Single Node Hyperconverged - Failing Gluster Setup
by jhamiltonactually＠gmail.com 10 Feb '21

10 Feb '21

Ovirt newbie here - using v 4.4.4 Have been trying for days to get this installed on my HP DL380p G6. I have 2 disk 170GB Raid 0 for OS and 6 x 330GB disk Raid 5 for Gluster. DNS all set up (that took some working out), but I just can't fathom out whats (not) happening here. Block size is returned as 512. I've had some help on Reddit where I've been told that Ovirt is seeing my single local disk ass an multipath device, which it is not/??! I think I removed the flag, but it still fails here. So, Gluster install fails quite early through, though it carries on creating all the volumes (with default settings) but then gives me the 'Deployment Failed' message :( Here is where it fails.... Any help gratefully received!

HostedEngine VM Paused after power failure
by Ian Easter 10 Feb '21

10 Feb '21

Hello Users, We have an oVirt (4.4) environment that had 2 hosts in the cluster. We suffered from a power failure that caused the servers to be offline for some time. Once restored, one of the hosts from the cluster lost its OS raid and is not accessible. The other server has the HostedEngine vm on it but in a paused state. I have tried to manually start the vm with the hosted-engine CLI tool but it indicates that HostedEngine is running on another host. Is there any manual intervention I can accomplish here to start the HostedEngine on the second, active host server? *Thank you,* *Ian Easter* *DevOps Engineer* *TelVue Support* https://www.telvue.com/support/

Random Crash
by francesco＠shellrent.com 09 Feb '21

09 Feb '21

Hi all, I'm experiencing random reboot on several oVirt nodes (CentOS 7/8, oVirt 4.3/4.4 as well). Sometimes it happens three times in a day, and the more hosts I'm adding to my pool, the more I noticing. The logs are not helpful: it's like a brute poweroff cause there are no entries at all in the messages, vdsm, secure (I looked all over the logs) from the last "normal" entry (user logged in/off, normal vdsm log ecc.) until the first entry of the boot. kdump is enabled and /var/crash is empty. I used to run Xen on the servers of the same provider and I didn't have all of these frequent reboots, that's why I'm not sure it is a hardware related issue. Any advice on what enables for getting more info about this crash? Thank you for your time, Francesco

09 Feb '21

Hi oVirt Users, I am trying to test some vfio related stuff on oVirt Node NG 4.4.4 based host. What would be the easiest way to have a 5.x kernel on this node? I don't mind compiling if it needs to. Cheers, Shantur

The he_fqdn proposed for the engine VM resolves on this host - error?
by lejeczek 07 Feb '21

07 Feb '21

hi chaps, a newcomer here. I use cockpit to deploy hosted engine and I get this error/warning message: "The he_fqdn proposed for the engine VM resolves on this host" I should mention that if I remove the IP to which FQDN resolves off that iface(plain eth no vlans) then I get this: [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "The selected network interface is not valid"} All these errors seem bit too cryptic to me. Could you shed bit light on what is oVirt saying exactly and why it's not happy that way? many thanks, L.

Future of oVirt as RHV is converging with OpenShift
by andrew.prowse＠gmail.com 06 Feb '21

06 Feb '21

What is the future of oVirt with RHV 4.4 being the last RHV release? - see https://access.redhat.com/support/policy/updates/rhev With the release of RHV 4.4 Red Hat continues to invest in and support customers with a production-ready virtualization portfolio. The latest addition to this portfolio is OpenShift with OpenShift Virtualization, which provides continuity and roadmap delivery for the KVM-based virtualization stack currently managed by RHV. Moving forward the RHV management feature set will be converged with OpenShift and OpenShift Virtualization providing customers with requirements for containers and VMs a migration path and a common platform for deploying and managing both.

[ANN] oVirt 4.4.5 Fourth Release Candidate is now available for testing
by Lev Veyde 05 Feb '21

05 Feb '21

oVirt 4.4.5 Fourth Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.5 Fourth Release Candidate for testing, as of February 4th, 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.

Upgrade from 4.4.3 to 4.4.4 (oVirt Node) - vdsmd.service/start failed with result 'dependency'
by Marco Fais 04 Feb '21

04 Feb '21

Hi all, I have just upgraded one of my oVirt nodes from 4.4.3 to 4.4.4. After the reboot, the 4.4.4 image is correctly loaded but vdsmd is not starting due to this error: vdsmd.service: Job vdsmd.service/start failed with result 'dependency'. Looks like it has a dependency on mom-vdsm, and this as well has a dependency issue: mom-vdsm.service: Job mom-vdsm.service/start failed with result 'dependency'. After some investigation looks like mom-vdsm has a dependency on ovsdb-server, and this is the unit creating the problem: ovs-delete-transient-ports.service: Starting requested but asserts failed. Assertion failed for Open vSwitch Delete Transient Ports Failed to start Open vSwitch Database Unit. Details below: -- Unit ovsdb-server.service has begun starting up.

ovirt AD issue
by Jason Keltz 04 Feb '21

04 Feb '21

A while back, I had reconfigured my oVirt engine to auth based on my Samba AD server, and everything was working perfectly fine. oVirt version 4.3.10.4-1. Today, I tried to login with my account into engine and I see: server_error: The connection reader was unable to successfully complete TLS negotiation: SSLHandshakeException(sun.security.validator.ValidatorException: No trusted certificate found), ldapSDKVersion=4.0.7, revision=b28fb50058dfe2864171df2448ad2ad2b4c2ad58 I recently added a secondary domain controller with Samba, and I realize now that there is an error. Since I didn't pre-initialize samba with a TLS certificate, it generated a new CA, and certificate and key for the second server. Since I'm not using the same CA as the first server, ovirt engine (which only has the CA of the first server) won't be able to talk to the second server... no problem.... I will fix that eventually. However, when I re-ran "ovirt-engine-extension-aaa-ldap-setup", and followed the exact steps I did before, ovirt is connecting to the first server, failing with the above error, then connecting to the second server, and the same error. The CA hasn't changed for the first server, nor has the certificate/key. I verified that the CA certificate that I am giving ovirt is matching with the exact CA certificate of the first server. How can I debug further? Jason.

Recovery from power outage
by Roderick Mooi 04 Feb '21

04 Feb '21

Hi! We had a power outage and all our servers (oVirt hosts) went down. When they started up neither the hosted-engine nor VMs were started. hosted-engine --vm-status says: You must run deploy first I tried running deploy with various options but ultimately get stuck at: The Host ID is already known. Is this a re-deployment on an additional host that was previously set up (Yes, No)[Yes]? ... [ ERROR ] Failed to execute stage 'Closing up': <urlopen error [Errno 113] No route to host> OR The specified storage location already contains a data domain. Is this an additional host setup (Yes, No)[Yes]? No [ ERROR ] Re-deploying the engine VM over a previously (partially) deployed system is not supported. Please clean up the storage device or select a different one and retry. NOTES: 1. This is oVirt v3.6 (legacy install, I know...) 2. We do have daily engine backups (.bak files) [till the day the power failed] Any advice/assistance appreciated. Thanks! Roderick

Changes between Node NG 4.4.3 and 4.4.4
by Shantur Rathore 03 Feb '21

03 Feb '21

Hi, I have a node 4.4.3 install and it works perfectly for PCI passthrough. After I upgraded to Node NG 4.4.4 the PCI passthrough leads to server resets. There are no logs in the kernel messages just before reset apart from vfio-pci enabling the device. So, I assume there is some change related to the kernel or vfio-pci driver in the newer 4.4.4 version. How / Where can I see the differences between Node NG releases? Thanks, Shantur

Single Node 4.3 to 4.4 help
by Wesley Stewart 03 Feb '21

03 Feb '21

I have read through many posts and I think this process seems fairly simple. https://www.ovirt.org/documentation/upgrade_guide/#SHE_Upgrading_from_4-3 But I just wanted to see if anyone had any gotchas. I am thinking of either using - RHEL8 (Using developer program, probably best best atm) - Ovirt Node (Is ovirt node being deprecated since it is based on centos?) - Rocky Linux/AlmaLinux/Clear Linux From my understanding I should: - Enter global maintenance - Make a full engine backup - Reinstall to a supported OS - Deploy ovirt engine using backup. Looking forward to trying out Ovirt 4.4!

Good morning all, On my ovirt 4.4.4 cluster, I am trying to use VLan's to separate VM's for security purposes. Is there a usable how-to document that describes how to configure the vlan's so they actually function without taking the host into non-operational mode? Thank you in advance. Regards, David Johnson

Hi, all. I deployed a new oVirt 4.4.4 installation and imported FC storage domains. However, two storage domains turned out to be empty - they did not have virtual machines in the "VM import" tab, the virtual disks appeared in the "disk import" tab with empty aliases. I downloaded and viewed the OVF_STORE - the old information was partially overwritten by the new one with an empty number of VMs. Trying to restore the VM configuration information, I deployed a backup of the old hosted engine. Version is also 4.4.4. Thus, it was possible to restore OVF_STORE of the first problematic disk domain. But the second storage domain gave an error when updating OVF_STORE. The same error occurs when trying to export a VM or copy a virtual disk to another known good storage domain. At the same time, I successfully download disks from the second storage domain to my PC by clicking the Download button and saving *.raw. But snapshots cannot be saved like this. 1. How can I overwrite OVF_STORE on the second storage domain? If for this I need to restore the oVirt metadata on the storage domain, how can I do it correctly? 2. How can I download VM configuration that has been saved in the hosted engine? Thanks in advance for your help. WBR, Yury Valitsky

ovirt 4.4 and CentOS 8 and multipath with Equallogic

Hello, I'm upgrading some environments from 4.3 to 4.4.

Mellanox SR-IOV
by Jorge Visentini 02 Feb '21

02 Feb '21

Hi. I have a Mellanox card with two ports and I enabled SR-IOV, however in Engine it shows only 1 of the ports with SR-IOV enabled. I shared it on the host through the CLI and shared it right but the VMs do not travel and the Engine shows that only one of the ports is divided. When I try to divide by the Engine, it shows the error of the attached print. Is this information correct or am I doing something wrong?

Users cannot create disks in portal
by jwmccullen＠pima.edu 02 Feb '21

02 Feb '21

Help, banging my head against a wall. Ovirt Engine Software Version:4.4.4.7-1.el8 RHEL 8.3 I have set up my cluster going to a TrueNAS storage. Everything is going great and works well from Admin or any user with SuperUser. I would like to set it up so that students can create their own machines. Great, plowing through the documentation it looks like after creating a user, it works well by giving them at the Data Center object the user roles of: PowerUserRole VmCreator At that level, according to my reading of the documentation, it is also supposed to grant DiskCreator automatically. Well, when I do that it creates the VM but the creation of the disk does not work. Looking in the log I find: Validation of action 'AddImageFromScratch' failed for user will@internal-authz. Reasons: VAR__TYPE__STORAGE__DOMAIN,NON_ADMIN_USER_NOT_AUTHORIZED_TO_PERFORM_ACTION_ON_HE Could anyone please let me know what this is referring to? I have tried many roll combinations, and have even made my own user roll with full privileges to no avail. I looked for issues and the closest I could find is: Bug 1511697 - [RFE] Unable to set permission on all but Hosted-Engine VM and Storage Domain Which showed as resolved in 4.3 Could someone be kind enough to maybe tell me where I am missing it? I'll be the first to admit I can be a little slow at times. Thanks.

Achieving high availability
by Andrea Chierici 02 Feb '21

02 Feb '21

Hi, I am trying to configure high availability on a critical VM. My ovirt version is 4.3.10.4-1.el7. My question is about the best settings to specify, since it's not completely clear to me how they influence the availability. What I want is simply to have a specific machine ALWAYS running, or at least, to be available as much as possible. I have no special requirements on the VM, if it goes down, simply restarting it is fine. Here is my current setting. Is it good or I'd better chage anything? Thanks, Andrea -- Andrea Chierici - INFN-CNAF Viale Berti Pichat 6/2, 40127 BOLOGNA Office Tel: +39 051 2095463 SkypeID ataruz --

oVirt Storage DRS feature
by divan＠santanas.co.za 02 Feb '21

02 Feb '21

Greetings all :) I'm wondering if oVirt supports the feature that VMware does, which is in VMware land is called SDRS [1]. The idea is simple and I'm sure you all aware of it. You have a "cluster" of storage domains, the engine monitors the backend storage domains and auto balances the VMs across the storage domains based on IO latency and disk usage. If not, how are others out there managing this? One could manually balance, but that's clearly not ideal. [1]: https://www.youtube.com/watch?v=z77xmaxoNec -- Divan Santana https://divansantana.com
