Hmm… it seems what I *really* forgot to do was remove that entire section and 
point to the feature doc instead.  It’s quite out of date now (e.g., cdrom 
insert should work I think, qemu is chrooted so can’t read world-readable 
files, &c).  With your permission I’ll put fixing that up properly on a to-do 
list (to be done before 4.12 release at a minimum).
