[Users] oVirt engine migration howto and some doubts

[Adrian Gibanel]

A happy update on my ovirt-engine migration quest. 

I've finally convinced myself that I had to change oVirt-engine hostname with all these certificate instructions that jhernand mentioned. 

My doubts are about the passwords mentioned in: 
http://wiki.ovirt.org/How_to_change_engine_host_name 
Are you supposed to change them? Or some of them are somehow default oVirt passwords? 

So I've finally do it. oVirt-engine seems to find again all its hosts. I haven't tried to interact with virtual machines (too late right now here) but everything seems ok. 

The oVirt engine migration howto is found here: 

http://www.ovirt.org/User:Adrian15/oVirt_engine_migration 

The only thing that bothers me is finding: 

WARN [org.ovirt.engine.core.bll.GetConfigurationValueQuery] (ajp--0.0.0.0-8009-6) calling GetConfigurationValueQuery (SearchResultsLimit) with null version, using default general for version 

at engine.log. It might have been always there in the OldAIO but just noticed right now? Should I bother? 

Some thoughts: 

* An extra step that nobody predicted was opening ports so that vdsm, libvirt tls, guest consoles, migration and snmp were available. It would seem AIO firewall setup doesn't open them by default and I understand it why... because it's locally, although not opening migration ports makes me think if we cannot achieve migration on default AIO installation. Maybe it's a bug on the all-in-one script that prepares the engine-setup execution? 

* As I've commented I'm glad that oVirt 3.2 database dump script let's you select a file and doesn't save a fixed filename one.

Feedback is welcome so that the wiki page can be improved. Maybe someone can rewrite it to adapt it to official oVirt language and official oVirt wiki style.
