Sounds almost too good to be true :-)

We are working on setting up a development environment. Once it's up we'll give this patch a spin and report back, probably early next week.

Cheers,

Switching to +devel

Browsing the code a bit, I think a good starting point would be
https://github.com/oVirt/vdsm/blob/500c035903dd35180d71c97791e0ce4356fb77ad/lib/vdsm/storage/managedvolume.py#L110
- if volume_type not in ("rbd", "iscsi"):
+ if volume_type not in ("rbd", "iscsi", "lightos"):

And it's possible that it would be all that's required to make it work
on ovirt >=4.5

The path resolver might warn, but it looks like it would return
/dev/nvme0n so the generated udev rule should come out correct

I'm happy to assist if it turns out to be more challenging (and if not) :)
