Mice Xia reassigned CLOUDSTACK-1399:
------------------------------------

    Assignee: Kelven Yang

kelven, 
an exceptions is raised when 

s_instance._entityMgr.findById(entity, (Long) field.get(cmd));

UserVmDao is missing in s_daoMaps, a new implementation of UserVmDao, 'RandomlyIncreasingVMInstanceDaoImpl' , was introduced; i have no idea which implementation should be the default one, so i assign this to you.

CLOUDSTACK-1397 is arised by the same root cause.
