qemu> help documentation

[Paolo Pedaletti]

Ciao,
I have trouble to get full list of the output of
qemu> help
inside kvm when I switch to second console CTRL-ALT-2

I can't find the full list even inside source code (apt-get source 
qemu-kvm) and neither inside binary file (grep blockarg qemu-*)

Is it possible to redirect the output of "> help" on an external file? 
Or paging it?

This because (the main problem is) I'm trying to get full kernel message 
at boot, but inside KVM window it's not possible to scroll up ( goal: 
http://pedalinux.blogspot.it/2013/02/physical-to-virtual-step-by-step.html 
) or to dump outside terminal output.

I hope to find something useful in qemu help.

Thank you.

Try Ctrl+PageUp.

If that doesn't work you can put the monitor on stdio like this:

  $ qemu-system-x86_64 -monitor stdio ...

Then you can interact from your shell and scroll back up as usual.
