Hi all, Now that we've gained some experience with using Redfish virtual media I'd like to reopen the discussion about $subj. For the context, the idrac-redfish-virtual-media boot interface appeared because Dell machines need an additional action [1] to boot from virtual media. The initial position on hardware interfaces was that anything requiring OEM actions must go into a vendor hardware interface. I would like to propose relaxing this (likely unwritten) rule. You see, this distinction causes a lot of confusion. Ironic supports Redfish, ironic supports iDRAC, iDRAC supports Redfish, ironic supports virtual media, Redfish supports virtual media, iDRAC supports virtual media. BUT! You cannot use redfish-virtual-media with iDRAC. Just today I had to explain the cause of it to a few people. It required diving into how exactly Redfish works and how exactly ironic uses it, which is something we want to protect our users from. We already have a precedent [2] of adding vendor-specific handling to a generic driver. I have proposed a patch [3] to block using redfish-virtual-media for Dell hardware, but I grew to dislike this approach. It does not have precedents in the ironic code base and it won't scale well if we have to handle vendor differences for vendors that don't have ironic drivers. Based on all this I suggest relaxing the rule to the following: if a feature supported by a generic hardware interface requires additional actions or has a minor deviation from the standard, allow handling it in the generic hardware interface. Meaning, redfish-virtual-media starts handling the Dell case by checking the System manufacturer (via the recently added detect_vendor call) and loading the OEM code if it matches "Dell". After this idrac-redfish-virtual-media will stay empty (for future enhancements and to make the patch backportable). Thoughts?
