hi! i finally found out that it was all just a configuration problem inside my guest :-) for anyone having the same problem: qemu myimage -serial stdio -nographic is totally sufficient as long as you tell linux to start getty listening on a serial console (make sure that GRUB tells your kernel to include "console=/dev/ttyS0"). in my case (a newer debian system) this was adding a file to /etc/event.d/ called "ttyS0" containing the line /sbin/getty -L /dev/ttyS0 38400 vt100 maybe it helps someone :-)
