Hi,
A bit more on this - as I have been trying to get it working ... :-).
The command you provided did work if I use /dev/tty in place of stdio (i.e. -serial /dev/tty) ... except that it only "starts" to work once I have a login prompt in QEMU (and then also in my command window). I'm trying to capture all the Linux boot info / messages prior to that. Any idea how to get this info to show up in my console window (where I'm executing qemu from)?
Thanks!

Hi,
I assume that you tried this (as it was suggested by an earlier mail):
qemu -serial stdio -nographic ...
This results in an error message for me, too:
chardev: opening backend "stdio" failed
qemu: could not open serial device 'stdio': No such file or directory
Try this variant (which works for me):
qemu -nographic ...
It will redirect the serial output (first serial port) of your guest os to
standard output, so you can write it to a file with the usual methods,
for example this one:
qemu -nographic ... | tee log.txt
