Alternative Perspective - Re: oVirt alternatives
by David White 07 Feb '22

07 Feb '22

At the risk of sounding like a Red Hat or IBM fanboy, I have decided to give Red Hat the benefit of the doubt here, and to not make any decisions about switching off of oVirt until and unless an official announcement is made. In the meantime, I know that I need to move off of Gluster (and I made that decision before the Gluster announcement), and I would need storage with any other solution anyway, so that's where I'm going to focus my own efforts. In the meantime, while I realize that the optics of a company like IBM / Red Hat shutting a project like oVirt down looks bad to the FOSS community, I'm going to push back a little bit. We have had access to a FOSS application that obviously works for a lot of people. No company is required to provide their services for free, and likewise, I'm of the opinion that one needs to be willing to pay (or contribute in some way) for a quality product service. It reminds me of the mantra: "Fast, Cheap, Free - pick two". So here's an alternative perspective: What can the community contribute and do in order to keep the project going? Anyone could fork it, rebrand it, and run with it. I claim to be a software developer, and the uplink in my datacenter is only 100mbps right now (of course I can increase it when needed), so I doubt I could provide much value in terms of hosting or coding. But I do know security. I'm a Linux systems engineer with over 10 years of experience. I know website content management systems. And people have told me that I'm good at documentation. So I think I have a lot of skill sets that I could "offer" (albeit I don't have much time, and as we all know, time is money. I've been dealing with a serious personal matter since beginning of December, and I'm effectively an acting single parent at the moment). I'll end this the way I started: I'm going to wait to see what happens before I personally make any decisions to change my entire underlying virtualization infrastructure. In the meantime, I'll continue to work on what I can control - the underlying storage. And if oVirt does shutdown in the future, I'd love to have a conversation with anyone interested in helping out to fork the project and keep it running. Sent with ProtonMail Secure Email.

Importing export storage domain after redeploy failing, stating export domain still connected.
by Gilboa Davara 07 Feb '22

07 Feb '22

Hello all, I'm rebuilding one of my gluster clusters after it blew up following an unfortunate expired certificate issue. After I finally remembered to downgrade qemu (grrrr...) and started importing the hold gluster storage domains, one of the export domains failed to import due to "connected to another domain" issue. How can I force detach it from the previous cluster? (I remember something about deleting the lease file - but I'm too brain dead to find it in DDG...).

how to search event not matching a user
by Gianluca Cecchi 07 Feb '22

07 Feb '22

Hello, every event in Advanced view has a field "User". I'm trying to compose a search in web admin of events with user different from myuser@internal It seems I'm not able to get what I want. I also tried to base attempts on an old 2019 thread (on 4.3.6) where this queries worked: Disks: name=engine* or name=host* Disks: alias=engine* or alias=host* but now on 4.4.8 gives nothing even if matched. Any hint and also documentation reference about the correct syntax to use in 4.4.x? Thanks, Gianluca

What happened to oVirt engine-setup?
by Richard W.M. Jones 07 Feb '22

07 Feb '22

A while back I had oVirt 4.4.7 installed which I used for testing. For some reason that installation has died in some way, so I'm trying to install a fresh new oVirt 4.4.10. Last time I installed ovirt, it was very easy - I provisioned a couple of machines, ran engine-setup in one, answered a few questions and after a few minutes the engine was installed. Somehow this has changed and now it's really far more complicated, involving some ansible things and wanting to create VMs and ssh everywhere. Can I go back to the old/easy way of installing oVirt engine? And if so, what happened to the instructions for that?

VM Image is Locked after cleaning up of problematic snapshot.
by Muhammad Aidilfitri Bin Saleh 06 Feb '22

06 Feb '22

Hello Everyone, I requires your input as the VM that is currently Hosted on Ovirt 4.4.4.5 is showing a locked Icon in the status column. I am unable to perform any actions on this particular VM as it shows that the "Snapshot is currently being created for VM <VMName> There was a failed snapshot attempt executed earlier but I have gone through the steps to identified and unlock the said images and snapshot using the build tools /usr/share/ovirt-engine/setup/dbutils. I even went into the DB to identified the failed snapshot but still no luck. I have restarted the ovirt-engine service and also the Standalone VM hosting this Ovirt-Engine but still not able to release the VM. I have also performed the ovirt-setup but still no luck on this portion. Any assistance is appreciated.

Hosted Engine down and not visible on any host
by milan.mithbaokar＠gmail.com 04 Feb '22

04 Feb '22

Hi, We have a 4 node ovirt cluster running at 4.4.1.5. We are running it on iSCSI shared Storage. The hosted engine is running on its separate iSCSI shared storage. Hosted Engine went down all of a sudden and no where to be found on any of the nodes when I do virsh list --all All other VM's are showed in the list but cannot see the hosted engine? when we try to bring hosted engine up using "hosted-engine --vm-start" it errors out with message "vm does not exist". The shared iscsi storage ip on which the HE vm was running is pingable, but when we perform "hosted-engine --connect-storage" we are getting request timeouts after 60 seconds. Any ideas to restore back the hosted engine and the cluster highly appreciated.

Installing a windows vm from importing an OVA Template
by moizr＠emiratesnbd.com 04 Feb '22

04 Feb '22

We are trying to create a windows vm on OLVM/OVirt. Below are the steps we followed - Exported an OVF of a plain windows vm from vmware. - Imported it as an OVA to OLVM - Start the VM after change OS type to Windows 2016. As soon as we select Windows 2016 the server doesnt start but works when we make it as other OS. We want to automated provisioning and setup of the vm through sysprep but the vm doesnt start once we select OS as Windows on the template or any vm created out of that template.

Unclear how to add local (POSIX) storage
by Richard W.M. Jones 04 Feb '22

04 Feb '22

I'm following the instructions here: https://access.redhat.com/documentation/en-us/red_hat_virtualization/4.2/ht… I've also added an extra virtual disk to my host node which appears as /dev/sdb. Although the disk is partitioned, /dev/sdb1 is not created. Is udev broken in oVirt node? I cannot see anywhere in the dialog where you specify the name of the device (eg. "/dev/sdb1"). So how's it supposed to work? It doesn't work, giving an information-free error message: Error while executing action Add Storage Connection: Problem while trying to mount target Rich. -- Richard Jones, Virtualization Group, Red Hat http://people.redhat.com/~rjones Read my programming and virtualization blog: http://rwmj.wordpress.com libguestfs lets you edit virtual machines.

Erasure Coding Storage Support
by alishirv＠pm.me 04 Feb '22

04 Feb '22

Hello everyone, I'm new to oVirt. I want to set up a cost-efficient and fault-tolerant virtualization environment. Our VMs have low to medium IOPS, 70% of VMs have low IOPS and about 30% of them require about 5K IOPS. All the disks are NVMe. I found that the most cost-efficient storage plan in the current oVirt is a two-way replica with an arbiter and its storage overhead is more than 100%. As far as I know, we can use erasure coding with less storage overhead. Is there any plan to support erasure coding in oVirt? Would you even recommend erasure coding for VM workloads? Best regards, Ali
