Cannot sync networks
by Roderick Mooi 25 May '16

25 May '16

Good day On oVirt 3.6.4 HE. I manually reconfigured host networks by doing the following: 1. Changed to global maintenance mode 2. Shutdown the hosted engine 3. on each host: a. systemctl stop ovirt-ha-agent && systemctl stop ovirt-ha-broker && systemctl stop vdsmd b. updated /var/lib/vdsm/persistence/netconf/nets to match the required config c. updated ifcfg files to match d. rebooted each host 4. When all is up and running again, verified network connectivity and settings on each host - ok. 5. Logged into engine web UI - all hosts detected but show network out-of-sync (see attached example). 6. Individual sync / sync all networks runs for a while till login time out. Log back in and go to host - still shows out-of-sync (even next day or after rebooting again). 7. Eventually got one host to sync (not hosting any VMs and rebooted). 8. Whatever I try cannot get the other hosts to sync (even when moving all VMs off and rebooting). Any ideas? Do I have to manually edit the database and change the network settings for the DC - if so, how do I do this? (the host config is what I want - DC is old config.) Alternatively, if I have to start all over again, what is the correct way for changing networks post HE install (I need this as the network for installation and testing looks different to the final production network)? Thanks very much, Roderick

How to change host networks?
by Roderick Mooi 25 May '16

25 May '16

Good day I would like to change the IP addresses of the host networks used by Ovirt including the ovirtmgmt bridge. I need to move them to a different subnet post installation. What is the best/safest way to do this? Thanks, Roderick Mooi Senior Engineer: South African National Research Network (SANReN) Meraka Institute, CSIR roderick(a)sanren.ac.za | +27 12 841 4111 | www.sanren.ac.za

How to setup host network to link ovirtmgmt with eth0 automatically?

Hi, When I install a host, it fails with: 2016-05-24 07:00:01,749 ERROR [org.ovirt.engine.core.bll.SetNonOperationalVdsCommand] (DefaultQuartzScheduler_Worker-4) [1bf36cd4] Host 'node3' is set to Non-Operational, it is missing the following networks: 'ovirtmgmt' 2016-05-24 07:00:01,781 WARN [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (DefaultQuartzScheduler_Worker-4) [1bf36cd4] Correlation ID: 1bf36cd4, Job ID: db281e8f-67cc-441a-b44c-90b135e509bd, Call Stack: null, Custom Event ID: -1, Message: Host node3 does not comply with the cluster Default networks, the following networks are missing on host: 'ovirtmgmt' After I click the "Hosts" -> subtab "Network Interfaces" -> "Setup Host Networks" on the web ui and drag ovirtmgmt to "Assigned Logical" to link with eth0, then activate host "node3" successfully. My question is how to make such manual operation automatically? Then I can run some automatic tests. Thanks a lot. --Kai

Downgrade ovirt-engine 3.6 to 3.5
by Sandvik Agustin 24 May '16

24 May '16

Hi users, Is it possible to downgrade ovirt-engine 3.6 to 3.5 if I remove this http://resources.ovirt.org/pub/yum-repo/ovirt-release36.rpm <http://resources.ovirt.org/pub/yum-repo/ovirt-release35.rpm> then install this http://resources.ovirt.org/pub/yum-repo/ovirt-release35.rpm and run this command? # yum update "ovirt-engine-setup*"? TIA Sandvik

Ovirt + OpenVSwitch
by Sverker Abrahamsson 24 May '16

24 May '16

Has anybody succeeded in installing Ovirt 3.6 with hosted engine on a server which uses OpenVSwitch for the network config? I believe my issue is that Ovirt wants to control the network to create a bridge for its management and I wants it to just use whatever network is available on the host without trying to be clever about it. I was able to tweak it to get to the final stage where it fails on waiting for the engine to start. Best regards Sverker

[ANN] oVirt 3.6.6 Final Release is now available
by Sandro Bonazzola 23 May '16

23 May '16

The oVirt Project is pleased to announce today the general availability of oVirt 3.6.6. This latest community release includes new features and bug fixes for - oVirt Engine - oVirt Engine Appliance - oVirt Engine DWH - oVirt Engine Extension AAA JDBC - oVirt Engine Extension AAA LDAP - oVirt Hosted Enging HA - oVirt Hosted Engine Setup - oVirt VMConsole - VDSM - VDSM JsonRPC Java oVirt is an open-source, openly-governed enterprise virtualization management application, developed by a global community. You can use the oVirt management interface (oVirt Engine) to manage hardware nodes, storage and network resources, and to deploy and monitor virtual machines running in your data center. If you are familiar with VMware products, oVirt is conceptually similar to vSphere. oVirt serves as the bedrock for Red Hat's Enterprise Virtualization product, and it is the "upstream" project where new features are developed prior to their inclusion in Red Hat's supported product offering. Notes: * A new oVirt Live ISO, oVirt Engine Appliance and oVirt Node Next Install ISO will be available soon * Mirrors might need up to one day to synchronize. Additional Resources: * Read more about the oVirt 3.6.6 release highlights: http://www.ovirt.org/release/3.6.6/ * 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/ -- Sandro Bonazzola Better technology. Faster innovation. Powered by community collaboration. See how it works at redhat.com
