[ovirt-users] Problem deploying ovirt-hosted-engine to iSCSI

Hi, I'm back to testing oVirt again but have come across a problem when trying to deploy the ovirt hosted engine with iSCSI. The deploy asks questions about iSCSI, finds the iSCSI target, asks for the iqn, then goes to start the storage server but stops there, hanging forever. In this state I can see that the iSCSI session has logged in and the drive appears in the system (as sdb) but that's it. It appears as though it's getting stuck when it tries to get the list of luns. Has anyone else come across this issue? Any ideas where I can start with troubleshooting? Cheers, Justin.
