Hi Gerd, others,

I am happy to see the work you are doing with modularizing
qemu, but I think there also needs to be corresponding work
with libvirt's ability to properly detect qemu functionality
in light of this modularization.

Right now the QMP interface for probing "spice support" is
quite a big hammer, and doesn't allow for any nuance.

As I've looked into other aspects of how libvirt detects qemu
functionality, it seems there is a lot of room for improvement in how
qemu advertises it's functionality - which goes well beyond the issues
of modularization.

If you have any pointers to and discussion or plans in this regard, I'd
appreciate it. Otherwise I'll look into doing something in this space
myself.

Thanks,

Bruce
