I have recently setup a ovirt hosted engine on iscsi storage and after a reboot of the system I am unable to start the hosted engine.  The agent.log gives errors indicating there is a missing value in the vm.conf file, but the vm.conf file does not appear in the location indicated.  There is no error indicated when the agent attempts to reload the vm.conf.  Any ideas on how to get the hosted engine up and running?
