* [Qemu-devel] Are there any virtioconsole docs?

I'm trying to replace --nographic sticking the console on the first
serial port with a virtio-based console, and unfortunately the
documentation seems nonexistent.  qemu --help just says "--virtioconsole
c", but that complains about an inability to run an ioctl on something.

The qemu web docs say that --virtioconsole has been replaced by --device
virtconsole but has no other mention of the word "virtconsole" anywhere
else on the page:

  http://qemu.weilnetz.de/qemu-doc.html

And trying it says:

  qemu-system-x86_64: -device virtconsole: No 'virtio-serial-bus' bus
  found for device 'virtconsole'

Google brings up serveral fedora pages involving patches for specifying
devices in some kind of XML:

  http://www.redhat.com/archives/libvir-list/2010-July/msg00589.html

And of course this:

  http://fedoraproject.org/wiki/Features/VirtioSerial

Which seems to document how to connect virtio to a file (pty?  Socket?)
on the host, rather than to the host's stdin/stdout or to the consoles
in the SDL window.

Am I mising something obvious?  Is there a way to do this, or is the
feature either designed for something other than I'm attempting or not
finished yet?
