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. :)

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 It would also bring us closer to make oVirt run smoothly on RHEL as that is also much closer to Stream than it is to outdated CentOS.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

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!

POWER9 (ppc64le) Support on oVirt 4.4.1
by Vinícius Ferrão
Hello, I was using oVirt 4.3.10 with IBM AC922 (POWER9 / ppc64le) without any issues.
Since I’ve moved to 4.4.1 I can’t add the AC922 machine to the engine anymore, it complains with the following error:
The host CPU does not match the Cluster CPU type and is running in degraded mode. It is missing the following CPU flags: model_POWER9, powernv.
Any ideia of what’s may be happening? The engine runs on x86_64, and I was using this way on 4.3.10.
Machine info:
timebase : 512000000
platform : PowerNV
model : 8335-GTH
machine : PowerNV 8335-GTH

iSCSI multipath issue
by Nick Kas
Hello evryone,
setup ovirt 4.4.1 on CentOS 8.2 as an experiment, and I am trying to get an iSCSI domain working but have issues. The little experimental cluster has 3 hosts. There is an ovirtmgmt network on the default vlan, and two iSCSI network (172.27.0/1.X) with vlans 20/21. ovirtmgmt has all the functions (Data, display, migration etc), and the iSCSI networks nothing yet, and they are not set as required.
The SAN device is already serving a few iSCSI volumes to a vmware cluster, so I know things are fine on this end. It has two controllers, and four NICs per controller so a total of 8 NICs, half of the NICS per controller on 172.27.0.X and half on 172.27.1.X.
When I create the iSCSI domain, I login to only one of the targets, and add the Volume, all is good and I can use the disc fine.
However when I login to more than one of the targets, then I start having issues with the Volume. Even when I enabled multipath in the cluster, and I created a single multipath by selecting both of the 172.27.0/1.X networks, and all the targets, the end result was the same. The hosts have difficulty accessing the volume, they may even swing between 'non-operational' and 'up' if I transfer data to the volume. When I ssh to the hosts and i check things in the command line I also get inconsistent results between hosts, and blocks that appear with lsblk when I first setup iSCSI have dissapeared after I try to actively use the volume.
I am new to iSCSI so I am not sure how to debug this. I am not sure if my multipath configuration is correct or not. The documentation on this part was not very detailed. I also tried to remove the domain, and try to experiment with mounting the iSCSI volume from the command line, but I cannot even discover the target from the command line, which is very bizarre. The command
iscsiadm --mode discovery --target sendtargets --portal 172.27.0.55 --discover
returns the message 'iscsiadm: cannot make connection to 172.27.0.55: No route to host'. Yet through ovirt, and if I select only one target, everything work fine!
Any suggestions on how to start debugging this would really be appreciated.

How to Backup a VM
by Stefan Wolf
Hello to all
I try to backup a normal VM. But It seems that I don't really understand the concept. At first I found the possibility to backup with the api https://www.ovirt.org/documentation/administration_guide/#Setting_a_stora....
Create a snapshot of the VM, finding the ID of the snapshot and the configuration of the VM makes sense to me.
But at this point, I would download the config an the snapshot and put it to my backup storage. And not create a new VM attach the disk and run a backup with backup programm. And for restoring do the sam way backwards.
If i look at other project, there seems do be a way to download the snapshot and configfile, or am I wrong?
Maybe someone can explain to me why I should use additional software to install in an additional machine. Or even better someone can explain to me how I don't have to use additional backup software.
And to the same topic backup.
There is in the documentation the possibility to set up a backup storage
It is nearly the same, create a snapshot, or clone the machine and export it to backup storage
> Export the new virtual machine to a backup domain. See Exporting a Virtual Machine to a Data Domain in the Virtual Machine Management Guide.
Sadly there is just writen what to do, not how, the link points to 404 page. maybe someone can explain to me how to use backup storage
thank you very much
