You may get the following error after rebase with master :
If you can not see this , the error is : 2015-07-08 12:59:21,322 ERROR [org.ovirt.engine.core.vdsbroker.HostMonitoring] (DefaultQuartzScheduler_Worker-5) [5766d7b4] Exception: javax.ejb.EJBException: org.apache.commons.lang.SerializationException: org.codehaus.jackson.map.JsonMappingException: Invalid type id 'org.ovirt.engine.core.common.errors.VdcFault' (for id type 'Id.class'): no such class found (through reference chain: org.ovirt.engine.core.common.action.VdcReturnValueBase["fault"])
The reason is that the CommandEntity has a memeber of type VdcReturnValueBase which contains the VdcFault. It is serialized by jackson into the db, and when there is an attempt to deserialize it - you got the error.
This can be addressed by a simple update command followed by engine restart:
psql -U <user> -c "update command_entities set return_value = replace(return_value,'VdcFault','EngineFault'), return_value_class = replace(return_value_class,'VdcFault','EngineFault');" <db>
Please let me know if you have any issues.
