AFAIK kubevirt removed support for virtIO for CD-ROMS, another PR removed the virtio option for cdroms so you won't see it in the list now. Is this sufficient Ruth?
Note: https://bugzilla.redhat.com/show_bug.cgi?id=1838397 - removed ivrtio as option for cd-roms
Gilad - the probelm here i sthat virtio is not availabe when choosing cd-rom (and saving) and then changing to disk (which should have virtio option).
