I've been trying out qemu to play around with some VMs. It's working well but I keep wanting to be able to view the text (linux boot process) that quickly scrolls by in the qemu window on startup of my linux virtual machine. Is there any way to retrieve this via qemu?

assuming that gets sent to a virtual serial port - this may need some setup on the guest OS end -try appending '-serial file:FILENAME' to the command you use to start qemu

Fantastic. Thank you. I ended up appending the following: -append console=ttyS0,38400 -serial file:serial.out –  Brad Apr 11 '11 at 19:07
