Correction, the issue came back, but I fixed it again, the actual issue was multipathd. I had to set up device filters in /etc/multipath.conf blacklist { protocol "(scsi:adt|scsi:sbp)" devnode "^hd[a-z]" devnode "^sd[a-z]$" devnode "^sd[a-z]" devnode "^nvme0n1" devnode "^nvme0n1p$"blacklist { } Probably overkill, but it works. ________________________________ From: Robert Tongue <phunyguy(a)neverserio.us> Sent: Tuesday, January 26, 2021 2:24 PM To: users <users(a)ovirt.org> Subject: Re: VM templates I fixed my own issue, and for everyone else that may run into this, the issue was the fact that I created the first oVirt node VM inside VMware, and got it fully configured with all the software/disks/partitioning/settings, then cloned it to two more VMs. Then I ran the hosted-engine deployment and set up the cluster.

OVN and change of mgmt network
by Gianluca Cecchi 26 Jan '21

26 Jan '21

Hello, I previously had OVN running on engine (as OVN provider with northd and northbound and southbound DBs) and hosts (with OVN controller). After changing mgmt ip of hosts (engine has retained instead the same ip), I executed again on them the command: vdsm-tool ovn-config <ip_of_engine> <nel_local_ip_of_host> Now I think I have to clean up some things, eg: 1) On engine where I get these lines below systemctl status ovn-northd.service -l . . . Sep 29 14:41:42 ovmgr1 ovsdb-server[940]: ovs|00005|reconnect|ERR|tcp: 10.4.167.40:37272: no response to inactivity probe after 5 seconds, disconnecting Oct 03 11:52:00 ovmgr1 ovsdb-server[940]: ovs|00006|reconnect|ERR|tcp: 10.4.167.41:52078: no response to inactivity probe after 5 seconds, disconnecting The two IPs are the old ones of two hosts It seems that a restart of the services has fixed... Can anyone confirm if I have to do anything else? 2) On hosts (there are 3 hosts with OVN on ip 10.4.192.32/33/34) where I currently have this output [root@ov301 ~]# ovs-vsctl show 3a38c5bb-0abf-493d-a2e6-345af8aedfe3 Bridge br-int fail_mode: secure Port "ovn-1dce5b-0" Interface "ovn-1dce5b-0" type: geneve options: {csum="true", key=flow, remote_ip="10.4.192.32"} Port "ovn-ddecf0-0" Interface "ovn-ddecf0-0" type: geneve options: {csum="true", key=flow, remote_ip="10.4.192.33"} Port "ovn-fd413b-0" Interface "ovn-fd413b-0" type: geneve options: {csum="true", key=flow, remote_ip="10.4.168.74"} Port br-int Interface br-int type: internal ovs_version: "2.7.2" [root@ov301 ~]# The IPs of kind 10.4.192.x are ok. But there is a left-over of an old host I initially used for tests, corresponding to 10.4.168.74, that now doesn't exist anymore How can I clean records for 1) and 2)? Thanks, Gianluca

Replaced host but ovn complains of duplicate port
by Kevin Doyle 26 Jan '21

26 Jan '21

I had to rebuild a host. I first removed it from Ovirt then reinstalled the OS. I then used the same 192.xxx.xxx.207 IP as the old host. I then added it to Ovirt which seem to go OK. However I am seeing lots of ovn errors complaining that there was an existing port for the same IP Port ovn-47cc88-0 new port is ovn-af7f78-0 ovs-vsctl show 34c43e58-46f5-4217-8f2e-5801e1f2b9de Bridge br-int fail_mode: secure Port "ovn-24b972-0" Interface "ovn-24b972-0" type: geneve options: {csum="true", key=flow, remote_ip="192.xxx.xxx.204"} Port "ovn-ec1bbd-0" Interface "ovn-ec1bbd-0" type: geneve options: {csum="true", key=flow, remote_ip="192.xxx.xxx.201"} Port "ovn-47cc88-0" Interface "ovn-47cc88-0" type: geneve options: {csum="true", key=flow, remote_ip="192.xxx.xxx.207"} Port "ovn-d1e09d-0" Interface "ovn-d1e09d-0" type: geneve options: {csum="true", key=flow, remote_ip="192.xxx.xxx.203"} Port "ovn-f5ded7-0" Interface "ovn-f5ded7-0" type: geneve options: {csum="true", key=flow, remote_ip="192.xxx.xxx.202"} Port "ovn-1cb1b0-0" Interface "ovn-1cb1b0-0" type: geneve options: {csum="true", key=flow, remote_ip="192.xxx.xxx.206"} Port br-int Interface br-int type: internal Port "ovn-af7f78-0" Interface "ovn-af7f78-0" type: geneve options: {csum="true", key=flow, remote_ip="192.xxx.xxx.207"} error: "could not add network device ovn-af7f78-0 to ofproto (File exists)" ovs_version: "2.10.1" / var/log/ovs-vswitchd.log tunnel|WARN|ovn-af7f78-0: attempting to add tunnel port with same config as port 'ovn-47cc88-0' (::->192.xxx.xxx.207, key=flow, legacy_l2, dp port=2) 2021-01-26T18:03:38.128Z|69740|ofproto|WARN|br-int: could not add port ovn-af7f78-0 (File exists) 2021-01-26T18:03:38.128Z|69741|bridge|WARN|could not add network device ovn-af7f78-0 to ofproto (File exists) /var/log/messages Jan 26 18:03:37 xxxx05 kernel: device genev_sys_6081 entered promiscuous mode Jan 26 18:03:37 xxxx05 kernel: i40e 0000:3d:00.0 eno3: UDP port 6081 was not found, not deleting Jan 26 18:03:37 xxxx05 kernel: i40e 0000:3d:00.1 eno4: UDP port 6081 was not found, not deleting Jan 26 18:03:37 xxxx05 kernel: i40e 0000:3d:00.2 eno5: UDP port 6081 was not found, not deleting Jan 26 18:03:37 xxxx05 kernel: i40e 0000:3d:00.3 eno6: UDP port 6081 was not found, not deleting I can bring the host 192.xxx.xxx.107 down and the errors stop on the other hosts but ovn still has a port defined for 192.xxx.xxx.207 The question I have is how do I delete the old port definition ?

Is there a plan for ovirt 4.5 and furture versions?
by Flashbang 26 Jan '21

26 Jan '21

We know that at this time of the past years, the beta version of the new ovirt version has been released, but this year there is still no news about ovirt 4.5. Red Hat has announced last year that ovirt and openstack will be integrated with openshift in the future. So, will there be ovirt 4.5 or ovirt 4.6? Is it worth building a new virtualization platform based on ovirt? https://www.redhat.com/es/blog/future-open-virtualization-here

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

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.

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

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

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.

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?

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.

split brain scenario?
by Henry lol 24 Jan '21

24 Jan '21

Hi, according to HA VM documentation, a paused VM may be started on another host and later resumed on the original host. - https://www.ovirt.org/develop/ha-vms.html here, I'm assuming the HA VM was paused due to I/O error. but I'm wondering how it can happen because I guess the HA VM will be restarted on another host only after it's completely killed from the original host. can you give the split brain scenario?
