[Users] VDSM failing to start because iscsid fails to start

I just installed the engine and a few nodes from RPMs all on F16 per the instructions at: http://www.ovirt.org/wiki/Installing_ovirt-engine_from_rpm After installing the engine, I installed a few nodes by installing the minimal F16 package set + wget, configuring the ovirt repo on the nodes and using the 'New' button in the hosts tab of the engine GUI. The installation went fine, but after the nodes rebooted they were listed as non-reponsive. It turned out that VDSM was failing to start because iscsid was failing to start. I turned up the debug level on iscsid but didn't find any culprit. Manually force-starting iscsid and then manually starting the vdsm service caused the nodes to change status to Up. Anybody seen this or have any thoughts about what might be wrong? Dave
