How to restore Storage Domain from disaster recovery
by miguel.garcia＠toshibagcs.com
My engine drop dead so had to create a new one and I'm trying to recover virtual drives from previous engine. I'm using next instructions to import storage domain https://www.ovirt.org/develop/release-management/features/storage/imports... but in order to do it well need to unattach storage domain from previous engine which that is not possible right now since the engine has died. Anyway discarting requirements I got the following warning message:
This operation might be unrecoverable and destructive!
Storage Domain(s) are already attached to a Data Center. Aproving this operation might cause data corruption if both Data Centers are Active.
Do you have an idea how to deactivate a Storage domain without ovirt-engine?
Is there any chance to export virtual drives as backups without engine?
Thanks in advance.

oVirt 4.4.4 not dislaying Sign-on Screen
by louisb＠ameritech.net
I recently installed oVirt 4.4.4, everything appeared to run successfully, however, I’m unable to get the sign-on screen to display on my RHEL 8.3 machine. I did do an install using the remote database installation. I encountered no issue with the install, I can see the “engine” and “ovirt_engine_history” in PostgreSQL 13.3. The tables and table spaces have all been created as designed by the installation process.
When I enter the URL that was displayed once the installation completed I get the following information displayed on the screen:
Internal Error
I’ve tried using the port 443 and port 80 URL and get the same results. The URL are as follows:
http://WorkstationName:80/ovirt-engine
https://WorkstationName:443/ovirt-engine
For three days I’ve been trying to locate logs that will help me located and resolve the problem, but so far I’ve had no luck.
Can anyone tell where I should start looking to resolve my issue? I’ve checked several system logs and logs for Apache with luck. What should I be looking for within the logs? What logs should I be looking at?
I don’t believe my issue is with the back-end database, I thinks its something with Apache not being able to find the web pages to display. How can I start to investigate my problem an develop a solution?
My Linux/RHEL 8.3 OS has all of the latest patches and fixes applied.
Thanks

Yes, several times. Also different browsers with no difference.

Sure. Adding the screenshot in this e-mail. This happens after
authenticating like admin (internal) on either the administration panel
or the VM portal.
Thanks.

Engine Upgrade to 4.4.5 Version Number Question
by Nur Imam Febrianto
I’m currently trying to upgrade our cluster from 4.4.4 to 4.4.5. All using oVirt Node.
All host are successfully upgraded to 4.4.5 (I can see the image layer was changed from 4.4.4 to 4.4.5, cockpit also shows same version), but in Engine VM, already run engine-upgrade-check, upgrading ovirt-setup, running engine-setup successfully, reboot the engine but whenever I open the engine web page, it still showing Version 4.4.4.5-1.el8. Is this version correct ? Because my second Cluster that use their own hosted engine shows different version (4.4.5.11-1.el8). Anybody having a same issues like me ?
Thanks before.

Sorry, this is looks like a bug, caused by [1]. Would you like to
report it on bugzilla?
I think a workaround is to run engine-setup like this:
# engine-setup --otopi-environment=OVESETUP_SYSTEM/selinuxBooleans=multi-str:\
The shell will prompt with '> '. Just press Enter.
Martin - seems like I was wrong when commenting on [1] that it seems harmless...
Marcin: we should probably add separate-dwh to ovirt-system-tests or
something like that.

Sorry and best regards,

Hi,
What is the most simpliest way to backward migrate VMs from oVirt 4.4 to oVirt 4.3 ?
Is it possible to use export domain or there are some other ways ?
Thank you.

EMC Unity300 with iSCSI
by Dan Yasny
Hi all,
I've got a brand new Unity300 that I'm trying to hook up to a 4.3 setup
with iSCSI.
The way I have it organized is simple:
- each hypervisor has two NICs set to 192.168.10.x and 192.168.20.x
- the SAN has 4 ports on each controller (A and B), amounting to 8 portal
IPs I can log into.
The problem with the EMC is that at any time, only either A or B addresses
would be active, so I can only login to 4 out of the 8 addresses, while the
engine, in order to add all the possible target IQNs needs to log into all
8 of them.
I've been trying to find a solution for a while now, EMC generally suggest
I use powerpath (not an option here obviously).
Did anyone set up one of these EMC boxes with oVirt before?
Thanks

Accidentally changed VM Assigned Bridge for Hosted-Engine
by phunyguy＠neverserio.us
Hello, exactly as the title suggests, I did something stupid, and I am not sure how to fix this. I also cannot be certain that this was the exact cause of the problem, as I was troubleshooting another issue with a different VM refusing to start.
What I did by accident, was selected the hosted-engine VM, rather than the VM I was attempting to troubleshoot, and changed the assigned network of the VM adapter to something else, and of course, lost connectivity to the engine VM. This caused HA to kick in and restart the engine, however, like the other VM, it is now refusing to start.
Can anyone give me any pointers? agent/broker/vdsm.log are not showing anything useful that I can see. Thanks in advance.

Problem-VDSM command failed:Received fatal alert certificate_expire

Recently Ovirt sent certificate expiration messages. And it does not let me manage the server VMs, I have looked for information about this and I can not find something that is clear. The version of Ovirt that I own is 3.6.3.4-1.el7.cents. I have at least 4 operational VMs of vital importance.
Thanks for the support
