.
Will it be released for oVirt too?
Are there only security fixes inside or also bug fixes (like the few lines
one related to export as OVA)?
Thanks,
Gianluca

Single Node HCI upgrade procedure from CentOS7/oVirt 4.3 to CentOS8/oVirt 4.4?
by thomas＠hoberg.net
I can hear you saying: "You did understand that single node HCI is just a toy, right?"
For me the primary use of a single node HCI is adding some disaster resilience in small server edge type scenarios, where a three node HCI provides the fault tolerance: 3+1 with a bit of distance, warm or even cold stand-by, potentially manual switch and reduced workload in case disaster strikes.
Of course, another 3nHCI would be better, but who gets that type of budget, right?
What I am trying say: If you want oVirt to gain market share, try to give HCI more love. And while you're at it, try to make expanding from 1nHCI to 3nHCI (and higher counts) a standard operational procedure to allow expanding a disaster stand-by into a production setup, while the original 3nHCI is being rebuilt.
For me low-budget HCI is where oVirt has its biggest competitive advantage against vSan and Nutanix, so please don't treat the HCI/gluster variant like an unwanted child any more.
In the mean-time OVA imports (from 4.3.10 exports) on my 4.4.2 1nHCI fail again, which I'll report separately.

Problem with Cluster-wise BIOS Settings in oVirt 4.4
by Rodrigo G. López
Hi all,
We are running an oVirt 4.4 Hosted Engine as a VM, and after changing
the Cluster's BIOS type from Q35 with Legacy BIOS (the default one after
installation) to Preexistent, the VM fails with the following error:
XML error: The device at PCI address 0000:00:02.0 cannot be plugged into
the PCI controller with index='0'. It requires a controller that accepts
a pcie-root-port.
We need it so that we can run imported VMs from a previous version of
oVirt, namely 4.0.
Applying the BIOS settings individually works but as an attempt to
generalize the settings we decided to apply it to the full cluster.
Tell me if you need more data.
Cheers,

The ovirt manager is 3.6.7
If I create a new datacenter I can attach a lv from the same lun with the problem..
