Hi:
I use novnc console can connect to engine vm.
But when I using novnc console connect to other vm in other datacenter,
failed.
The ovirt-websocket-proxy log is:

Guest don't start : Cannot access backing file
by Lionel Caignec
Hi,
i've a big problem, i juste shutdown (power off completely) a guest to make a cold restart. And at startup the guest say : "Cannot access backing file '/rhev/data-center/mnt/blockSD/69348aea-7f55-41be-ae4e-febd86c33855/images/8224b2b0-39ba-44ef-ae41-18fe726f26ca/ca141675-c6f5-4b03-98b0-0312254f91e8'"
When i look from shell on Hypervisor the device file is red blinking...
Trying to change SPM, look device into all hosts, copy disk etc... no way to get my disk back online. It seems ovirt completely lost (delete?) the block device.
There is a way to manually dump (dd) the device in command line in order to import it inside ovirt?
My environment
Storage : SAN (managed by ovirt)
Ovirt-engine 4.4.3.12-1.el8
Host centos 8.2
Vdsm 4.40.26
Thanks for help i'm stuck and it's really urgent

3 node cluster. Gluster for shared storage.

Updated to CentOS 8 Streams :P -> https://bugzilla.redhat.com/show_bug.cgi?id=1911910
After several weeks .. I am really in need of direction to get this fixed.
I saw several postings about oVirt package issues but not found a fix.

Questions:
1) I have two important VMs that have snapshots that I need to boot up. Is their a means with an HCI configuration to manually start the VMs without oVirt engine being up?
2) Is their a means to debug what is going on with the engine failing to start to repair (I hate reloading as the only fix for systems)
3) Is their a means to re-deploy HCI setup wizard, but use the "engine" volume and so retain the VMs and templates?

VG issue / Non Operational
by Christian Reiss
Hey folks,
quick (I hope) question: On my 3-node cluster I am swapping out all the
SSDs with fewer but higher capacity ones. So I took one node down
(maintenance, stop), then removed all SSDs, set up a new RAID, set up
lvm and gluster, let it resync. Gluster health status shows no unsynced
entries.
Uppon going from maintenance to online from ovirt management It goes
into non-operational status, vdsm log on the node shows:

I assume due to the changed LVM UUID it fails, right? Can I someone
fix/change the UUID and get the node back up again? It does not seem to
be a major issue, to be honest.
I can see the gluster mount (what ovirt mounts when it onlines a node)
already, and gluster is happy too.
Any help is appreciated!

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. :)

Q: Node SW Install from oVirt Engine UI Failed
by Andrei Verovski
Hi,
I installed fresh CentOS Stream on HP ProLiant and now trying to install Node SW from oVirt Engine WEB UI.
Software installation failed but no comprehensive description displayed in WEB UI.
Where I can find detailed logs what’s going wrong?
On node "sudo dnf repolist —all” lists required repos, with unnecessary disabled.
Thanks in advance.
Andrei.

About Translation
by Reyhan Gülçetin
Hello,
I'm Reyhan! I am a third-grade physics engineering student in Turkey, I
also worked as a part-time system administration in the university's IT
Head Office until last month. (Now I'm more into DevOps). Back in there, I
was responsible for understanding how we can apply oVirt to our IT Office,
so I was scrolling through the documentations. I've decided to contribute,
oVirt could be the project I used the most, since I'm not a bug-fixer, at
least I can help with the translation. I'm a native Turkish speaker, so I
thought it would go well.
I wish you the best,
Best regards.
Reyhan Gülçetin.

how to install hosted-engine without internet connection ?
by tommy
Hi,every one!
My env cannot access internet, but during the hosted-engine installation, It
needs to run yum install to update system.
I have made a yum source mirror local, but there is a step ( after create
engine vm, the vm runs yum update using default repo configure ) it failed
to connect yum source.
How can I configure yum source to local yum server before the vm run update
?
Thanks.

It seems to have failed in:

This is Oracle-specific code, not part of oVirt. I suggest that you
contact Oracle.

This time I setup a bridge BR0 and disable EM1 (the first Ethernet interface on the host), and then created Bond0 on-top of BR0. Both Bond0 and EM2 (the second Ethernet interface on the host) were up. And then I tried again using Ovirt-Cockpit wizard, with the Engine VM set on BR0, and the deployment of Engine VM simply failed. The Engine and Host are using the same network numbers (192.168.2.0/24) and they resolved correctly. I read the logs in var/log/ovirt-engine/engine.log but there wasn't any error reported.

Disaster Recovery using Ansible roles
by Henry lol
Hi,
I have 2 questions about Disaster Recovery with Ansible.
1)
regarding Ansible failover, AFAIK, a mapping file must be generated before
running failover.
then, should I periodically generate a new mapping file to reflect the
latest structure of the environment?
2)
I guess Ansible failover uses OVF_STOREs to restore the environment and
OVF_STOREs in storage domains are updated every 1 min as default.
then, how to recover the changes made in the meantime?
