From: "Eli Mesika" <emesika(a)redhat.com&gt; To: "devel" <devel(a)ovirt.org&gt; Sent: Wednesday, July 8, 2015 3:22:23 PM Subject: Reaming VdcFault to EngineFault You may get the following error after rebase with master : http://pastebin.test.redhat.com/295552

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. Thanks Eli Mesika

Didi, just to be on the safe side, please approve that command_entities table content is deleted upon upgrade. If not, I will issue also an upgrade script that will fix this issue
