Isn't this a vDPA/VFIO problem? There's no requirement
for RAM MemoryRegions to be aligned in any way. Code
that doesn't want to work with small or weirdly aligned
regions should skip them if that's the right behaviour
for that particular code IMHO.
Marc-André proposed to modify vDPA code to skip the region but Michal disagreed:

No one wants the modification, so the problem cannot be fixed.
Thanks,
