Hello RE: oVirt 4.3 - Fibre Channel Data Domain as ISO dump. Thanks for letting me join the list. I added a fibre channel Data domain with a view to using it as an ISO dump however I cannot mount CDs to VMs with this error: "Error while executing action Change CD: Drive image file could not be found" A bit of reading suggests there is no way around this when using fibre channel data domains - is this the case? I guess I could present the LUN to a VM and run NFS from there as an alternative option. Thanks a lot Angus
