See this commit in the Linux sources:
108fc82596e3b66b819df9d28c1ebbc9ab5de14c
that adds a way to send guest trace data over to the host. I think
that's the most relevant to your use-case. However, you'll have to
add an in-kernel user of virtio-serial (like the virtio-console code
-- the code that deals with tty and hvc currently). There's no other
non-tty user right now, and this is the right kind of use-case to add
one for!
For many other (userspace) use-cases, see the qemu-guest-agent in the
qemu sources.
The API is documented in the wiki:
http://www.linux-kvm.org/page/Virtio-serial_API
and the feature pages have some information that may help as well:
https://fedoraproject.org/wiki/Features/VirtioSerial
There are some links in here too:

Hope this helps.
