24 Feb '21

Hi, I've one server ovirt-engine. I've trois nodes glusterfs on this ovirt-engine. Ex: ovirt-engine : ovirt-node1, ovirt-node2 and ovirt-node3. Now, I want add ovirt-node4. I tried with "Deploying oVirt and Gluster Hyperconverged". But it propose only trois nodes. Could you help me, please ? Best regard, Anne Garcia

oVirt Ansible cluster deployment
by Jeremey Wise 24 Feb '21

24 Feb '21

I am trying to eat own dog food. Infrastructure as code... So.. I have taken three physical servers. Setup all the base packages, set NICs, NTP, DNS, collected disk UUIDs etc.. The servers are prepped. And one server has cockpit and ovirt-engine installed... and service started. ############################# --- # This task takes nodes prepaired and deploys cockpit, ovirt deployment and scripts cluster initilization. ONLY RUN THIS ON FIRST NODE OF CLUSTER # v0.001 20210222 # file: /roles/task_hci_setup.yml # Documentation # Overview: https://www.ovirt.org/documentation/gluster-hyperconverged/chap-Deploying_H… - name: Check if rpm ovirt-release44 is already installed yum: list: ovirt-release44 register: yum_list - name: Conditionally do next thing debug: msg: "ovirt-release44 Not installed" when: yum_list.results | selectattr("yumstate", "match", "installed") | list | length == 0 # Add oVirt Repo manual. - name: Download oVirt Repo RPM get_url: url: https://resources.ovirt.org/pub/yum-repo/ovirt-release44.rpm dest: ~/ovirt-release44.rpm mode: '0440' when: yum_list.results | selectattr("yumstate", "match", "installed") | list | length == 0 - name: Install Python3 as this is needed for oVirt. yum: name: - python3 state: latest become: true - name: For some reason install of oVirt Repo fails as package so have to run as shell command: "rpm -ivh ~/ovirt-release44.rpm" when: yum_list.results | selectattr("yumstate", "match", "installed") | list | length == 0 - name: With new oVirt repo.. install rest of HCI dependancies yum: name: - cockpit-ovirt-dashboard - vdsm-gluster - ovirt-host - ovirt-ansible-roles - ovirt-ansible-infra state: latest become: true # Set variable for first node in cluster list to set as ignition master - name: Only on first node thor deploy ovirt-engine-appliance yum: name: - ovirt-engine-appliance state: latest become: true when: "'{{ hci_ignition_node }}' in inventory_hostname" # on local ansible host install galaxy modules # Broken: I need a means to check if installed.

Which is ... what I would do in the wizard... ... but "step away from the mouse". # Ansible section: from bastion node (laptop windows 10 WSL with ansible and galaxy installed # 1) build playbook from my site variables... based on some ovirt master sharing template of what that UI builds # 2) push the playbook that installs ansible on the first node. Install ansible as a first node... Run ansible playbook from customized template file # 3) Create vlans. # 4) Setup new VM gluster shared volume from three other disk # 5) Push a template VM into cluster, attached to new VLAN and attached to new volume #6) Deploy VM from this template #7) Drink a cold beer ############################### Question: 1) Can you do ansible deployment from "bastion host" or does the ansible have to run on the node that is installed with the "ovirt-engine". If so.. how do you collect feedback etc.. 2) I assume there is a template. Maybe it is published but I could not find it. That I replace (or match) variables of my site that fill in that file. 3) I installed galaxy oVirt.ovirt-ansible-roles but.. how do I know it is deployed on my bastion host? I poked around in the ansible folder.. not seeing anything. And I assume this only is of help POST the above seven steps being done. But maybe this has deployment components and I am missing documents. Thanks, -- p <jeremey.wise(a)gmail.com>enguinpages

Did you install ovirt-guest-tools on the VM from the iso available at your engine vm package? Did the related service start in WIndows 10 OS? You didn't reply why you are forced to use so an "old" oVirt version: it is not old in absolute, but oVirt is rapidly evolving and you should stay at maximum behind one version. So if the latest is 4.3, stay no behind 4.2. Now, with 4.4 out since many months, stay no behind 4.3 at least... This way you get more correct help because more guys are on latest versions, that got many enhancements and many bug fixes (eg with snapshot management, illegal disks state some time, and so on) Gianluca

Invalid status on Data Center Default. Setting status to Non Responsive.
by Jelte Veldstra | Order2Cash 23 Feb '21

23 Feb '21

All, We have built a new oVirt cluster from scratch. We used the 4.4.4 installer released in December 2020. When deploying the engine we had the wizard create a Gluster volume for the engine on three hosts. All went well and the cluster is starting to take shape. When starting the engine we do see the following error each time the engine is started in /var/log/ovirt-engine/engine.log: 2021-02-23 08:06:09,208+01 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (EE-ManagedScheduledExecutorService-engineScheduledThreadPool-Thread-33) [4293beae] EVENT_ID: SYSTEM_CHANGE_STORAGE_POOL_STATUS_PROBLEMATIC(980), Invalid status on Data Center Default. Setting status to Non Responsive. Also when navigating in the engine web-ui to Compute -> Data Centers -> Default and check the events an event of id 980 is shown with the message: “Invalid status on Data Center Default. Setting status to Non Responsive.”. The date/time matches when the error is shown in the engine log. The datacenter overview does not show any warnings or errors and lists the Default datacenter as status Up. An interesting observation is that the cluster overview does have a status column on the far left, but the status is not mentioned. The field underneath the status heading is empty. Could that be the unknown status that the data center refers to? How could we investigate this further? The storage volumes do not show any issues and the cluster seems to function okay (it has not been used a lot yet as it has been built yesterday/today), but the error message does sound like something we need to get out of the way before we put the actual workload on it. Regards, Jelte

Hi Joseph, Somehow I missed your email. I am thinking in similar direction, but in all honesty, it’s takes bit of effort to accept that we need complete platform deployment from 4.3 to 4.4, considering EL 8 is required, to have this fixed. Anyway, let’s try re-deploying engine with current platform version in testing env, take our notes and share them. This is actually nice, team work. 😊 For now, in production, I am going to increase the RAM and CPU, and if reboot is required, just do it again. Too many CI/CD deployment failures, to leave the engine process fighting for resources. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

There are different parameters around memory - are you sure you change the correct one(s)? Also adding Arik. Arik - please see the history of this thread. It might be an issue in the engine, or in hosted-engine HA, or both - not sure. > But before I do that, we are currently on 4.3.8.2 version – is this by any change fixed by latest 4.3 version? No idea. 4.3 is past EOL now. I suggest to try latest 4.4, and if it reproduces, file a bug and attach all relevant logs (including engine, vdsm, hosted-engine-ha).

Re: oVirt Engine increase RAM and CPU

Hi Marko, I have also had this problem on an oVirt 4.3 install - I could never fix it and have not tried to upgrade to 4.4 yet - my workaround for now (as you have deduced) is to just 'up' it while running so its hotswapped in - annoying, but I think the best way around this without upgrade would be to re-deploy the hosted engine defining the new resources using an engine-backup - but again this is just as scary as in-place upgrade lest you lock yourself out from your other running VMs in a production environment. I plan to do it - I just need some time to set it up in a lab so I know what to expect.

Initially, I made the change via Portal, updating defined memory of HE from 16384 to 32768. The change is instantly visible on VM when I execute free -m , but in the VM info it still says 16384. I waited almost 4hours and this value did not get updated. Tried shutdown, remove GM, allow the HA to start the VM, it booted with 16384 allocated. Than I did it again, and tried with Update OVF from storage domain where the HE disk is, same, no change. Tried, updating memory again, migrating to another HA host – Update OVF , same thing, after reboot, the memory is back to 16384. Can somebody give me an advice where to look further? Again, making the change in memory amount is instant on the VM, but after reboot, its back to 16384. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

oVirt Node install with Foreman VG issue
by simon＠justconnect.ie 22 Feb '21

22 Feb '21

Hi All, I have a server with a RAID1 disk for sda and RAID 5 disk for sdb. Following default install, prior to Cockpit Gluster and Engine wizards there is only a single Volume Group which doesn’t allow me to continue. If I manually configure the install and deselect sdb it gives other issues with multipath but at least I can resolve those. Is there a specific kickstart confuguration that should be used? Kind Regards Shimme

Mem guaranteed updates, CPU cores updates instantly and perist after reboot But defined memory is “stuck” on 16384 after reboot. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

Initially, I made the change via Portal, updating defined memory of HE from 16384 to 32768. The change is instantly visible on VM when I execute free -m , but in the VM info it still says 16384. I waited almost 4hours and this value did not get updated. Tried shutdown, remove GM, allow the HA to start the VM, it booted with 16384 allocated. Than I did it again, and tried with Update OVF from storage domain where the HE disk is, same, no change. Tried, updating memory again, migrating to another HA host – Update OVF , same thing, after reboot, the memory is back to 16384. Can somebody give me an advice where to look further? Again, making the change in memory amount is instant on the VM, but after reboot, its back to 16384. ----- kind regards/met vriendelijke groeten Marko Vrgotic Sr. System Engineer @ System Administration ActiveVideo o: +31 (35) 6774131 m: +31 (65) 5734174 e: m.vrgotic(a)activevideo.com<mailto:m.vrgotic@activevideo.com> w: www.activevideo.com<http://www.activevideo.com> ActiveVideo Networks BV.

[ANN] oVirt 4.4.5 Sixth Release Candidate is now available for testing
by Lev Veyde 22 Feb '21

22 Feb '21

oVirt 4.4.5 Sixth Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.5 Sixth Release Candidate for testing, as of February 18th, 2021. This update is the fifth in a series of stabilization updates to the 4.4 series. How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1 Note: Upgrading from 4.4.2 GA or later should not require re-doing these steps, if already performed while upgrading from 4.4.1 to 4.4.2 GA. These are only required to be done once. Due to Bug 1837864 <https://bugzilla.redhat.com/show_bug.cgi?id=1837864> - Host enter emergency mode after upgrading to latest build If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.5 you may get your host entering emergency mode. In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts: 1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted). 2. Reboot. 3. Upgrade to 4.4.5 (redeploy in case of already being on 4.4.5). 4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place. 5. Only if not using oVirt Node: - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration 6. Reboot. Documentation - If you want to try oVirt as quickly as possible, follow the instructions on the Download <https://ovirt.org/download/> page. - For complete installation, administration, and usage instructions, see the oVirt Documentation <https://ovirt.org/documentation/>. - For upgrading from a previous version, see the oVirt Upgrade Guide <https://ovirt.org/documentation/upgrade_guide/>. - For a general overview of oVirt, see About oVirt <https://ovirt.org/community/about.html>. Important notes before you try it Please note this is a pre-release build. The oVirt Project makes no guarantees as to its suitability or usefulness. This pre-release must not be used in production. Installation instructions For installation instructions and additional information please refer to: https://ovirt.org/documentation/ This release is available now on x86_64 architecture for: * Red Hat Enterprise Linux 8.3 or newer * CentOS Linux (or similar) 8.3 or newer This release supports Hypervisor Hosts on x86_64 and ppc64le architectures for: * Red Hat Enterprise Linux 8.3 or newer * CentOS Linux (or similar) 8.3 or newer * oVirt Node 4.4 based on CentOS Linux 8.3 (available for x86_64 only) See the release notes [1] for installation instructions and a list of new features and bugs fixed. Notes: - oVirt Appliance is already available for CentOS Linux 8 - oVirt Node NG is already available for CentOS Linux 8 - We found a few issues while testing on CentOS Stream so we are still basing oVirt 4.4.5 Node and Appliance on CentOS Linux. Additional Resources: * Read more about the oVirt 4.4.5 release highlights: http://www.ovirt.org/release/4.4.5/ * Get more oVirt project updates on Twitter: https://twitter.com/ovirt * Check out the latest project news on the oVirt blog: http://www.ovirt.org/blog/ [1] http://www.ovirt.org/release/4.4.5/ [2] http://resources.ovirt.org/pub/ovirt-4.4-pre/iso/ -- Lev Veyde Senior Software Engineer, RHCE | RHCVA | MCITP Red Hat Israel <https://www.redhat.com> lev(a)redhat.com | lveyde(a)redhat.com <https://red.ht/sig> TRIED.

Please note that I do not have any experience with this whatsoever. Also for the further replies below. Just guessing. I suggest to try first on a test system if it's about a production/critical system. I guess that it will mark the VM as requiring a reboot for changes to take effect, and that they'll actually be applied only on hard-reboot (meaning, not just running 'reboot' from inside). So yes, I guess the process should be: 1. Edit as needed 2. Perhaps wait a bit or something like that to make sure changes reached OVF_STORE on the shared storage. No idea how. Perhaps we log enough about this to existing logs, or perhaps you can dump the conf to verify manually. 2. Set global maint, shutdown, clear global maint (and either immediately start the vm or let ha-agent do this for you). > > > > For the HEAP changes, I have been doing that lot on the Atlassian instances, just not sure how oVirt-engine is going to react and if there are any guidelines I should stick to in ovirt case. I have no idea other than the bugs I was personally involved with (which you can find in bugzilla). Perhaps RHV or oVirt docs have some guidelines, didn't check. If not, then I suppose the guidelines are "Use the defaults and follow recommendations", which mean: 1. Allocate 16GB RAM for the HE VM. Perhaps we even recommend more than that for larger setups, not sure. 2. engine-setup then sets both min and max to 4GB (=25% of RAM). If you do want to play with this, you should of course test thoroughly and carefully :-).

Re: oVirt Engine increase RAM and CPU
by Vrgotic, Marko 22 Feb '21

22 Feb '21

Hi Didi, Just to be sure, considering its an HA instance, I need to set to maintenance=global and execute these changes – CPU increase will most likely require reboot? For the HEAP changes, I have been doing that lot on the Atlassian instances, just not sure how oVirt-engine is going to react and if there are any guidelines I should stick to in ovirt case. I.e. What if I set min and max to same value? Is it going to be “ok” if I assign more than half of system RAM to the JAVA?

You can control the values passed as -Xms and -Xmx using the config values ENGINE_HEAP_MIN and ENGINE_HEAP_MAX. They are set by engine-setup on initial setup but not changed later. It writes /etc/ovirt-engine/engine.conf.d/10-setup-java.conf . It's probably safer to create your own file for overriding, e.g. 99-my-setup-java.conf or something.

ovirt-vmconsole (serial console) dimensions and word wrap
by Kurt Myers 22 Feb '21

22 Feb '21

I frequently use the ovirt-vmconsole (serial console) to interact with my VMs. Is there a way to have ovirt-console recognize the terminal size automatically rather than defaulting to the standard 80 columns by 25 rows? If not, can the column/row size be adjusted globally (so the dimensions can be set once but persist for all console connected VMs)? Also, is there a way to enable word-wrap in the ovirt-vmconsole? Thanks! -Kurt-

Cannot startVM due to iso permission issue

Hi I have a brand new installation and I am trying to create a new VM, I have the Linux ISO uploaded to a NFS ISO Storage Domain but the VM refuses to start, I observe following error: *unable to open /rhev/data-center/mnt/LTST-VIRTMAN01:_ovirt_iso/a284c684-bfa2-49a1-b419-e81001b6196e/images/11111111-1111-1111-1111-111111111111/V1003434-01.iso: Permission denied* have tried to disable selinux just in case but without success. Any clues? Thanks

4.3 -> 4.4 upgrade question
by KSNull Zero 21 Feb '21

21 Feb '21

Hello! We have only one 4.3 cluster and try to upgrade it to 4.4. I believe that engine-setup change the Cluster Setting "Default Network Provider" to "ovirt-provider-ovn" during upgrade procedure. So then we add freshly reinstalled RH8 host back to this cluster the oVirt tries to configure OVN on that host. But we don't want to use OVN. Is it safe to change this setting back to "No Default Provider" and continue hosts upgrade process ? Thank you.

Rebooting VM with mdev device reboots VM AND the host!
by paul.chapman＠farmgroup.tv 21 Feb '21

21 Feb '21

Hi I'm a new to Ovirt so please forgive any gaping hole in my knowledge. I have a self hosted engine set up with two hosts. Centos 8.3, Ovirt 4.4, (cluster set to 4.5 because it told me to). I have Nvidia Tesla T4 cards in both hosts with Nvidia driver 450.102. I have Win10 VMs on one host and the HE on another. The problem I have is that when you reboot the Win10 VM it also reboots the host it's sat on. I have 'intel_iommu=on' in my grub file and both hosts pass virt-host-validate. This set up was working fine on Centos 7 with Ovirt 4.3 so I'm at a bit of a loss to know what's going on. I'll post up the logs if anyone can let me know which ones they think would be relevant. Thanks in advance, Paul.

hosted-engine --vm-status returns "vm not running on this host" on all hosts
by paul.chapman＠farmgroup.tv 21 Feb '21

21 Feb '21

I have tried to upgrade from 4.3 to 4.4 in a self hosted environment and I now have multiple problems. One of which is that neither of my two hosts think they are running the hosted engine. What could cause this?

Changing the bridge for ovirt hosted engine
by Jordan Conway 21 Feb '21

21 Feb '21

Hello, I'd like to move my ovirt hosted engine deploy to a different cluster, but the problem that I'm faced with is that my hosted engine bridge runs on "ovirtmgmt" but the cluster I'd like to move it to the default vm network is "ovirtmgmt_vlan" Is there a process in which I could shutdown my hosted vm, edit it's network then bring it back up on the new cluster? I have already tried redeploying the new cluster with "deploy hosted engine" on it, but when I try to start the engine on a host in the new cluster it fails because it can't find the ovirtmgmt bridge. Thank you, Jordan Conway

oVirt Engine increase RAM and CPU
by Vrgotic, Marko 19 Feb '21

19 Feb '21

Hi oVirt, What is the cleanest way to increase the memory and cpu for SHE engine? We have the Engine running on top of three HA hosts, so I guess the specs need to be change on all three, while engine is down. Is it done by editing the VM libvirt conf file or some other way? Where do I allocate more RAM to JAVA for oVirt? We are currently running 4.3.8 version.

VXLAN
by Daniel Menzel 19 Feb '21

19 Feb '21

Hi, currently we're evaluation the usage of VXLAN in oVirt - and strangely enough we don't find anything in the manual. Has this been implemented, yet? Or are we just blind because it is hidden somewhere in the tons of features of /ovn/?
