Well, it's a bit horrible, but as long as you don't need to type the kernel command line by hand it's OK. The code that does the trick is here: https://anonscm.debian.org/cgit/qa/jenkins.debian.net.git/tree/cucumber/features/step_definitions/common_steps.rb#n217 which you can see the result of at about 27 seconds into this: https://jenkins.debian.net/view/lvc/job/lvc_debian-testing-daily/1341/artifact/results/00%3A01%3A57_Install_Debian,_and_boot_to_a_login_prompt,_Examples___1_.mpg What that does is start a while loop that reads from /dev/ttyS0, and runs the commands that you type, returning the STDOUT, STDERR, and result code, separated by various control characters which you probably don't care about. If you do that, then you can use nc (or whatever) to connect to the TCP port which is defined for the KVM's ttyS0, and type commands, and get their output, followed by a result code. It's almost like having a shell prompt, other than the slightly odd ordering of STDERR and the result. It would probably be better to have a udeb that contains a thing for running the listener, like the debugging thing that is available in tails -- theirs returns results in json, and lets one run as users other than root, and can drop thing into the background, but we don't really need all that in d-i.
