No, but I'd be interested to hear if you find out. Or if the Xen
project would take it as a feature request.

The other terminal-related one I always wondered about was if it
could be possible to remap "magic sysrq" (ctrl-o on Xen console).

This is all very well in dom0's console, but in guests I have users
that persist in using nano editor where ctrl-o is save file! So they
hit ctrl-o expecting to save the buffer, but seemingly nothing
happens (Xen is waiting for the magic sysrq command), so they try
ctrl-o again which comes across as magic sysrq command 'o' -
immediate power off!

So in guests, if ctrl-o can't be remapped I'd quite like to disable
it I think.

Other interesting console-related things that I think are already
possible but I lack knowledge in how to do it and would appreciate
some tips from anyone who does:

- Is it possible to log all console content for a guest without
  interfering with the ability to start / use "xl console"?

- Has anyone ever plumbed a guest's console through to a web
  terminal setup like xterm.js?

Cheers,
