[Users] oVirt 3.1 - engine configuration problem

Hi, I'm building oVirt engine 3.1 from source on Scientific Linux 6.3. I'm working on branch origin/engine_3.1. During startup the application throws following error: 2013-02-21 11:53:33,768 WARN [org.ovirt.engine.core.utils.ConfigUtilsBase] (MSC service thread 1-22) Could not find enum value for option: CbcCheckOnVdsChange 2013-02-21 11:53:33,995 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (MSC service thread 1-22) Failed to decryptData must start with zero 2013-02-21 11:53:33,996 ERROR [org.ovirt.engine.core.dal.dbbroker.generic.DBConfigUtils] (MSC service thread 1-22) Failed to decrypt value for property CertificatePassword will be used encrypted value 2013-02-21 11:53:34,000 WARN [org.ovirt.engine.core.utils.ConfigUtilsBase] (MSC service thread 1-22) Could not find enum value for option: ENGINEEARLib 2013-02-21 11:53:34,001 WARN [org.ovirt.engine.core.utils.ConfigUtilsBase] (MSC service thread 1-22) Could not find enum value for option: CAEngineKey 2013-02-21 11:53:34,008 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (MSC service thread 1-22) Failed to decryptData must start with zero 2013-02-21 11:53:34,009 ERROR [org.ovirt.engine.core.dal.dbbroker.generic.DBConfigUtils] (MSC service thread 1-22) Failed to decrypt value for property AdminPassword will be used encrypted value 2013-02-21 11:53:34,015 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (MSC service thread 1-22) Failed to decryptData must start with zero 2013-02-21 11:53:34,015 ERROR [org.ovirt.engine.core.dal.dbbroker.generic.DBConfigUtils] (MSC service thread 1-22) Failed to decrypt value for property LocalAdminPassword will be used encrypted value 2013-02-21 11:53:34,020 WARN [org.ovirt.engine.core.utils.ConfigUtilsBase] (MSC service thread 1-22) Could not find enum value for option: MinimalETLVersion 2013-02-21 11:53:34,024 WARN [org.ovirt.engine.core.utils.ConfigUtilsBase] (MSC service thread 1-22) Could not find enum value for option: ScriptsPath 2013-02-21 11:53:34,025 WARN [org.ovirt.engine.core.utils.ConfigUtilsBase] (MSC service thread 1-22) Could not find enum value for option: SQLServerI18NPrefix 2013-02-21 11:53:34,071 ERROR [org.ovirt.engine.core.engineencryptutils.EncryptionUtils] (MSC service thread 1-22) Failed to decryptData must start with zero 2013-02-21 11:53:34,072 ERROR [org.ovirt.engine.core.dal.dbbroker.generic.DBConfigUtils] (MSC service thread 1-22) Failed to decrypt value for property TruststorePass will be used encrypted value It seams to be a configuration problem. I followed this manual http://www.ovirt.org/Engine_Node_Integration (section Engine core machine). Is this manual up to date? Best regarts, Piotr
