This is the same limitation as the existing 'virsh console' - John's
merely splitting it into a separate binary, which is what I previously
suggested for making the solaris privilege separation work better in
the context of virsh.

It is also only intended to be used for the text console - we've already
got perfectly good clients for the remote graphical VNC console.
