[Users] oVirt Node - HP ProLiant Installation Failing

Heya, I have a HP ProLiant DL380 G5. I have tried about all available Node ISO's but each fails during the partitioning. Error refers to the file : "install.py" .. with error : global name 'disk' is not defined I have an evaluation version of the lates RHEV Hypervisor and that does install fine. Any pointers or ideas ? Regards
