I was referring to the domain's console rather than the serial

In the unstable tree, if you're running a 'getty' on the domain's
tty0 you should be able to log in and poke around even if
the domain's networking or sshd is screwed. The domain's console
will be presented as a TCP socket on domain0 (e.g. 
"xencons localhost 9601" )

For domain0, you should be able to login over the serial line
with a getty on ttyS0.
