AIUI Clemens wants to redirect the VGA console output, not QEmu monitor. One idea is to dig out my ncurses interface patch (I believe debian has a version that applies to post-9.0 qemu, and if you're on debian just use the "-curses" switch), then GNU screen would let you log all VGA console output to a file. Another idea is to set a breakpoint at the guest printk() address. Regards
