[adding libvir-list as well]

The only non-cosmetic concern I have about your series is the enum
property so I would strongly suggest splitting it. If you did that
for v19, it will be pretty close to merge ready.
Eric,
How does this affect libvirt? could you assume a default set of backends
if "-device ccid-card-emulated,?" returns "backend=string" instead of
"backend=A/B" ?
Hmm. At the moment, libvirt only looks for "ccid-card-emulated" in the
-device ? list, and hasn't yet tried inspecting -device
ccid-card-emulated,? output. In short, libvirt assumes that the
presence of ccid-card-emulated implies that both modes are available
(libvirt's<smartcard mode='host'/> => backend=nss-emulated;<smartcard
mode='host-certificates' => backend=certificates).
Is it possible for
qemu to have support for one, but not both, of those modes? If that's
the case, then supporting "backend=nss-emulated/certificates" in -device
ccid-card-emulated,? would be handy for libvirt (for example, it would
be just "backend=certificates" if nss-emulated is not available). But
if it's an all-or-none approach (all backends are available if
ccid-card-emulated is present), then libvirt's current code won't be
impacted by changing the string to the simpler "backend=string".
