Is there a way hot to reserve MAC address ?
by Michal Mocnak 26 Jan '21

26 Jan '21

Hey Guys, is there a way how to reserve MAC address for VMs created from the pool ? I have a workaround via ansible playbook which works fine but I am wondering if there is any other solution how to achieve this. And btw if i use predefined instance type other than Custom there are no network interfaces in newly created machines. Is it right behavior ? Thank you so much !! Cheers -m

'python-nftables' failed. There is a big problem with Firewalld and openvswitch on Centos 8.3
by Сергей Шопин 26 Jan '21

26 Jan '21

I have deployed a new cluster on versions: 3 Hosts: Centos 8.3 and last update Ovirt: 4.4.4.7-1.el8 Cluster properties: switch - OVS; Firewall - Firewalld During the initial deployment of the host in such a cluster, everything is successfully installed, all virtual networks and bridges are created, and the host is activated. But after that, Firewalld does not work correctly, for example, when executing the command firewall-cmd --reload Issued by: Error: COMMAND_FAILED: 'python-nftables' failed: JSON blob: {"nftables": [{"metainfo": {"json_schema_version": 1}}, {"add": {"table": {"family": "inet", "name": "firewalld_policy_drop"}}}, {"add": {"chain": {"family": "inet", "table": "firewalld_policy_drop", "name": "filter_input", "type": "filter", "hook": "input", "prio": 9, "policy": "drop"}}}, {"add": {"chain": {"family": "inet", "table": "firewalld_policy_drop", "name": "filter_forward", "type": "filter", "hook": "forward", "prio": 9, "policy": "drop"}}}, {"add": {"chain": {"family": "inet", "table": "firewalld_policy_drop", "name": "filter_output", "type": "filter", "hook": "output", "prio": 9, "policy": "drop"}}}, {"add": {"rule": {"family": "inet", "table": "firewalld_policy_drop", "chain": "filter_input", "expr": [{"match": {"left": {"ct": {"key": "state"}}, "op": "in", "right": {"set": ["established", "related"]}}}, {"accept": null}]}}}, {"add": {"rule": {"family": "inet", "table": "firewalld_policy_drop", "chain": "filter_forward", "expr": [{"match": {"left": {"ct": {"key": "state"}}, "op": "in", "right": {"set": ["established", "related"]}}}, {"accept": null}]}}}, {"add": {"rule": {"family": "inet", "table": "firewalld_policy_drop", "chain": "filter_output", "expr": [{"match": {"left": {"ct": {"key": "state"}}, "op": "in", "right": {"set": ["established", "related"]}}}, {"accept": null}]}}}]} Now all ansible-playbook ovirt starts to execute uncorrectly For example this error is thrown every time I try to reinstall the host: VDSM SMnode02 command CollectVdsNetworkDataAfterInstallationVDS failed: Internal JSON-RPC error: {'reason': ’management’} I understand that ovirt correctly executes scripts, and this problem is related to the applications Firewalld, openvswitch, NetworkManager. Is there some workaround so that at least ovirt can re-install hosts?

Unable to ping host from VM's or VM's from host
by David Johnson 25 Jan '21

25 Jan '21

I have a brand new Ovirt 4.5 cluster on centos 8 and brand new hardware. I have a set of VM's, some of whom I have been able to connect to in the past, others that I have never been able to connect to other than with the SPICE console ui. Right now, I am unable to connect from outside my cluster to any of the VPN's other than through the SPICE console. Host IP: 192.168.2.188 Physical Address Example VM IP: 10.21.10.101 with vLAN tag Works: * I can connect between vm's on the same subnet on the same VM. When logged into 10.21.10.101 I can ping 10.21.10.100 Doesn't work: * I cannot connect from VM's to the host. * I cannot connect from the host to VM's PING 10.21.10.100 (10.21.10.100) 56(84) bytes of data. From <<internet gateway>> icmp_seq=1 Destination Host Unreachable * I cannot connect from the VM's to the internet gateway * I cannot connect to the VM's from other systems on the physical network "Destination Host Unreachable" To me it looks like the virtual bridge is misconfigured, but I can't figure out how to reconfigure it. Any assistance would be greatly appreciated. Regards, David Johnson

oVirt initramfs regeneration
by Robert Tongue 25 Jan '21

25 Jan '21

Is it possible to force an initramfs regeneration in oVirt Node 4.4.4? I am doing some advanced partitioning and cannot seem to figure out how to properly do that if it's even possible. Thanks. -phunyguy

Geographically-distrbuted Ovirt Cluster?
by Derek Atkins 25 Jan '21

25 Jan '21

Hi, Right now I run a 1-server hyperconverged hosted-engine deployment. Other than requiring systemwide downtime to perform host maintenance, it has worked fairly well for me over the past few years. However, after a couple power and upstream-network outages, there have been questions about the ability to "distribute the load", so to speak. Considering what our workload is (main git repo, wiki, email list + archives, etc), it can't easily be distributed by a periodic resync and DNS round robin like a static web site. To solve this distribution problem I was wondering if there might be some way to deploy a handful of physical servers in different geographic locations that work together to create an HE environment for guest VMs? My initial fear would be that it would require dedicated 1Gb (or higher) between the sites to move data? Let's say we do NOT have that level of connectivity. I saw something about geographic replication in Gluster? But that would seem to be more about replicating a local cluster to a remote cluster? I suspect the answer is: no, a cluster must all be physically co-located. But I figured I would ask the experts. Thanks all for your insights. -derek -- Derek Atkins 617-623-3745 derek(a)ihtfp.com www.ihtfp.com Computer and Internet Security Consultant

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

25 Jan '21

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.
