how does host's status changes ? Especially Unassigned or NonOperational or NonResponsible
by lifuqiong＠sunyainfo.com 15 Jan '21

Hi all, I'm confusing in Host's status in Ovirt Eninge. When will the host's status become Unassigned or NonOperational or NonResponsible? and If the host's status change to these statuses, What will ovirt response to it? After reading Ovirt Engine's source code, I find Only HostMonitoring.java and AutoRecoveryManager.java will change the status of Host. for example, If the host's status is changed to NonOperational, The AutoRecoveryManager will traverse the NonOperational hosts and calling ActivateVdsCommand.java, which will only set the Host's status to Unassigned ? But I don't know What's the next step? So where I can find the article or manual or other helpful information about this question? Thank you . Your sincerely Mark

Using Ansible ovirt_vm
by Matthew.Stier＠fujitsu.com 15 Jan '21

15 Jan '21

Over this weekend, I need to shutdown and restart 1500 VMs while I do work. Modifying an Ansible playbook I have, to accomplish that, seems easy enough. Last weekend I used the web gui and edited each Virtual Machine and changed the 'cluster' to the one I wanted to assign it too. Now I would like to automate this with Ansible. In between shutting them down and starting them up, I need to change the cluster registration of quite a few of the hosts, and I have concerns on how to do that. The Ansible ovirt_vm documentation on this is a bit fuzzy. I'm assuming it for assigning the cluster, but in some examples it appears to be used as a filter. Which changes the meaning. Is it "start the VM in this cluster" or "start this VM if it is in this cluster". The playbook I'm working from is straight forward and has three tasks. First, an ovirt_auth task to log into the SHE. Second, an ovirt_vm task which loops though the group of virtualmachines, defined in an 'ini' file. Third, an ovirt_auth task to logout from the SHE. For stopping, I assume I specify a name, and state to 'stopped' and that should initiate the shutdown. For starting, I assume I should set the state to 'running'. For changing the cluster a vm is assigned to, do I simply need to use the 'cluster' parameter with a value of new cluster? Are there other actions that need to be taken? The VM need to be un and re-registered for the change to take effect? I'd like to make the cluster change individual playbook, but could it be added to the start or stop playbook. (ie: stop and change cluster, start on new cluster) Waiting for the wisdom of the community.

Networking question on setting up self-hosting engine

[ANN] oVirt 4.4.5 First Release Candidate is now available for testing
by Lev Veyde 14 Jan '21

14 Jan '21

oVirt 4.4.5 First Release Candidate is now available for testing The oVirt Project is pleased to announce the availability of oVirt 4.4.5 First Release Candidate for testing, as of January 14th, 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.

Q: oVirt 4.4.4.7 Node settings on CentOS Stream
by Andrei Verovski 14 Jan '21

14 Jan '21

Hi ! I’m installing new oVirt 4.4.4 node on CentOS Stream and its seems there are some changes since older node on CentOS 7.x. 1) NFS shares for storage domain. In 7.x I used chown -Rv nfsnobody:nfsnobody /vmraid/nfs; chmod -Rv 755 /vmraid/nfs In Stream nfsnobody don’t exists, should I use: chown -Rv nobody:nobody /vmraid/nfs; chmod -Rv 777 /vmraid/nfs Is that correct settings? 2) SELinux seems to be more permissive now, looks like I don’t have to tweak it to have my custom cron and SNMP scripts running. Yes, SELinux is running, getenforce -> yields “Enforcing”. Will oVirt sw node installation change this behaviour? Thanks in advance Andrei

Networking question on setting up self-hosting engine
by netgoogling＠gmail.com 14 Jan '21

14 Jan '21

Dear list, I have tried setting up self-hosting engine on a host with ONE Nic (Ovirt 4.4 CentOS 8 Stream). I followed the Quick Start Guide, and tried the command line self-host setup, but ended up with the following error: {u'msg': u'There was a failure deploying the engine on the local engine VM. The system may not be provisioned according to the playbook results.... I tried on another host with TWO NICs (Ovirt 4.3 Oracle Linux 7 Update 9). This time I setup a bridge BR0 and disable EM1 (the first Ethernet interface on the host), and then created Bond0 on-top of BR0. Both Bond0 and EM2 (the second Ethernet interface on the host) were up. And then I tried again using Ovirt-Cockpit wizard, with the Engine VM set on BR0, and the deployment of Engine VM simply failed. The Engine and Host are using the same network numbers (192.168.2.0/24) and they resolved correctly. I read the logs in var/log/ovirt-engine/engine.log but there wasn't any error reported. I have already tried many times for the past few days and I'm at my wits-end. May I know: 1) Is it possible to install Self-hosted engine with just ONE NIC? 2) Any suggestion how to troubleshoot these problems? And tested network configurations? Hope to hear from you. Thanks.
