oVirt + Gluster
by TomK 23 Sep '19

Hey All, Seeing GlusterFS up to version 7, do any of the oVirt versions support anything higher then 3.X? Or is Gluster not the preferred distributed file system choice for oVirt? -- Thx, TK.

On the opposite - ovirt supports up to v6 of gluster and in cockpit, you can setup your hyperconverged setup (on gluster) abd your hosted engine ontop.

ifcfg-bond0 getting overwritten.
by TomK 22 Sep '19

Hey All, My ifcfg-bond0 is getting overwritten on reboot. Need to add a search string to the configuration. What's overwriting it and should I be trying to add a search string to another location? -- Thx, TK.

This depends if you use NetworkManager.service for other connections. If you don't use NetworkManager , then that's a working approach.

Linked Clones?
by marzoccafabio＠gmail.com 22 Sep '19

22 Sep '19

Hi, I am approaching and studying oVirt in order to propose the solution to a customer as a replacement for a commercial solution they have now. They only need Desktop virtualization. Sorry for the silly question, but I can't find a way to deploy a VM (template) to users as a "linked-clone", meaning that the users' image still refers to the original image but modification are written (and afterwards read) from a new location. This technique is called Copy-on-write. Can this be achieved with oVirt? Fabio

CentOS 7.7 has been released: note it's not supported for oVirt 4.2
by Sandro Bonazzola 19 Sep '19

19 Sep '19

CentOS 7.7 has been released this week. Please note that CentOS 7.7 is not supported for oVirt 4.2 and older releases. If you want to upgrade to CentOS 7.7 please upgrade to oVirt 4.3 too. If you don't plan to upgrade to oVirt 4.3 please be sure your yum repo files points to http://mirror.centos.org/centos/7.6.1810/ instead of http://mirror.centos.org/centos/7/. The http://mirror.centos.org/centos/7/ URL is now pointing to http://mirror.centos.org/centos/7.7.1908/ so yum upgrade will bring you 7.7 content which may break your 4.2 installation.

Re: Upgrade from 4.3.5 rc5 to 4.3.6 rc5 strange errors
by Strahil 19 Sep '19

Yeah, I've noticed I was searching for the wrong library (patching from phone seems to be not such a smart idea :) ) . Installing libibverbs fixed the issue, and a bug is opened so devs can find where the deps were missing. Did you notice this behaviour on your setup ?

Hi. I am using the https://github.com/oVirt/ovirt-engine-sdk/blob/master/sdk/examples/download… script to backup my vms. The problem is that always after the backup finishes, the snapshot is locked.
