I seem to recall that quite a long time ago--maybe 5 years now--there
was discussion of doing clustering/HA stuff with Linux guests that
used vCTCs as serial devices. Maybe this could do what you want:
Define one octopus guest, the console server, with dozens of CTC
pairs, each coupled to one other guest, and for each connected guest,
have that guest use the CTC serial device as its console.

Now that sounds more like what I'm looking for! Basically virtual
serial cables! Can you suggest where I might find the information to
read up on this? I'll need to figure out all these kinds of details:
*Linux CTC major/minor number info, and commonly used device name.
*Limitations on how many virtual CTC's one Linux host can take (if any).
*Line speed / pseudo baud rate, if applicable?
*Would it use hardware flow control or need software flow control?
If we could get 30-100 or more guests to use these CTC's as their
console devices to one linux appliance, score!
