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 23 May '16

23 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

Recommended bonding modes?
by Alan Murrell 23 May '16

23 May '16

Hello, I am wondering what the recommended bonding modes are for the different types of networks: - Management/Display - Guest VM Traffic - Storage (NFS) For the purposes pf this post, assume mode 4 is not available. For Management/Display, I am thinking mode 1 (active-backup) is adequate since there generally isn't a lot of traffic being pushed through. Storage, I like mode 0 (round robin) due to some performance results I have seen, though I understand this has to be setup in "custom bonding". Mode 6 seems like it would do well here as well. Guest VM traffic is the one I am not sure about. There could be a lot of traffic going back and forth, so I would want all the interfaces in the bond active to balance the load. Of the supported bonding modes, either 2 or 5 would seem to be the options. I am just wondering what others' thoughts and experiences are. Thanks! :-) Regards, Alan

Errors while trying to join an external LDPA provider
by Alexis HAUSER 23 May '16

23 May '16

Hi, I'm using 3.6.3.4-1.el7.centos and I'm having troubles joining an LDAP provider. When I try to login into the new profile, I get a "general command validation failure" error. This is what I can get from ovirt-engine/engine.log : tail -n 400 /var/log/ovirt-engine/engine.log | grep -i error 2016-04-28 09:27:08,355 WARN [org.ovirt.engineextensions.aaa.ldap.AuthnExtension] (default task-56) [] [ovirt-engine-extension-aaa-ldap.authn::public-authn] Cannot initialize LDAP framework, deferring initialization.
