I think it would be a nice option to allow such guest-side "daemon's" to be
executed in the guest context without _any_ guest-side support.
This would be possible by building such minimal daemons that use vmchannel,
and which are built for generic x86 (maybe even built for 32-bit x86 so that
they can run on any x86 distro). They could execute as the init task of any
guest kernel - Qemu could 'blend in / replace' the binary as the init task of
the guest temporarily - and some simple bootstrap code could then start the
daemon and start the real init binary (and turn off the 'blending' of the init
task).
That way any guest could be extended via such Qemu functionality - even
without any kernel changes. Has anyone thought about (or coded) such a
solution perhaps?
