A 'channel':
- is a low-bandwidth private communication channel that resembles
a physical serial port.
- is implemented as a PV console with a well-known string name
which is used to hook the channel to the appropriate software
in the guest (i.e. some kind of guest agent).
- has a backend 'connection' which describes what should happen
to the data.
The following 'connection' types are defined:
* PTY: the I/O surfaces as a pty in the backend domain
* SOCKET: a listening Unix domain socket accepts a connection in
the backend domain and proxies
Channels may be listed but don't currently support hotplug/unplug.
