Hi, I followed the upgrade to wildfly steps here [1]. And everything worked as expected. I was able to compile/run/update database without issues. However now when I start the engine, everything appears to work but I am getting the following stack trace over and over and over again in my engine log. 2015-06-29 11:47:44,240 WARN [org.ovirt.engine.core.vdsbroker.VdsManager] (DefaultQuartzScheduler_Worker-39) [] Failed to refresh VDS , vds = 'host1' : '932f05b4-e3b0-4e9a-ab99-77ff749138b3', error = 'No enum constant org.ovirt.engine.core.common.businessentities.network.NetworkBootProtocol.1', continuing. 2015-06-29 11:47:44,241 ERROR [org.ovirt.engine.core.vdsbroker.VdsManager] (DefaultQuartzScheduler_Worker-39) [] Exception: java.lang.IllegalArgumentException: No enum constant org.ovirt.engine.core.common.businessentities.network.NetworkBootProtocol.1 at java.lang.Enum.valueOf(Enum.java:236) [rt.jar:1.7.0_79] at org.ovirt.engine.core.common.businessentities.network.NetworkBootProtocol.valueOf(NetworkBootProtocol.java:6) [common.jar:] at org.ovirt.engine.core.dao.network.NetworkAttachmentDaoDbFacadeImpl$NetworkAttachmentRowMapper.mapRow(NetworkAttachmentDaoDbFacadeImpl.java:96) [dal.jar:] at org.ovirt.engine.core.dao.network.NetworkAttachmentDaoDbFacadeImpl$NetworkAttachmentRowMapper.mapRow(NetworkAttachmentDaoDbFacadeImpl.java:79) [dal.jar:] at org.springframework.jdbc.core.RowMapperResultSetExtractor.extractData(RowMapperResultSetExtractor.java:92) [spring-jdbc.jar:3.1.1.RELEASE] at org.springframework.jdbc.core.RowMapperResultSetExtractor.extractData(RowMapperResultSetExtractor.java:1) [spring-jdbc.jar:3.1.1.RELEASE] at org.springframework.jdbc.core.JdbcTemplate$1.doInPreparedStatement(JdbcTemplate.java:649) [spring-jdbc.jar:3.1.1.RELEASE] at org.springframework.jdbc.core.JdbcTemplate.execute(JdbcTemplate.java:587) [spring-jdbc.jar:3.1.1.RELEASE] at org.springframework.jdbc.core.JdbcTemplate.query(JdbcTemplate.java:637) [spring-jdbc.jar:3.1.1.RELEASE] at org.springframework.jdbc.core.JdbcTemplate.query(JdbcTemplate.java:666) [spring-jdbc.jar:3.1.1.RELEASE] at org.springframework.jdbc.core.JdbcTemplate.query(JdbcTemplate.java:706) [spring-jdbc.jar:3.1.1.RELEASE] at org.ovirt.engine.core.dal.dbbroker.PostgresDbEngineDialect$PostgresSimpleJdbcCall.executeCallInternal(PostgresDbEngineDialect.java:154) [dal.jar:] at org.ovirt.engine.core.dal.dbbroker.PostgresDbEngineDialect$PostgresSimpleJdbcCall.doExecute(PostgresDbEngineDialect.java:120) [dal.jar:] at org.springframework.jdbc.core.simple.SimpleJdbcCall.execute(SimpleJdbcCall.java:181) [spring-jdbc.jar:3.1.1.RELEASE] at org.ovirt.engine.core.dal.dbbroker.SimpleJdbcCallsHandler.executeImpl(SimpleJdbcCallsHandler.java:147) [dal.jar:] at org.ovirt.engine.core.dal.dbbroker.SimpleJdbcCallsHandler.executeReadList(SimpleJdbcCallsHandler.java:109) [dal.jar:] at org.ovirt.engine.core.dao.network.NetworkAttachmentDaoDbFacadeImpl.getAllForHost(NetworkAttachmentDaoDbFacadeImpl.java:40) [dal.jar:] at org.ovirt.engine.core.vdsbroker.vdsbroker.HostNetworkAttachmentsPersister.persistNetworkAttachments(HostNetworkAttachmentsPersister.java:69) [vdsbroker.jar:] at org.ovirt.engine.core.vdsbroker.vdsbroker.HostNetworkTopologyPersisterImpl.persistTopology(HostNetworkTopologyPersisterImpl.java:280) [vdsbroker.jar:] at org.ovirt.engine.core.vdsbroker.vdsbroker.HostNetworkTopologyPersisterImpl.persistAndEnforceNetworkCompliance(HostNetworkTopologyPersisterImpl.java:85) [vdsbroker.jar:] at org.ovirt.engine.core.vdsbroker.vdsbroker.HostNetworkTopologyPersisterImpl.persistAndEnforceNetworkCompliance(HostNetworkTopologyPersisterImpl.java:141) [vdsbroker.jar:] at org.ovirt.engine.core.vdsbroker.VdsManager.refreshCapabilities(VdsManager.java:666) [vdsbroker.jar:] at org.ovirt.engine.core.vdsbroker.HostMonitoring.beforeFirstRefreshTreatment(HostMonitoring.java:706) [vdsbroker.jar:] at org.ovirt.engine.core.vdsbroker.HostMonitoring.refreshVdsRunTimeInfo(HostMonitoring.java:128) [vdsbroker.jar:] at org.ovirt.engine.core.vdsbroker.HostMonitoring.refresh(HostMonitoring.java:84) [vdsbroker.jar:] at org.ovirt.engine.core.vdsbroker.VdsManager.onTimer(VdsManager.java:215) [vdsbroker.jar:] at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) [rt.jar:1.7.0_79] at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) [rt.jar:1.7.0_79] at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) [rt.jar:1.7.0_79] at java.lang.reflect.Method.invoke(Method.java:606) [rt.jar:1.7.0_79] at org.ovirt.engine.core.utils.timer.JobWrapper.invokeMethod(JobWrapper.java:81) [scheduler.jar:] at org.ovirt.engine.core.utils.timer.JobWrapper.execute(JobWrapper.java:52) [scheduler.jar:] at org.quartz.core.JobRunShell.run(JobRunShell.java:213) [quartz.jar:] at org.quartz.simpl.SimpleThreadPool$WorkerThread.run(SimpleThreadPool.java:557) [quartz.jar:] After some debugging it appears that the query from the database returns "1" as the value (which is correct as that is the value in the database). But then the NetworkBootProtocol.forValue fails due to the possible values being "NONE", "DHCP", "STATIC". Looking at the stored procedure there doesn't seem to be any translation between 1 and DHCP, so it makes sense for the failure. I compared the stored procedure to a clean new database and they are identical, so I am assuming my database is fine in that regard. If I modify the code to use NetworkBootProtocol.forValue instead of valueOf it works fine, but the valueOf code has been in there for a long time so if that was broken it would have been noticed a long time ago. I am out of thoughts, can anyone help me figure out what is going on? Thanks, Alexander [1] http://lists.ovirt.org/pipermail/devel/2015-June/010832.html
