Experience on using HCI with geo-replication for DR
by wodel youchi 07 Apr '21

07 Apr '21

Hi, Does anyone use ovirt HCI with geo-replication for DR? if yes, could you share your experience? We recently did a setup of 2 HCI platforms, and we configured geo-replication between them. The two platforms were configured with encryption and VDO. When testing the DR, we had some surprises : - Sometimes VMs are not imported - Sometimes some VMs are imported others not - Sometimes VMs are imported without their disks - Sometimes deleted items from the source are imported!!! - And sometimes the imported VMs are corrupted.

4.4 -> 4.3
by KSNull Zero 06 Apr '21

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.

Accidentally changed VM Assigned Bridge for Hosted-Engine
by phunyguy＠neverserio.us 06 Apr '21

06 Apr '21

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. -phunyguy

Problem-VDSM command failed:Received fatal alert certificate_expire
by fmendoza＠red.com.sv 06 Apr '21

06 Apr '21

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

Problems after upgrade from 4.4.3 to 4.4.4
by tferic＠swissonline.ch 06 Apr '21

06 Apr '21

Hi I have problems after upgrading my 2-node cluster from 4.4.3 to 4.4.4. Initially, I performed the upgrade of the oVirt hosts using the oVirt GUI (I wasn't planning any changes). It appears that the upgrade broke the system. On host1, the ovirt-engine was configured to run on the oVirt host itself (not self-hosted engine). After the upgrade, the oVirt GUI didn't load in the Browser anymore. I tried to fix the issue by migrating to self-hosted engine, which did not work, so I ran engine restore and engine-setup in order to get back to the initial state. I am now able to login to the oVirt GUI again, but I am having the following problems: host1 is in status "Unassigned", and it has the SPM role. It cannot be set to maintenance mode, nor re-installed from GUI, but I am able to reboot the host from oVirt. All Storage Domains are inactive. (all NFS) In the /var/log/messages log, I can see the following message appearing frequently: "vdsm[5935]: ERROR ssl handshake: socket error, address: ::ffff:192.168.100.61" The cluster is down and no VM's can be run. I don't know how to fix either of the issues. Does anyone have an idea? I am appending a tar file containing log files to this email. http://gofile.me/5fp92/d7iGEqh3H <http://gofile.me/5fp92/d7iGEqh3H> Many thanks Toni

No option to remove OpenStack Glance storage domain.
by Gary Taylor 05 Apr '21

05 Apr '21

Hi, I was playing around a few months ago and added an ovirt-image-repository storage domain. There wasn't a real purpose for doing it, just trying to learn and play around. I tried to remove it earlier but couldn't figure out how because the Remove button is greyed out. I got busy and forgot about it. I am trying to clean it up now but the Remove button is still greyed out for that domain. How do I get rid of it now? It isn't being used. It's unattached. I'm the admin. https://imgur.com/KBKUu16.png oVirt Open Virtualization Manager Software Version:4.4.4.7-1.el8 Thank-you, Gary

Hosted-Engine vs Standalone Engine
by Ian Easter 05 Apr '21

05 Apr '21

Hello Folks, I have had to install a Hosted-Engine a few times in my environment. There have been some hardware issues and power issues that left the HE unrecoverable. In this situation, would the Standalone Engine install be more viable and less prone to become inoperable due to the previous issues? My assumption would be to have a head baremetal server run the Engine to control and maintain my blades. *Thank you,* *Ian*

Upgrade to release for oVirt 4.4.5 failing
by Gary Pedretty 05 Apr '21

05 Apr '21

Upgraded hosted-engine installation to latest version 4.4.5 today and engine will not come online. It starts and I can ssh and connect via cockpit, but it never passes liveliness check according to command line vm-status and Web portal for engine never loads. All processes appear to be working and nothing jumps out to me in the logs but ha agent keeps rebooting it on different hosts with the same result. 8 host in the cluster all are also updated to the latest updates across the board. This is Centos Stream 8 Ideas?

Locked disks
by Giulio Casella 01 Apr '21

01 Apr '21

Since yesterday I found a couple VMs with locked disk. I don't know the reason, I suspect some interaction made by our backup system (vprotect, snapshot based), despite it's working for more than a year. I'd give a chance to unlock_entity.sh script, but it reports: CAUTION, this operation may lead to data corruption and should be used with care. Please contact support prior to running this command Do you think I should trust? Is it safe? VMs are in production... My manager is 4.4.4.7-1.el8 (CentOS stream 8), hosts are oVirt Node 4.4.4 TIA, Giulio
