Gluster release and oVirt 4.4
by Simon Coter 25 Jan '21

25 Jan '21

Hi, is there any plan to introduce Gluster-8 for hyper-converged architecture with oVirt 4.4 ? Just wondering because I can see Gluster-7 is declared EOL on Dec 11, 2020 (https://www.gluster.org/release-schedule/ <https://www.gluster.org/release-schedule/>) Thanks Simon

CentOS Stream support
by Michal Skrivanek 25 Jan '21

25 Jan '21

Hi all, we would like to ask about interest in community about oVirt moving to CentOS Stream. There were some requests before but it’s hard to see how many people would really like to see that. With CentOS releases lagging behind RHEL for months it’s interesting to consider moving to CentOS Stream as it is much more up to date and allows us to fix bugs faster, with less workarounds and overhead for maintaining old code. E.g. our current integration tests do not really pass on CentOS 8.1 and we can’t really do much about that other than wait for more up to date packages. It would also bring us closer to make oVirt run smoothly on RHEL as that is also much closer to Stream than it is to outdated CentOS. So..would you like us to support CentOS Stream? We don’t really have capacity to run 3 different platforms, would you still want oVirt to support CentOS Stream if it means “less support” for regular CentOS? There are some concerns about Stream being a bit less stable, do you share those concerns? Thank you for your comments, michal

ovirt node based on centos 8 stream
by Nathanaël Blanchet 25 Jan '21

25 Jan '21

Hi all, I project to upgrade from 4.3 to 4.4 hosts in the next few days, and I wonder if ovirt node based on centos 8.3 will be upgradable to ovirt node based on centos stream. If not, I will wait to upgrade directly to ovirt node centos stream based when available. -- Nathanaël Blanchet Supervision réseau SIRE 227 avenue Professeur-Jean-Louis-Viala 34193 MONTPELLIER CEDEX 5 Tél. 33 (0)4 67 54 84 55 Fax 33 (0)4 67 54 84 14 blanchet(a)abes.fr

Re: VM templates

First of all , verify the gluster volume options (gluster volume info <VOLNAME> ; gluster volume status <VOLNAME>).When you use HCI, ovirt sets up a lot of optimized options in order to gain the maximum of the Gluster storage.

HCI Deployment via Ansible
by penguin pages 25 Jan '21

25 Jan '21

I am trying to teach myself new and better means to deploy and control oVirt and HCI deployment. Does anyone have notes, experience and or examples.. website etc.. where someone managed deployment and admin of HCI deployment (CentOS + Cockpit + gluster + oVirt) and instead of using shell and manaual / gui deployment, did this "Infrastructure as code" Ex Step 1: 1) Foundation with kickstart. three nodes with "minimal install" all with ssh keyless password login for user "ansible" 2) Keys exchanged between nodes for keyless login for root and ansible user 3) Using ansible publish HCI deployment playbook. -> Define drive for each host to use -> Define name and host / ip of engine -> install HCI engine with gluster -> Add SSH keys for ansible and access so future oVirt interaction can be done via ansible I am just starting to research this.. but hoping others have blazed this path and I can leverage their process. Concerns: 1) How to get HCI to deploy only engine layer on (in my case... 512GB SSD .. with VDO and avoid destroying VMS not related to engine).. aka if I have to repair engine again will it keep nuking the volumes "data" and "vmstore" volumes which I think the HCI deployment wants to do if it has to redeploy fresh. 2) If above is always to be an issue .. can I make default VM deployment be a dedicated gluster volume (my case is 1TB SSD with VDO in each server) such that rebuild of engine layer can just slurp back in the VMs from that volume.

Performance issue to retrieve VM's after upgrading engine from 4.2 to 4.3
by Jonas Lindholm 25 Jan '21

25 Jan '21

This is a weird issue. Before upgrading it took 8-9 seconds to retrieve all VM's, 1230, using /ovirt-engine/api/vms URI. After the upgrade it now takes over 2 minutes. Query other items such as hosts, clusters, data centers etc is fast and the same speed as prior the upgrade from 4.2 to 4.3 I don't know if this is DB related or jboss related but any clue where to start to dig deeper is welcome. I also built a new VM and restored the DB's and ran engine-setup, but that new engine also gets more or less exactly the same response times for the VM's using the restAPI. I have another engine with same version 4.3.10.4-1, That only have 261 VMs but those are retrieved within 1-2 seconds only so I don't understand how that engine is so much faster than the one I upgraded. The UI also has the same long response times to show VM's from Compute -> Virtual Machines Any idea what could cause this?

ovirt-ha-agent
by Ariez Ahito 25 Jan '21

25 Jan '21

last dec i installed hosted-engine seems to be working, we can migrate the engine to different host. but we need to reinstall everything because of gluster additional configuration. so we did installed hosted-engine. but as per checking. we cannot migrate the engine to other hosts. and the ovirt-ha-agent and ovirt-ha-broker is status is inactive (dead) what are we missing?

VM templates
by Robert Tongue 25 Jan '21

25 Jan '21

Hello, Another weird issue over here. I have the latest oVirt running inside VMware Vcenter, as a proof of concept/testing platform. Things are working well finally, for the most part, however I am noticing strange behavior with templates, and deployed VMs from that template. Let me explain: I created a basic Ubuntu Server VM, captured that VM as a template, then deployed 4 VMs from that template. The deployment went fine; however I can only start 3 of the 4 VMs. If I shut one down one of the 3 that I started, I can then start the other one that refused to start, then the one I JUST shut down will then refuse to start. The error is: VM test3 is down with error. Exit message: Bad volume specification {'device': 'disk', 'type': 'disk', 'diskType': 'file', 'specParams': {}, 'alias': 'ua-2dc7fbff-da30-485d-891f-03a0ed60fd0a', 'address': {'bus': '0', 'controller': '0', 'unit': '0', 'type': 'drive', 'target': '0'}, 'domainID': '804c6a0c-b246-4ccc-b3ab-dd4ceb819cea', 'imageID': '2dc7fbff-da30-485d-891f-03a0ed60fd0a', 'poolID': '3208bbce-5e04-11eb-9313-00163e281c6d', 'volumeID': 'f514ab22-07ae-40e4-9146-1041d78553fd', 'path': '/rhev/data-center/3208bbce-5e04-11eb-9313-00163e281c6d/804c6a0c-b246-4ccc-b3ab-dd4ceb819cea/images/2dc7fbff-da30-485d-891f-03a0ed60fd0a/f514ab22-07ae-40e4-9146-1041d78553fd', 'discard': True, 'format': 'cow', 'propagateErrors': 'off', 'cache': 'none', 'iface': 'scsi', 'name': 'sda', 'bootOrder': '1', 'serial': '2dc7fbff-da30-485d-891f-03a0ed60fd0a', 'index': 0, 'reqsize': '0', 'truesize': '2882392576', 'apparentsize': '3435134976'}. The underlying storage is GlusterFS, self-managed outside of oVirt. I can provide any logs needed, please let me know which. Thanks in advance.
