oVirt 4.1.1 and ovn problems
by Gianluca Cecchi 25 Apr '17

25 Apr '17

Hello, I installed some months ago a test setup in 4.1.0 with ovn. Now after updating engine and host to 4.1.1 it seems the services are up but it doesn't work. If I run a VM with a network device in OVN external provider, it cant' boot and I get this in engine.log: 2017-04-20 15:17:42,285+02 ERROR [org.ovirt.engine.core.dal.dbbroker.auditloghandling.AuditLogDirector] (org.ovirt.thread.pool-6-thread-11) [e55e0971-f1e5-4fda-8666-3ce23797027f] EVENT_ID: USER_FAILED_RUN_VM(54), Correlation ID: e55e0971-f1e5-4fda-8666-3ce23797027f, Job ID: 067f6e70-9e70-48bc-be44-d5bd1d9485fd, Call Stack: null, Custom Event ID: -1, Message: Failed to run VM c6 (User: admin@internal-authz). 2017-04-20 15:17:42,317+02 INFO [org.ovirt.engine.core.bll.RunVmCommand] (org.ovirt.thread.pool-6-thread-11) [e55e0971-f1e5-4fda-8666-3ce23797027f] Lock freed to object 'EngineLock:{exclusiveLocks='[50194eea-f96d-4ebb-bf64-55cef13f4309=<VM, ACTION_TYPE_FAILED_OBJECT_LOCKED>]', sharedLocks='null'}' 2017-04-20 15:17:42,317+02 ERROR [org.ovirt.engine.core.bll.RunVmCommand] (org.ovirt.thread.pool-6-thread-11) [e55e0971-f1e5-4fda-8666-3ce23797027f] Command 'org.ovirt.engine.core.bll.RunVmCommand' failed: EngineException: (Failed with error PROVIDER_FAILURE and code 5050) Firewall is disabled/stopped at host and engine side (where I installed the central server too) and should not be the problem....

Do I need to run these two commands? Or any other configuration settings? Thanks in advance, Gianluca

After installing self hosted engine/appliance, the host is unable to commun= icate to web resources on em1. Ovirtmgmt is on the bond and has no comms i= ssues. I installed the logical network for the external web side per the online do= cs and attached it to em1. Host system can ping the network gateways on each NIC. When launching firef= ox, system is able to browse to Hosted-engine VM page (admin portal, user p= ortal , etc) but is unable to get to web sites (i.e. google, ovirt.org, etc= .) I read that Ovirt 4.1 was supposed to have fixed the multiple gateway issue= , but am confused as to why I can't get out. Any ideas how I can get the host to browse the web again?

Hyperconverged Setup and Gluster healing

I always try to stay= on the current version and I'm applying updates/upgrade if there are any. = For this I put a host in maintenance and also use the "Stop Gluster Service= " checkbox.

after upgrade from 4.0.4 to 4.1.1, no more gettagsbyparent_id
by Fabrice Bacchella 24 Apr '17

24 Apr '17

I tried to upgrade from 4.0 to 4.1, I ran engine-setup And now ovirt-engine start fails with command like: Caused by: org.springframework.jdbc.BadSqlGrammarException: PreparedStatementCallback; bad SQL grammar [select * from gettagsbyparent_id()]; nested exception is org.postgresql.util.PSQLException: ERROR: function gettagsbyparent_id() does not exist In the setup log I indeed found: drop function if exists public.gettagsbyparent_id(uuid) cascade; But nothing else. This function is not recreated. Any hint about what happened ?

Communicate between the guest vm's hosted on different hosts on different data centres using OVS
by Linov Suresh 24 Apr '17

24 Apr '17

Hello, I have configured OVS network on oVirt 4.1.1, following the document https://www.ovirt.org/blog/2016/11/ovirt-provider-ovn/ I have created OVN Provider, and created new Logical Network for OVS using OVN Provider. I have synced the network also selected OVS when I created the cluster. I have two data centres and each data centre has one host each. Now I have created VM's selecting OVS network (not ovirtmgmt). VM's in the same data centre can talk to each other. How do i make the VM's hosted on different data centre can talk to each other? Appreciate your help in advance, Sincerely, Suresh.
