Strip back the logic to: * Only try to toggle source_type=memfd and access_mode=shared * Disable the field if guest has any <numa> config * Disable the field if domcaps does not report virtiofs and memfd This is the simplest future proof case, though it will exclude some legit guest configs and some libvirt+qemu back compat. My feeling is the <numa> stuff in particular is pretty advanced, so if users have it configured they can toggle shared memory via the XML without too much trouble.
