The scsi hdd controller is a BusLogic Parallel, set from wmvare converter by default. I don't know if it's good for GOS.
Check that on the source machine. If it's good, lsmod should list something with 'buslogic'. I would rather expect 'mptbase' / 'mptscsih' which means LSI Logic
In order to check if the virtual disk is good, can i mount it with the vsphere console ?
I don't understand what you mean
