[Engine-devel] Error on starting webadmin

[Vojtech Szocs]

Hi,

I've updated http://www.ovirt.org/Building_Engine_Draft - added section "Engine local configuration" (feel free to edit or modify as necessary)

Hi guys,

as Moti mentioned, this issue is related to UI plugins patches that have been merged recently.

However, the root cause of this issue is LocalConfig class (machine-specific Engine configuration) throwing exception in following cases:
- cannot load default properties (ENGINE_DEFAULTS property if defined, otherwise /usr/share/ovirt-engine/conf/engine.conf.defaults)
- cannot load custom properties (ENGINE_VARS property if defined, otherwise /etc/sysconfig/ovirt-engine)
- requesting missing property value (LocalConfig.getProperty method)

(Note that UI plugins use two Engine properties: ENGINE_USR and ENGINE_ETC.)

As Juan suggests in his comment in http://gerrit.ovirt.org/#/c/10026/, we could include this in "building Engine" wiki. For example:
- have ENGINE_DEFAULTS property point to OVIRT_HOME/backend/manager/conf/engine.conf.defaults (alternatively, users can copy this file to /usr/share/ovirt-engine/conf)
- create custom Engine config file, e.g. ~/myengine.conf, and have ENGINE_VARS property point to this file

You can use the 'engine.conf.defaults' that resides at 'backend/manager/conf'.
