# Answering the use-case question OK that feels like being stuck because: - the bug report sounds reasonable - just as the upstream reason to disable it is.
*sigh* To unblock this I've had some discussions/communications and want to thank Andrey for facilitating these. The question that was left open for me and many others was "what exactly are the use cases here that we would break or continue to support". We had many words and quotes on why it should not be enabled, but no deeper reason yet why to keep it for to outweigh this. That is an indirect answer to Lukas who asked in comment 4 > Would you mind elaborating a bit more on your usecase and why you'd want to build upon such supposedly "obsolete equipment"? I found that this isn't used for anything recent, modern or new - which is a relief. The use case seems to be mostly about keeping old VMs created in other environments alive. Think VMware created paravirt SCSI setups that you can't yet renew for real. In the related Debian discussion [1] the same was mentioned: "Most common use case is probably bootimg images created on other hypervisors on qemu. Otherwise there is little reason to use something which is not virtio-scsi." Others [2] re-added PVSCSI (but not MPT btw) and it is still there - they were not keen on reasons in that commit but it is quite likely the same use case of allowing to run guests created elsewhere as it isn't how they set up new guests either. I think with that - keeping old paths alive, but not using it for something new - I feel much better. OK, so we have a motivation to enable this again and are looking for version 2 of "c) compromises ..."
